Wood Fastener Standards

Standards for wood fasteners address considerations applicable specifically to fasteners used with wood, as opposed to the more commonly used metal. Wood materials covered are solid timber, glued laminated timber, wood-based sheet products, and bamboo.

ISO 9087:1998

Wood - Determination of nail and screw holding power under axial load application

This International Standard specifies a method for determining the specific resistance of wood to the extraction of nails and screws.

ISO 16670:2003

Timber structures - Joints made with mechanical fasteners - Quasi-static reversed-cyclic test method

ISO 16670:2003 is intended to provide a cyclic test method as a basis for the derivation of parameters which are required in seismic design of timber structures. The method includes procedures to develop the envelope curves (backbone or skeleton curves, an example is given in Clause A.5.) for joints subjected to a cyclic displacement schedule which produces representative demands imposed on the joints by earthquakes. It does not include criteria for parameters which are, at times, stipulated in national standards or building codes. ISO 16670:2003 is intended for joints subjected to lateral load and is not applicable to joints subjected to withdrawal forces. ISO 16670:2003 is applicable to joints made with mechanical fasteners used in timber structures loaded under seismic action.

ISO 6891:1983

Timber structures -- Joints made with mechanical fasteners -- General principles for the determination of strength and deformation characteristics

Applies to joints made with mechanical fasteners used in statically loaded timber structures. Covers the conditioning of test specimens and explains the apparatus to be used for measuring the geometry of the test specimens, their moisture content and other characteristics. Details the loading procedure and specifies the details to be included in the test report.

ISO 27528:2009

Wood-based panels - Determination of resistance to axial withdrawal of screws

ISO 27528:2009 specifies a method for determining the resistance of wood-based panels, of thickness 15 mm and greater, to the withdrawal of screws under axial load. NOTE ISO 27528:2009 establishes fastener holding performance of screws commonly used in applications involving wood-based panels used for building, furniture, cabinet making, joinery or other work in particular regions. Different screws will give different results.

ISO 8969:2011

Timber structures - Testing of punched metal plate fasteners and joints

ISO 8969:2011 specifies test methods for determining the strength and stiffness of joints made with punched metal plate fasteners in load-bearing timber structures, as follows: load-slip characteristics and maximum load resulting from the lateral resistance of the embedded projections, at various angles between the direction of the applied force and the axis of the plate (load-plate angle, ), the direction of the grain of the timber (load-grain angle, ); the tensile strength of the plate at various angles, ; the compression strength of the plate at various angles, (optional test); the shear strength of the plate at various angles, . ISO 8969:2011 is linked to ISO 6891, which gives general test requirements. In addition, a method for testing the nail root in alternate bending is specified in Annex A.

ISO 8970:2020

Timber structures - Testing of joints made with mechanical fasteners - Requirements for timber density

This document specifies a method based on density, for the selection of pieces of wood used in determining the strength and stiffness properties of joints between members of structural timber made with mechanical fasteners. It is intended to be used in conjunction with a test standard specifying a test method. It is assumed that the wood pieces are conditioned to the relevant conditions, that the wood density is normally distributed and that any deviations are reported. This document is applicable only to specimens of structural timber. NOTE It is emphasized that the wood density is only one of the properties that can influence the strength of a joint. Other relevant properties are, for example, growth-ring size and orientation, toughness and hardness.

ISO 10984-2:2009

Timber structures - Dowel-type fasteners - Part 2: Determination of embedding strength

ISO 10984-2:2009 specifies laboratory methods for determining the embedding strength of solid timber, glued laminated timber and wood-based sheet products with dowel-type fasteners. Descriptors: timber construction, fasteners, nails (fasteners), bolts, tests, compression tests, determination, compressive strength

ISO 15629:2002

Pallets for materials handling - Quality of fasteners for assembly of new and repair of used, flat, wooden pallets

ISO15629 gives guidelines on nails and staples used in the assembly of new and repair of used wooden flat pallets. For the purposes of this International Standard the term fasteners applies to nails and staples only. ISO 15629 is prescriptive and performance-based and contains physical descriptions of fasteners as well as minimum recommended performance levels.

ISO 18334:2010

Pallets for materials handling - Quality of assembly of new wooden pallets

ISO 18334:2010 gives guidance on the minimum quality criteria concerning the assembly of new wooden pallets. This includes component placement accuracy, fastening schedules and fastener placement, the clinching of fasteners, and guidelines for the placement of components the characteristics of which impact pallet performance. ISO 18334:2010 does not address safety problems, if any, associated with pallet assembly.

ISO 22156:2021

Bamboo structures - Bamboo culms - Structural design

This document applies to the design of bamboo structures whose primary load bearing structure is made of round bamboo or shear panel systems in which the framing members are made from round bamboo. Except as indicated in Clause 12, this document applies to one- and two-storey residential, small commercial or institutional and light industrial buildings not exceeding 7 m in height. This document is concerned only with requirements for mechanical resistance, serviceability and durability of bamboo structures. This document permits an allowable load-bearing capacity design (ACD) and/or allowable stress design (ASD) approach for the design of bamboo structures. Allowable load-bearing capacity and allowable stress approaches may be used in combination in the same structure. This document additionally recognises design approaches based on partial safety factor design (PSFD) and/or load and resistance factor design (LRFD) methods (5.11.1), previous established experience (5.11.2), or documented "design by testing" approaches (5.11.3). Other requirements, such as those concerning thermal or sound insulation, are not considered. Bamboo structures may require consideration of additional requirements beyond the scope of this document. Execution is covered to the extent that it impacts the quality of construction materials and products required to comply with the design requirements contained herein. This document provides a number of modification factors, designated C i . These are empirically derived factors, based on best available engineering judgement, that are believed to be universally applicable to bamboo materials that are appropriate for building construction. Parameters affecting bamboo material performance are many and are addressed explicitly through the use of experimentally determined characteristic values of strength and stiffness. Annex A provides a summary of the bases upon which the provisions of this document were developed. This document does not apply to - structures made of engineered bamboo products such as glue-laminated bamboo, cross-laminated bamboo, oriented strand, or densified bamboo materials, - bamboo-reinforced materials where bamboo is not the primary load-bearing constituent. This includes bamboo-reinforced concrete, masonry and soil, or, - scaffold structures constructed with bamboo.
