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.

The values given in parentheses are for information only. Comparison of different rubber compounds should be made with due consideration to the standard deviation for each see 7. A large number of specimens may, therefore, be required to yield the desired precision. Link to Active This link will always route to the current Active version of the standard. The specimens are tested without intentionally initiated flaws, cuts, asrm cracks. This is due to the varied nature of service conditions.

Historical Version s – view previous versions of standard. During part of the cycle, the strain is relaxed to a zero value.

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.

Natural rubber, for example, has shown a narrower distribution than many synthetic rubbers. ASTM D D determines the fatigue life of rubber compounds undergoing a tensile-strain cycle.

Testing Standards List

We are confident that we have what you are looking for. Failure is astn by a complete rupture of the test specimen. 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 and d44482 practices and determine the applicability of regulatory limitations prior to use.

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

The information obtained may be useful in predicting aatm 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. By means of our testing expertise and modular product design, we will help find the solution that is right for you. The specimens are tested without intentionally initiated flaws, cuts, or cracks.

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.

The values given in parentheses are for information only. Failure is indicated by a complete rupture of the test specimen.

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. This is due to the varied nature of service conditions.
