Automotive adhesive standards from SAE International (SAE) focus on the test methods, guidelines, and specifications for adhesive and sealant materials that are used in the manufacture of ground vehicles and related components. These standards were developed by several technical committees, including the Automotive Adhesive and Sealants Committee (.doc download).
This SAE Recommended Practice defines a procedure for determining shear strengths of adhesives used for bonding automotive oil metal substrates.
This SAE Recommended Practice contains a series of test methods for use in measuring the viscosity of automotive-type adhesives, sealers, and deadeners. The test methods which are contained in this document are as follows: 1.1 Brookfield® Method 1.2 Castor-Severs Rheometer or Pressure Flowmeter 1.3 Penetrometer 1.4 Capillary Rheometer 1.5 Plate Rheometers
This SAE Recommended Practice describes a lap shear test method for use in measuring the bonding characteristics of automotive-type adhesives for joining fiber reinforced plastics (FRPs) to themselves and to metals.
This SAE Recommended Practice defines a procedure for the construction and testing of glass to metal lap shears for determining shear strength of sealant adhesives for automotive stationary glass bonding. This procedure can also be used for fiber reinforced plastic (FRP) when used in place of metal.
This SAE Recommended Practice describes a cross peel test method for use in measuring the bonding characteristics of automotive-type adhesives for joining fiber-reinforced plastics to themselves and to metals.
This SAE Recommended Practice defines the information required to repair the various types of plastics found on modern light-duty highway vehicles. Information is included for the repair and refinishing of most plastic body parts, both interior and exterior. Repair information is described for all commonly used plastics including, but not limited to, polyurethanes, polycarbonate blends, modified polypropylenes, polyethylenes and nylons. Repairs can be made to these types of plastics using two-part (2K) repair adhesives, plastic welding, and other materials available from body shop suppliers. When a new type of plastic is being introduced to the market through a new vehicle program, specific repair and refinishing procedures should be provided, following the format in this document. Sheet-molded compounds (SMC), fiber-reinforced plastics (FRP) and carbon fiber reinforced plastics can also be repaired using slightly different procedures and repair materials.
This SAE Recommended Practice shall be used to determine the peel strength achieved by an adhesive when used to bond various decorative, flexible substrates such as cloth supported vinyl or carpet, to rigid (steel), semi-rigid (SMC plastic), or other similar substrates.
This SAE Recommended Practice shall be used to determine the temperature at which an adhesive softens to the point at which it no longer can support a given load.
This recommended practice defines a procedure for the construction of a lap shear specimen for the purpose of testing the bondability of an automotive sealant adhesive to the elastomeric material used in automotive encapsulating. The present practice of encapsulating automotive glass is described as molding elastomeric material onto the outer edge of the glass using thermoplastic or thermosetting material that quickly sets in the mold. The glass is removed from the mold with cured elastomeric material bonded to the perimeter of thee glass. This encapsulated glass module can now be bonded with a sealant adhesive into the body opening of a vehicle.
This SAE Recommended Practice defines a procedure for determining the adhesion strength characteristics of heat-cured metal bonding adhesives subjected to induction heating.
This SAE Recommended Practice defines a procedure for determining the cleavage strength of an adhesive used for bonding automotive oily metal substrates.
This recommended practice defines a procedure for the construction and testing of a 180 deg peel specimen for the purpose of determining the bondability of glass to elastomeric material in automotive modular glass. This test method suggests that elastomeric material of less than 172 mpa modulus be used as the encapsulating material. The present practice of encapsulating automotive glass is described as molded-in-place elastomeric material onto the outer edge of the glass using thermoplastic or thermosetting material that quickly sets in the mold. The glass is removed from the mold with the cured elastomeric material bonded to the perimeter of the glass. This encapsulated glass module can now be bonded with a sealant adhesive into the body opening of a vehicle.
This SAE Recommended Practice applies to evaluation of the conformance match condition existing between two surfaces. Evaluation of this conformance may be especially useful in bonded applications although it may also have relevance to bolted adjacent surface joint conditions. Since good bonding surface conformity is necessary for providing optimal bond performance with pressure sensitive adhesives, the purpose of this document is to provide a method of evaluating the conformance match of the mating surfaces. This document is intended as a guide toward standard practice but may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering the use of this document. Tool types, materials, application tools, and component contact area evaluation methods are included as part of this document. In most cases a visual evaluation of contact performance may be satisfactory; however, for greater accuracy a measurement tool may be used. When reporting a contact value the mode of evaluation (e.g., visual, measurement tool) should be indicated.
The scope of this SAE Recommended Practice is to provide a mechanism for the proper surface preparation and selection of adhesive for the attachment of exterior aftermarket accessories.
This SAE Recommended Practice contains a series of test methods for use in measuring characteristics of automotive-type sealers, adhesives, and deadeners. The test methods which are contained in this document are as follows: ADS-1—Methods of Determining Viscosity ADS-2—Low Temperature Tests ADS-3—Weld-Through Tests ADS-4—Enamel, Lacquer, and Fabric Staining Test ADS-5—Wash-Off Resistance Test ADS-7—Solids Test ADS-8—Flash Point Test ADS-9—Sag and Bridging Tests ADS-10—Flow Test The intent of this document is to provide a series of test methods which can be used in testing the various qualities of sealers, adhesives, and deadener material. In later revisions of this document, attempts will be made to reduce the number of tests now presented. The specific temperatures and times at which some of these tests are to be conducted are not dictated in these test procedures, but they will be found in the material standards which govern each type of material to be tested.
This recommended practice covers the attachment of bonded anti-noise brake pad shims only. Mechanically attached shims (those without bonding) are not covered by this procedure. To measure the strength of the adhesive bond for the attachment of anti-noise shims to disc brake pads or a test specimen to a standard steel plate. Its primary use is as a quality tool.
The choice of the type and grade of solder for any specific purpose depend on the materials to be joined and the method of applying. Those with higher amounts of tin usually wet and bond more readily and have a narrower semi-molten range than lower amounts of tin. For strictly economic reasons, it is recommended that the grade of solder metal be selected that contains least amount of tin required to give suitable flowing and adhesive qualities for application.
This report is an abbreviated summary of metallurgical joining by welding, brazing, and soldering. It is generally intended to reflect current usage in the automotive industry; however, it does include some of the more recently developed processes. More comprehensive coverage of materials, processing details, and equipment required may be found in the Welding Handbook, Soldering Manual, and other publications of the American Welding Society for Testing and Materials. AWS Automotive Welding Committee publications on Recommended Practices are particularly recommended for the design or product engineer. This report is not intended to cover mechanical joining such as rivets or screw fasteners, or chemical joining processes such as adhesive joining.
