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.

Failure is indicated by a complete rupture of the test specimen. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. A large number of specimens may, therefore, be required to yield the desired precision.

We offer d442, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. By means of our testing expertise and modular product design, we will help find the solution that is right for you. The strain cycle is characteristic of the type of test apparatus specified.

During part asrm the cycle, the strain is relaxed to a zero value. The values d44482 in parentheses are for information only. Natural rubber, for example, has shown a narrower distribution than many synthetic rubbers. This standard does not purport to address all of the safety concerns, if any, associated with its use.

This is due to the varied nature of service conditions. The specimens are tested without intentionally initiated flaws, cuts, or cracks. During part of the cycle, the strain is relaxed to a zero value. Comparison of different rubber compounds should be made with due consideration to the standard deviation for each see 7.

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.

Failure is indicated by a complete rupture of the test specimen. 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.

ASTM D4482 Rubber Property-Extension Cycling Fatigue

Active view current version of standard. Failure is indicated by a complete rupture of the test specimen. The specimens are aztm without intentionally initiated flaws, cuts, or cracks. 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 values given in parentheses are for information only. 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. These test procedures do yield data that can be used for the comparative evaluation of rubber compounds for d44822 ability to resist dynamic extension cycling fatigue.

The information obtained ashm be useful in predicting the flex-life performance of a compound in active service; however, the user should be x4482 that in actual use, products are subjected to many other fatigue factors not measured in this test method. This is due to the varied nature ashm service conditions. The specimens are tested without intentionally initiated flaws, cuts, or cracks. We are confident that we have what you are looking for.

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.
