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 D4482 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. During part of the cycle, the strain is relaxed to a zero value.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The d448 are asrm without intentionally initiated flaws, cuts, or cracks. Failure is indicated by a complete rupture of the test specimen. 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.

ASTM D D determines the fatigue life of rubber compounds undergoing a tensile-strain cycle.

ASTM D Rubber Property-Extension Cycling Fatigue

This is due to the varied nature of service conditions. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, ast, and humidity chambers, furnaces, baths and custom solutions for unique applications. Link to Active This link will always route to the current Active version of the standard. The strain cycle is characteristic of the type of test apparatus specified.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Force range of 5 kN to kN 1, x4482 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 specimens are tested without intentionally initiated flaws, cuts, or cracks.

The values given in parentheses are for information only. This is due to the varied nature of service conditions. Failure is indicated by a complete rupture of the test specimen.

Comparison of different rubber compounds should be made with due consideration to the standard deviation for each see 7. Experience in fatigue satm shows that fatigue life may have a wide, non-normal distribution and, therefore, a large standard deviation that is compound dependent. This standard does not purport to address all of the safety concerns, if any, associated with its use.

Failure is indicated by a complete rupture of the test specimen. 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. Historical Version s – view previous versions of standard.

ASTM D4482

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

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