1.1 ,This test method covers the measurement of tensile strength at break (breaking strength) and stretch properties (elongation) for pressure-sensitive tapes and labels. It includes procedures for machine direction and cross direction, for high-strength filament reinforced backings and for high stretch backings. It also includes a procedure for obtaining force (“,F”, value) in conjunction with a specified elongation. These procedures employ a constant-rate-of-extension (CRE)-type testing machine.
