1.1 本试验方法包括测定完全穿透充气轮胎胎面区域所需的轮胎柱塞能量，如破裂、充气压力损失、柱塞力突然下降或底部凹陷所示。该试验需要使用实验室试验机，该试验机能够通过具有半球形端部的柱塞缓慢穿透轮胎的胎面。 1.2 本试验方法适用于通常在道路上使用的车辆的充气轮胎。 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 本试验方法建立了标准试验程序，并提供了与轮胎强度相关的数据，但不测量轮胎性能或制定规范或公差。

1.1 This test method covers the determination of tire plunger energy required to completely penetrate the tread area of an inflated tire as indicated by a rupture, loss of inflation pressure, sudden drop in plunger force or bottom-out. The test requires utilization of a laboratory testing machine capable of slowly penetrating the tread surface of a tire with a plunger having a hemispherical end. 1.2 This test method is applicable to pneumatic tires for vehicles normally used on the road. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided 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 This test method establishes a standard procedure of test and provides data that can be related to tire strength, but does not measure tire performance or establish specification or tolerances.
