1.1 本规范涵盖P225/60R16 97S子午线标准参考试验轮胎的一般要求。本规范所涵盖的轮胎主要用作制动牵引力、雪地牵引力和磨损性能评估的参考轮胎，但也可用于其他评估，如路面粗糙度、噪音或其他需要参考轮胎的测试。 1.1.1 其他标准参考试验轮胎也用于这些目的，并在第节中引用 2. 。 1.2 本规范提供了轮辋直径为16的标准轮胎设计和构造、标准尺寸，并规定了储存条件。 1.3 截至2020年 E1136 P195/75R14 92S标准参考试验轮胎已停产。这个 F2493 P225/60R16 97S标准参考试验轮胎可用于 E1136 作为试验方法的参考轮胎 F1805 和 E1337 。 1.4 以英寸-磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers the general requirements for the P225/60R16 97S radial standard reference test tire. The tire covered by this specification is primarily for use as a reference tire for braking traction, snow traction, and wear performance evaluations, but may also be used for other evaluations, such as pavement roughness, noise, or other tests that require a reference tire. 1.1.1 Other standard reference test tires are also used for these purposes and are referenced in Section 2 . 1.2 This specification provides a 16 rim diameter code standard tire design and construction, standard dimensions, and specifies the conditions of storage. 1.3 As of 2020 the E1136 P195/75R14 92S Standard Reference Test Tire has ceased production. The F2493 P225/60R16 97S Standard Reference Test Tire is an acceptable replacement for E1136 as the reference tire for Test Methods F1805 and E1337 . 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This 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.
