CONTAINED IN VOL. 08.03, 2017 Describes the determination of dynamic full reversed fatigue properties of plastics in flexure.

1.1This test method covers the determination of dynamic full reversed fatigue properties of plastics in flexure. This method is applicable to rigid and semi-rigid plastics. Stress and strain levels are below the proportional limit of the material where the strains and stresses are relatively elastic. Three-point or four-point bending systems are used to determine these properties.

1.2This test method can be used with two procedures:

1.2.1Procedure A, designed for materials that use three-point loading systems to determine flexural strength. Three-point loading system is used for this procedure.

1.2.2Procedure B, designed for materials that use four-point loading systems to determine flexural strength. Four-point loading system is used for this procedure.

1.3Comparative tests can be run in accordance with either procedure, provided that the procedure is found satisfactory for the material being tested.

1.4The values stated in SI units are to be regarded as the standard. The values provided in parentheses are for information only.

1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

Note 1:This standard and ISO 13003 address the same subject matter, but differ in technical content and results cannot be directly compared between the two test methods.

1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
