ASTM D905-08(2013)

4.1 It cannot be assumed that this test method measures the true shear strength of the adhesive bond. Many factors interfere or bias the measurement including the strength of the wood, the specimen, the shear tool designs themselves, and the rate of loading.

4.2 This test method is suitable for product research and development, qualifying adhesives in accordance with certain product or performance specifications, and monitoring bonding process control. This test method may be suitable for comparing and selecting adhesives, however, such comparisons must be made with caution since the measured strength of some adhesives may be different in different types of joints. Strength values obtained by this test method are not suitable as design shear strengths values without adjustment by certain engineering design factors.

1.1 This test method covers the determination of the comparative shear strengths of adhesive bonds used for bonding wood and other similar materials, when tested on a standard specimen under specified conditions of preparation, conditioning, and loading in compression. This test method is intended primarily as an evaluation of adhesives for wood.

1.2 The values stated in SI units are to be regarded as the standard. The values given in brackets are provided for information purposes only.

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.
