Standard Terminology Relating to Wood-Base Fiber and Particle Panel Materials

1.1 This terminology standard covers a repository of terms and classifications essential for the business of Subcommittee D07.03. 1.2 Terms and classifications for inclusion in this terminology standard when needed for general use in the conduct of the standards over which Subcommittee D07.03 has jurisdiction. 1.3 The terms in this standard pertain to cellulosic boards or panel products derived from wood and the woody tissue of such plants as bagasse, flax, and straw. They fall into two general groups: ( 1 ) those manufactured from lignocellulosic fibers and fiber bundles where in manufacture the interfelting of the fibers and a natural bond are characteristics, and ( 2 ) those boards manufactured from a wide range in size and shape of particles ranging from fine elements approaching fibers in size to large flakes which are blended with synthetic resin adhesive and consolidated into boards characterized by the resin bond and usually known as resin-bonded particleboards or more commonly as particleboards.

ASTM D2718-18

Standard Test Methods for Structural Panels in Planar Shear (Rolling Shear)

1.1 These test methods determine the shear properties of structural panels associated with shear distortion of the planes parallel to the edge planes of the panels. Both shear strength and modulus of rigidity may be determined. Primarily, the tests measure the planar shear (rolling shear) strength developed in the plane of the panel. 1.2 Structural panels in use include, but are not limited to, structural plywood, oriented strand board (OSB), and composites of veneer and of wood-based layers. 1.3 Two test methods are included: 1.3.1 Test Method A Planar shear loaded by plates. 1.3.2 Test Method B Planar shear induced by five-point bending. 1.3.3 The choice of method will be dictated by the purpose of the test and equipment available. 1.3.4 Test Method A, Planar Shear Loaded by Plates This test method uses a rectangular panel section adhered between steel plates with protruding knife edges to create load at the panel faces. This test method has been used to develop shear properties of plywood and oriented strand board for the purpose of confirming design values. This test method does not produce pure shear, but the specimen length is prescribed so that the secondary stresses have a minimum effect. The method determines shear strength and modulus of rigidity. 1.3.5 Test Method B, Planar Shear Induced by Five-Point Bending Planar shear stress is induced on the panel while loaded in bending using two continuous spans. This test method determines planar shear strength consistent with panel applications under transverse loading. This test method is able to determine shear strength at any moisture condition. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D2719-19

Standard Test Methods for Wood Structural Panels in Shear Through-the-Thickness

1.1 These test methods determine the shear through-the-thickness properties of wood structural panels associated with shear distortion of the major axis. Wood structural panels in use include plywood, oriented strand board, and composites of veneer and of wood-based layers. Three test methods are included which differ somewhat in their application: The choice of test method will be determined in part by the purpose of the tests, characteristics of test material, and equipment availability. In general, Test Method B or C for large specimens is preferred when equipment, amount of test material, and experimental plan permit. 1.1.1 Test Method A: Small Panel Shear Test This test method is suitable for testing small samples of uniform material including investigations of the effects of grain direction or orientation and of many raw materials and manufacturing process variables which influence shear properties uniformly throughout the specimen. The test method is unsuited for determining effects of grade and manufacturing features such as density variations, knots, and core gaps within the specimen. 1.1.2 Test Method B: Large Panel Shear Test This test method is regarded as giving the most accurate modulus of rigidity and is therefore recommended for elastic tests of materials to be used in stress analysis studies of test structures. This test method also yields excellent shear strength values for clear material. However, in spite of the large size of the specimen, failures generally occur only in narrow zones at the perimeter of the test area. This characteristic, a result of the heavy perimeter framing, causes this test method to be generally unsuited for determining grade and manufacturing effects such as density variations, core gaps, and knots that are not uniformly distributed throughout the panel. Generally, only in cases where effects of these factors under conditions of heavy perimeter framing are desired, should the test method be applied. 1.1.3 Test Method C: Two-Rail Shear Test This test method is applicable to a wide variety of materials and problems. The specimen fabrication and test procedures are somewhat simpler than in Test Methods A and B. The specimen is free to shear parallel to its 24-in. (610-mm) length dimension anywhere within the 8-in. (203-mm) width between rails. Thus, the test method is well suited for determining grade and manufacturing effects such as core gaps and knots occupying and affecting small areas. The test method is not so ideally suited for determination of modulus of rigidity, but when adjusted for strain distribution effects, values approximating those obtained by Test Method B result. The test method simulates effects of heavy framing when expected planes of weakness are oriented perpendicular to rails and no framing at all when parallel to rails. Note 1: A smaller scale version based on the principles of this two-rail shear method is contained in Test Methods D1037 Section 27. The results from Test Methods D1037 Section 27 may not be equivalent to the results from Test Methods D2719 Method C. 1.2 Significant differences, moderate to small in magnitude, among the three test methods have been found to exist when these test methods are applied to plywood of clear straight-grained veneers. Therefore, when comparisons are made among test results, it is recommended that the same test method be used throughout. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D3043-17

Standard Test Methods for Structural Panels in Flexure

1.1 These test methods determine the flexural properties of strips cut from structural panels or panels up to 4 by 8 ft in size. Structural panels in use include plywood, waferboard, oriented strand board, and composites of veneer and of wood-based layers. Four methods of tests are included: The choice of method will be dictated by the purpose of the test, type of material, and equipment availability. All methods are applicable to material that is relatively uniform in strength and stiffness properties. Only Method C should be used to test material suspected of having strength or stiffness variations within a panel caused by density variations, knots, knot-holes, areas of distorted grain, fungal attack, or wide growth variations. However, Method B may be used to evaluate certain features such as core gaps and veneer joints in plywood panels where effects are readily projected to full panels. Method C generally is preferred where size of test material permits. Moments applied to fail specimens tested by Method A, B or D in which large deflections occur can be considerably larger than nominal. An approximate correction can be made. 1.2 Method A, Center-Point Flexure Test This method is applicable to material that is uniform with respect to elastic and strength properties. Total deflection, and modulus of elasticity computed from it, include a relatively constant component attributable to shear deformation. It is well suited to investigations of many variables that influence properties uniformly throughout the panel in controlled studies and to test small, defect-free control specimens cut from large panels containing defects tested by the large-specimen method. 1.3 Method B, Two-Point Flexure Test This method, like Method A, is suited to the investigation of factors that influence strength and elastic properties uniformly throughout the panel, in controlled studies, and to testing small, defect free control specimens cut from large specimens tested by Method C. However, it may be used to determine the effects of finger joints, veneer joints and gaps, and other features which can be placed entirely between the load points and whose effects can be projected readily to full panel width. Deflection and modulus of elasticity obtained from this method are related to flexural stress only and do not contain a shear component. Significant errors in modulus of rupture can occur when nominal moment is used (see Appendix X1 ). 1.4 Method C, Large Panel Test This method is ideally suited for evaluating effects of knots, knot-holes, areas of sloping grain, and patches for their effect on standard full-size panels. It is equally well suited for testing uniform or clear material whenever specimen size is adequate. Specimen size and span above certain minimums are quite flexible. It is preferred when equipment is available. 1.5 Method D, Flexure Test for Quality Assurance This method, like Method A, is well suited to the investigation of factors that influence bending strength and stiffness properties. Also like Method A, this method uses small specimens in a center-point simple span test configuration. This method uses a span to depth ratio, specimen width, test fixture and test speed that make the method well suited for quality assurance. The method is frequently used for quality assurance testing of oriented strand board. 1.6 All methods can be used to determine modulus of elasticity with sufficient accuracy. Modulus of rupture determined by Methods A, B or D is subject to errors up to and sometimes exceeding 20 % depending upon span, loading, and deflection at failure unless moment is computed in the rigorous manner outlined in Appendix X1 or corrections are made in other ways. These errors are not present in Method C. 1.7 When comparisons are desired between results of specimen groups, it is good practice to use the same method of test for all specimens, thus eliminating possible differences relatable to test method. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D3044-16

Standard Test Method for Shear Modulus of Wood-Based Structural Panels

1.1 This test method covers determination of the shear modulus of wood-based structural panels associated with shear distortion in the plane of the panels. The method is applicable to all types of wood-based structural panels. The grain direction or orientation of the individual plies, laminations, or layers shall be parallel or perpendicular to the edge of the test specimen. If the plies, laminations, or layers are of different material or elastic properties, the method gives the effective shearing modulus. Wood-based structural panels in use include plywood, oriented strand board, and composites of veneer and of wood-based layers. Note 1: This test method is primarily designed for material in which the grain or orientation of the individual plies, laminations, or layers is parallel or perpendicular to the edge of the specimen. It may be used, however, for plywood specimens in which the grain is at 45 to the specimen edges if a four-ply panel with all plies of the same thickness is used. The controlling condition is that the EI (modulus of elasticity moment of inertia) values along both diagonals shall be equal. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D3499-19

Standard Test Method for Toughness of Wood Structural Panels

1.1 This test method for toughness of wood structural panels covers the determination of energy necessary to cause failure by impact loading of a beam specimen which is simply supported and loaded at midspan. Wood structural panels in use include plywood, oriented strand board, and composites of veneer and of wood-based layers. 1.2 The values stated in inch-pound units are to be regarded as standard.

ASTM D3500-20

Standard Test Methods for Wood Structural Panels in Tension

1.1 These test methods cover the determination of the tensile properties of wood structural panels. 1.2 Wood structural panels in use include plywood, oriented strand board and composites of veneer, and other wood-based layers. 1.3 Test Method A, Tensile Test for Small Specimens: 1.3.1 This test method employs small specimens that should have a reduced cross section at the center of their length to avoid failure in the grip area. The transition from full width of specimen to reduced section at the center should be gradual to minimize stress concentration. 1.3.2 When the measurements of elastic properties are to be made, the length of the reduced cross section at the center should be of sufficient length to accommodate an extensometer. 1.4 Test Method B, Tensile Test for Large Specimens: 1.4.1 This test method employs large specimens and responds well to manufacturing variables, panel grade characteristics, and other variables influencing the tensile properties of structural panels. 1.4.2 The test specimens are large enough to contain the maximum sized grade characteristics found in panels. The test specimens have a constant cross section since the size and location of grade characteristics control the location of failures and the effect of stress concentration at the grips is overshadowed. 1.4.3 This test method is recommended for the following: 1.4.3.1 Comparative tests of wood structural panels, 1.4.3.2 Determining the influence of any specific strength reducing variables on the tensile properties of wood structural panels, 1.4.3.3 Determination of tensile properties of panels for use in developing structural recommendations. 1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D3501-05a(2018)

Standard Test Methods for Wood-Based Structural Panels in Compression

1.1 These test methods cover the determination of the compression properties of wood-based structural panels. Wood-based structural panels in use include plywood, waferboard, oriented strand board, and composites of veneer and of wood-based layers. 1.2 Method A, Compression Test for Small Specimens This method is applicable to small specimens that are uniform with respect to elastic and strength properties. Two types of compression tests are employed: one to evaluate both elastic and compressive strength properties, and the second to evaluate maximum compressive strength only. 1.3 Method B, Compression Test for Large Specimens This method employs large specimens and responds well to manufacturing variables and growth characteristics that influence compression properties of structural panels. 1.3.1 This method is intended for the following: 1.3.1.1 Comparative tests of structural panels, 1.3.1.2 Evaluating the effects of moisture content on strength properties of structural panels, 1.3.1.3 Determining the strength properties of structural panels, and 1.3.1.4 Evaluating the effects of raw material and manufacturing variables on compression properties of structural panels. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D5582-14

Standard Test Method for Determining Formaldehyde Levels from Wood Products Using a Desiccator

1.1 This test method covers a small scale procedure for measuring formaldehyde emission potential from wood products under defined test conditions. The formaldehyde level is determined by collecting air-borne formaldehyde in a small distilled water reservoir within a closed desiccator. The quantity of formaldehyde is determined by a modification of the National Institute for Occupational Safety and Health (NIOSH) 3500 chromotropic acid test procedure. Other analytical procedures may be used to determine formaldehyde emission potential provided that such methods give similar results to the chromotropic acid procedure. However, the test results and test report must be properly qualified and the analytical procedure employed must be noted. Procedures based on acetylacetone and pararosaniline have been found to give similar results to chromotropic acid in other test methods used in determining formaldehyde emission potential from wood products (see Test Method E1333 ). 1.2 Wood products typically evaluated by this test method are made with urea-formaldehyde adhesives and include particleboard, hardwood, plywood, and medium-density fiberboard. This test method is used for product quality control and is a small bench test method that correlates with the large-scale acceptance test for determining formaldehyde levels from wood products, Test Method E1333 . The general desiccator testing procedure may be modified for different conditioning times to accommodate its use in manufacturing quality control. However, the test results must be properly qualified and the conditioning time employed must be noted. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 6 and 8.2.5 .

ASTM D5651-13

Standard Test Method for Surface Bond Strength of Wood-Base Fiber and Particle Panel Materials

1.1 This test method is a measure of the cohesive bond strength of the fibers, or particles, on the surface of wood-base fiber and particle panels (for example, particleboard and medium-density fiberboard) in the direction perpendicular to the plane of the panel. 1.1.1 To determine the internal cohesive bond strength of wood-base fiber and particle panels, use Section 11 of Test Methods D1037. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This test method does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D6007-14

Standard Test Method for Determining Formaldehyde Concentrations in Air from Wood Products Using a Small-Scale Chamber

1.1 This test method measures the formaldehyde concentrations in air emitted by wood product test specimens under defined test conditions of temperature and relative humidity. Results obtained from this small-scale chamber test method are intended to be comparable to results obtained from testing larger product samples by the large chamber test method for wood products, ASTM Test Method E1333 . The results may be correlated to values obtained from ASTM Test Method E1333 . The quantity of formaldehyde in an air sample from the small chamber is determined by a modification of NIOSH 3500 chromotropic acid test procedure. As with ASTM Test Method E1333 , other analytical procedures may be used to determine the quantity of formaldehyde in the air sample provided that such methods give results comparable to those obtained by using the chromotropic acid procedure. However, the test results and test report must be properly qualified and the analytical procedure employed must be accurately described. 1.2 The wood-based panel products to be tested by this test method are characteristically used for different applications and are tested at different relative amounts or loading ratios to reflect different applications. This is a test method that specifies testing at various loading ratios for different product types. However, the test results and test report must be properly qualified and must specify the make-up air flow, sample surface area, and chamber volume.

ASTM D6643-01(2016)

Standard Test Method for Testing Wood-Base Panel Corner Impact Resistance

1.1 This test method shall be used to measure the relative corner impact resistance and other damage that may occur during the rough handling of wood-base panels or composite materials. This test method is suitable for all wood-base panels such as plywood, oriented strand board, hardboard, particleboard and medium density fiberboard as well as other composite panel products. 1.2 This test method covers determination and evaluation of the effects of panels being dropped from various heights with a predetermined amount of dead load and angle of impact to simulate an equivalent field application. 1.3 The values of all information will be stated in English units and regarded as standard. The SI values are written in parentheses. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D7033-14

Standard Practice for Establishing Design Capacities for Oriented Strand Board (OSB) Wood-Based Structural-Use Panels

1.1 This practice covers the basis for code recognition of design capacities for OSB structural-use panels. Procedures are provided to establish or re-evaluate design capacities for OSB structural-use panels. Procedures for sampling and testing are also provided. Design values stated as capacity per unit dimension are to be regarded as standard. Design capacities developed in accordance with this practice are applicable to panels intended for use in dry in-service conditions. Note 1 This practice is based on ICC-ES Acceptance Criteria AC-182. Relative to the scope of AC-182, this practice is limited to OSB panels. Note 2 While this practice makes reference to PS-2, this practice applies similarly to products certified to other standards such as CAN/CSA O325. Note 3 OSB produced under PS-2 is rated with the Exposure 1 bond classification. Exposure 1 panels covered by PS-2 are intended for dry use applications where the in-service equilibrium moisture content conditions are expected to be less than 16 %. Exposure 1 panels are intended to resist the effects of moisture due to construction delays, or other conditions of similar severity. Guidelines on use of OSB are available from manufacturers and qualified agencies. Note 4 PS-2-10 replaced the use of nominal thicknesses with a classification term known as Performance Category, which is defined in PS-2 as A panel designation related to the panel thickness range that is linked to the nominal panel thickness designations used in the International Building Code (IBC) and International Residential Code (IRC). Therefore, the PS-2 Performance Category should be considered equivalent to the term nominal thickness used within this standard.

ASTM D7433-19

Standard Test Method for Measuring Surface Water Absorption of Overlaid Wood-Based Panels

1.1 This test method covers the determination of the quantity of water absorbed in a specified time through the surface of an overlaid wood-based panel. The test method measures the rate of water gain within a controlled surface area of the overlaid panel surface when exposed to standing water. The method was adapted from the principles of Test Method D5795 . 1.2 This test method is applicable to various overlaid wood-based panels including, but not limited to, plywood (such as MDO grades and HDO grades referenced in PS 1 09), oriented strand board, medium density fiberboard, particleboard, and hardboard. 1.3 This test method does not address sampling procedures, number of replications nor performance criteria since those details vary depending upon the purpose of the testing and the type of product. The method is specific to the panel surface and does not evaluate water absorption or edge swell that may occur along panel edges. The method does not consider the variables related to in-service moisture conditions and therefore does not claim to directly relate to water absorption that may occur in actual panel use situations. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.5 This test method does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this test method to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D7519-11

Standard Test Method for Internal Bond Strength and Thickness Swell of Cellulosic-Based Fiber and Particle Panels After Repeated Wetting

1.1 These test methods provide a measure of the moisture resistance of cellulosic-based fiber and particle panels (for example, medium-density fiberboard (MDF), particleboard, and hardboard). Resistance to moisture changes is measured by dimensional and internal bond changes and does not refer to decay/mold resistance or other performance aspects. 1.2 These test methods do not address structural properties or performance following moisture exposure. Panels are subjected to repeated cycles of water submersion and oven drying. After three cycles, the test specimens are tested for thickness swelling (TS) and internal bond (IB) strength. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D7770-12(2019)

Standard Test Method for Collection of Volatile Organic Compounds Emitted During Simulated Manufacturing of Engineered Wood Products Via a Sealed Caul Plate Method

1.1 This test method provides a method for the collection of volatile organic compounds (VOC) that are emitted during the manufacture of engineered wood products using a laboratory environment designed to simulate a defined production process. The method is used for the determination of the amounts of methanol, formaldehyde, phenol and other VOC that may be emitted during conditions designed to simulate production such as hot pressing, the conditions of hot stacking and cool-down that occurs post-press. 1.2 The test method was originally developed to measure certain VOC from exterior plywood meeting Voluntary Product Standard PS 1 09 and structural composite lumber products such as laminated veneer lumber (LVL) meeting Specification D5456 . Both of these product types are typically manufactured using phenol-formaldehyde resin based adhesives that meet Specification D2559 . 1.3 The test method is suitable for many types of wood products bonded with adhesives. 1.4 This test method is specific for collecting VOC during simulated production of wood products and is not designed to determine general organic emissions from all indoor materials or sources. 1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Section 7 on Hazards. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E1333-14

Standard Test Method for Determining Formaldehyde Concentrations in Air and Emission Rates from Wood Products Using a Large Chamber

1.1 This test method measures the formaldehyde concentration in air and emission rate from wood products containing formaldehyde under conditions designed to simulate product use (see 11.5 and Note 9 ). The concentration in air and emission rate is determined in a large chamber under specific test conditions of temperature and relative humidity. The general procedures are also intended for testing product combinations at product-loading ratios and at air-exchange rates typical of the indoor environment ( 1 ) . 2 The products tested, the loading ratios and the air exchange rates employed are described in the test report. 1.2 This test method determines the average formaldehyde concentration in air and emission rate from a number of large size samples. The average concentration and emission rate reported, thus, will not provide information on higher or lower emitting panels in the test lot. 1.3 This method is primarily used for testing newly manufactured panel products that are shipped for testing either seal-wrapped in polyethylene or with waster sheets, or with both. When this test method is used for evaluating other than newly manufactured panel products (after original application, installation or use), the method of packaging and shipping the product for testing shall be described in the test report.
