    Significance and Use

    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. Scope

    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 either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

    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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
