ASTM D4501-01(2009)e1
(Test Method)Standard Test Method for Shear Strength of Adhesive Bonds Between Rigid Substrates by the Block-Shear Method
Standard Test Method for Shear Strength of Adhesive Bonds Between Rigid Substrates by the Block-Shear Method
SIGNIFICANCE AND USE
This test method provides an estimate of the shear strength of an adhesive on various machinable and nonmachinable substrate materials. It is particularly applicable for testing bonds between ceramic, glass, magnet moldings, and plastic parts with one flat face where machining would be difficult or impractical.
SCOPE
1.1 This test method describes a procedure and fixture used to determine shear strengths of adhesives used to bond materials with moduli higher than the modulus of the adhesive. The size and shape of the specimens are variable within the physical restraints of the fixture.
1.2 The values stated in SI units are to be regarded as the 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.
