Standard Test Method for Tensile Strength and Elongation of Pressure-Sensitive Tapes

1.1 This test method covers the measurement of tensile strength (breaking strength) and stretch properties (elongation and "F" value) for pressure-sensitive tapes. It includes procedures for machine- direction and cross-direction tests and tests for tapes with low and high stretch and reinforced backings. It also includes a procedure for obtaining stretch force ("F" value) in conjunction with a determination of tensile strength. These procedures employ a constant-rate-of-extension (CRE)-type testing machine. They apply to the principle of stretching the specimen at a fixed strain rate of one inch per inch of specimen length per minute with the exception of the procedure for reinforced tapes.

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.
