scope:

1.1 This test method covers the determination of fatigue of tire cords in rubber due to compression or extension, or both, using a disk fatigue tester. The fatigue is measured as a loss in strength.

1.2 The values stated in either SI units or other units (in parentheses) are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other.

This 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 to determine the applicability of regulatory limitations prior to use.
