ASTM D7105-06(2013)

5.1 This test method is useful to define the force needed to cause separation of the roofing or waterproofing system or components perpendicular to the plane of the system, and to define the weakest plane in the system.

1.1 This test method measures the force needed to cause separation of the components of a roofing or a waterproofing membrane system normal (perpendicular) to the plane of the membrane. The separation may be adhesive at the weakest bond, or cohesive within the weakest material. If the failure is cohesive, the adhesive strength is greater than the cohesive strength.

1.2 The values stated in SI units are regarded as standard. The values given in parentheses are for information only.

1.3 The 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.
