Significance and Use

This standard practice establishes a method for conducting accelerated laboratory aging of radial passenger or light truck tires, or both, in an oven.

The goal of this practice is to define a scientifically valid protocol for the accelerated laboratory aging of a tire such that certain of its material properties correlate to those of in-service tires (see Appendix X1). This practice does not establish performance limits or tolerances for tire specifications.

1. Scope

1.1 This practice describes a method to laboratory age a new tire in an oven to produce changes in certain chemical and physical properties at the belt edges similar to those of tires in-service (see Appendix X1).

1.2 This practice is a precursor to conducting an ASTM standard roadwheel test method for laboratory generation of belt separation in radial passenger car and light truck tires.

1.3 This practice may not produce representative chemical and physical property changes in any part of the tire except the belt edge.

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

1.5 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 and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 8.
