ASTM D2095-96e1

Standard Test Method for Tensile Strength of Adhesives by Means of Bar and Rod Specimens

SCOPE
1.1 This test method covers the determination of the relative tensile strength of adhesives by the use of bar- and rod-shaped butt-joined specimens under defined conditions of preparation, conditioning, and testing. This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations.  
Note 1-An alternative test method for determining the tensile strength of adhesives is Test Method D 897.  
1.2 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.
