ASTM D4482 PDF

Historical Version s - view previous versions of standard. More D The strain cycle is characteristic of the type of test apparatus specified. Experience in fatigue testing shows that fatigue life may have a wide, non-normal distribution and, therefore, a large standard deviation that is compound dependent.

ASTM D D determines the fatigue life of rubber compounds undergoing a tensile-strain cycle. During part of the cycle, the strain is relaxed to a zero value. The specimens are tested without intentionally initiated flaws, cuts, or cracks. Failure is indicated by a complete rupture of the test specimen.

ASTM D4482 Rubber Property-Extension Cycling Fatigue

During part of the cycle, the strain is relaxed to a zero value. The specimens are tested without intentionally initiated flaws, cuts, or cracks. Failure is indicated by a complete rupture of the test specimen. This is due to the varied nature of service conditions. These test procedures do yield data that can be used for the comparative evaluation of rubber compounds for their ability to resist dynamic extension cycling fatigue. The values given in parentheses are for information only. 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.

This test determines the fatigue life of rubber compounds when they undergo a continual tensile-strain cycle. The specimens are tested as whole, with no cuts, cracks or flaws. Failure is indicated by a complete rupture of the test specimen, so any imperfections may be an unwanted catalyst. This standard details one procedure for determining fatigue life, which gives an estimate of the crack initiation behavior of rubber vulcanizate. While the information may be useful in predicting the flex-life performance of a compound in actual service flex fatigue , there will be many other fatigue factors in a real-life environment that are not measured in this test method.
