Standard Test Method for Flexural Strength of Adhesive Bonded Laminated Assemblies
5.1 This test method is designed for both wood and metal bonded specimens.
5.2 The test method provides a means to compare flexural properties between assemblies.
5.3 The data are reduced to a comparable basis by means of the formulas given in 11.1 and 11.2. It is recognized that these formulas do not apply rigidly to tests made in the manner described in this method, but serve only to reduce the data to a comparable basis.
1.1 This test method covers the determination of the comparative properties of either metal or wood adhesive bonded assemblies when subjected to flexural stresses with standard shape specimens and under defined conditions of pretreatment, temperature, relative humidity, and testing technique. The test specimen and testing technique were designed to develop a large portion of shear forces between the laminae of the test piece when the load is applied, rather than to reduce shear stress to a minimum as is done in other ASTM test methods for flexural properties. This method is not applicable to assemblies made with nonrigid adherends. The data obtained are not suitable for design work.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information purposes.
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.
