Standard Test Method for Breaking Strength and Elongation of Pressure-Sensitive Tape

Abstract

5.1 This test method provides information that can be used in material specifications for product design and quality assurance applications. It can be used in comparing different products. 5.2 The use of this test method must be related to the purpose for which the test is performed. One purpose is for determining the relative strength of the tape in the size in which it is purchased or used. Another purpose is to identify or characterize a particular backing material. 5.2.1 The test may be performed on the tape as-received, that is, without cutting the material to a specimen width less than the as-received width. Usually tapes wider than 48 mm [2 in.] are not tested due principally to the limitations of equipment. Tapes as narrow as approximately 3 mm [0.125 in.] can be tested. 5.2.2 The test may be performed on a specimen cut from within the sample material boundaries using a sharp razor cutter, such as that defined in Section 6. This method is usually used for material characterization, determining quality of conformance, and for specification compliance. 5.3 Stretch characteristics of elongation at break or force to a specified elongation can be related to the tape's intended use or for identifying or characterizing a material.
