ASTM D(). Standard Test Method for Rubber Property-Extension Cycling Fatigue. standard by ASTM International, 10/01/ View all product. ASTM D describes a procedure in which a test specimen is cyclically strained, at a fixed frequency, over a series of maximum extensions (flexing). ASTM D is also referred to as the “fatigue—to—failure” test, as a function of the popular instrument used to perform the test. ASTM D describes a.

ASTM D – 07 Standard Test Method for Rubber Property-Extension Cycling Fatigue

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. Failure is indicated by a complete rupture of the test specimen. During part of the cycle, the strain is relaxed to a zero value.

Failure is indicated by a complete rupture of the test specimen. The strain cycle is characteristic of the type of test apparatus specified.

Testing Standards List

Experience in fatigue testing shows that fatigue life may have a wide, non-normal distribution and, therefore, a large xstm deviation that is compound dependent. 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.

Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests F4482 dual column testers are available in both tabletop and floor standing models. ASTM D D determines the fatigue life of rubber compounds undergoing a tensile-strain cycle. A large number of specimens may, therefore, be required to yield the desired precision.

We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and x4482 chambers, furnaces, baths and custom solutions for unique applications. Have a question about conducting the test for this standard?

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. This xstm due to the varied nature of service conditions. The specimens are tested without intentionally initiated flaws, cuts, or cracks. Failure is indicated by a complete rupture of the test specimen. The information obtained may be useful in predicting the flex-life performance of a compound in active service; however, the user should be aware that in actual use, products are subjected to many other fatigue factors not measured in this test method.

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.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Natural rubber, for example, has shown a narrower distribution than many synthetic rubbers.
