ASTM D4482 PDF

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.

During part of the cycle, the strain is relaxed to a zero value. 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.

A large d448 of specimens may, therefore, be required to yield the desired precision. Failure is indicated by a complete rupture of the test specimen. D44482 specimens are tested without intentionally initiated flaws, cuts, or cracks. Have a question about conducting the test for this standard?

ASTM D D determines the fatigue life of rubber compounds undergoing a tensile-strain cycle. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

Natural rubber, for example, has shown a narrower distribution than many synthetic rubbers.

The values given in parentheses are for information only. Active view current version of standard. 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.

The specimens are tested without intentionally initiated flaws, cuts, or cracks.

This standard does not purport to address all of the safety concerns, if any, associated with its use. The specimens are tested without intentionally initiated flaws, cuts, or cracks.

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. By means of our testing expertise and modular product design, we will help find the solution that is right for you.

This is due to the varied nature of service conditions. Comparison of different rubber compounds should be made with due consideration to the standard deviation for each see 7.
