ASTM D5683/D5683M-95(2017)
(Test Method)Standard Test Method for Flexibility of Roofing and Waterproofing Materials and Membranes
Standard Test Method for Flexibility of Roofing and Waterproofing Materials and Membranes
SIGNIFICANCE AND USE
5.1 This test method is designed to aid those interested in the engineering properties of roofing and waterproofing sheet materials and membranes.
5.2 This test method enables a researcher to measure the relative flexibility of roofing and waterproofing sheet materials and membranes under standard conditions in the laboratory.
5.3 The data obtained from this test method will not permit prediction of the service life of a membrane. Membrane flexibility is important during application, and changes in flexibility are believed to be linked to the performance of roofing and waterproofing membranes, but the actual link between test data and performance is unknown and is dependent on the materials and exposure.
SCOPE
1.1 This test method measures the flexibility of roofing or waterproofing sheet materials or membranes by bending the test material over a block containing arcs of specific radii at a standard temperature.
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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
