1.1This test method covers procedures for evaluating passenger car tires for sidewall component integrity and cracking resistance, using an outdoor roadwheel.

1.2This test method evaluates the resistance of tire sidewalls to dynamic weathering, atmospheric ozone cracking, fatigue cracking, or openings of splices within, or of junctures between, sidewall components and cracking at molded sidewall elements.

1.3This test method is useful for evaluating tire black sidewalls, white, or other colored, sidewalls, and coverstrips.

1.4This test method is limited to comparative performance testing between a "control" sidewall component or assembly and one or more experimental alternatives that are built onto the same tire ("multisection") or onto tires that are identical in all respects other than the sidewall variation.

1.5This test method is not applicable to evaluation of sidewall resistance to abrasion, as may be experienced in severe cornering or curb scuffing.

1.6The values stated in SI units are to be regarded as the standard.

1.7This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precaution statements, see 5.2.

1.8This 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.
