1.1 本试验方法包括测量已安装充气轮胎车轮总成的车轮与与与轮胎负载接触的平坦导电表面之间的电阻。 1.2 本试验方法规定了程序和设备，以便能够准确测定值高达10的轮胎的电阻 12 Ω （欧姆）。 1.3 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 在某些情况下，车辆上的静电必须通过轮胎消散。电阻与轮胎耗散车辆静电的能力相反。

1.1 This test method covers the measurement of the electrical resistance between the wheel of a mounted and inflated tire-wheel assembly and a flat conducting surface in loaded contact with the tire. 1.2 This test method specifies procedures and equipment such that electrical resistance can be accurately determined for tires with values up to 10 12 Ω (ohms). 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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. 1.5 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. ====== Significance And Use ====== 5.1 Occasions exist where static charges on the vehicle must be dissipated by way of the tires. Electrical resistance inversely measures the tire's ability to dissipate static charge from the vehicle.
