ASTM D2095-96(2015)

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

SIGNIFICANCE AND USE
4.1 Tension tests provide reasonably accurate information with regard to the tensile strength of adhesives. Tensile strength data may be suitable for specification acceptance, service evaluation, manufacturing control, research, and development. Tension tests are not considered significant for applications differing from the test in rate, direction, and type of loading.
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 D897.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information 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.
