Description

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

1.2 This 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.

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

1.4 This 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.

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

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

1.7 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 precaution statements, see 5.2
