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.

Comparison of different rubber compounds should be made with due consideration to the standard deviation for each see 7. This standard does not purport to address all of the safety concerns, if any, associated with its use.

Give our test engineers a call today for help configuring the best test machine and accessories according to your standard. This is due to the varied nature of service conditions.

A large number of specimens may, therefore, be required to yield the desired precision. Historical Version s – view previous versions of standard. Natural rubber, for example, has shown a narrower distribution than many synthetic rubbers. The values given in parentheses are for information only. During part of the cycle, the strain is d442 to a zero value.

ASTM D4482 Rubber Property-Extension Cycling Fatigue

The specimens are tested without intentionally initiated flaws, cuts, or cracks. Failure is indicated by a complete rupture of the test specimen.

Have a question about conducting the test for this 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.

ASTM D D determines the fatigue life of rubber compounds undergoing a tensile-strain cycle. This is due to the varied nature of service conditions. Link to Active This link will always route to the current Active version of the standard.

Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. The values given in parentheses are for information only. Failure is indicated by a complete rupture of the test specimen. During part of the cycle, the strain is relaxed to a zero value.

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.

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. We are confident that we have what you are looking for.

aztm The specimens are tested without intentionally initiated flaws, cuts, or cracks. The strain cycle is characteristic of the type of test apparatus specified. 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.

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

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. Active view current version of standard. During part of the cycle, the strain is relaxed to a zero value. 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.

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.
