1.1 These test methods cover procedures for testing the static adhesional strength of rubber to rigid materials (in most cases metals). Method A- Rubber Part Assembled Between Two Parallel Metal Plates. Method B- 90° Stripping Test-Rubber Part Assembled to One Metal Plate. Method C- Measuring Adhesion of Rubber to Metal with a Conical Specimen. Method D- Adhesion Test-Post-Vulcanization (PV) Bonding of Rubber to Metal. Method E- 90° Stripping Test-Rubber Tank Lining-Assembled to One Metal Plate. 1.2 While the test method may be used with a wide variety of rigid materials, such materials are the exception rather than the rule. For this reason, we have used the word "metal" in the text rather than "rigid materials." 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 This standard does not purport to address all of the safety problems, 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.
