ASTM D5849/D5849M-21

Standard Test Method for Evaluating Resistance of Modified Bituminous Roofing Membrane to Cyclic Fatigue (Joint Displacement)

SIGNIFICANCE AND USE
5.1 This test method provides data on classifying polymer-modified bituminous membranes by their performance related to the fatigue conditions to which they are subjected.  
5.2 This test method is applicable to testing specimens consisting of a single ply of the polymer-modified bitumen material or a multiple-ply composite that includes the polymer-modified bitumen material.  
5.3 This test method is conducted on both unaged and heat-aged specimens to determine the effect of heat exposure on the membrane material's ability to resist deterioration from cyclic strain. This test method may also be conducted on specimens subjected to other laboratory exposure conditions that are not specified herein.
SCOPE
1.1 This test method determines the effect of constant cyclic displacement on polymer-modified bituminous membrane specimens. In this test method, a relatively low travel rate of cycling is used and the material is tested for a specified number of cycles under conditions of increased amplitude or lower 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 nonconformance with the standard.  
1.3 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, 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.

during 500 cycles (Note 1) at predetermined temperature and cycle amplitude conditions. If the specimen passes the test under the
selected conditions, the severity of the test is raised by either lowering the temperature or increasing the amplitude of the cycle,
or both (see Table 1). Similarly, heat-aged specimens are subjected to 200 cycles (Note 1) under the same conditions of temperature
and cycle amplitude. Test the membrane until failure or until Test Condition No. 5 is achieved.
NOTE 1—Other numbers of cycles may be used depending on the reason for conducting the test, for example, to determine the number of cycles necessary
to produce failure.
