1.1 本规程给出了以下校准程序: 参考称重传感器 使用参考称重传感器校准平台系统 通过使用校准平台系统作为校准夹具，对轮胎试验拖车、仪表车辆和实验室轮胎试验机锁定车轮上的制动/牵引力进行静态校准。 1.2 以国际单位表示的值应视为标准值。括号中的值仅供参考。 1.3 本标准并不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建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 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》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 在使用各种测试平台和设备时，校准至关重要，以确保这些测试设备生成的测试结果准确、可重复且有意义。本标准给出了校准范围中引用的所有试验装置的必要说明。

1.1 This practice gives procedures for the calibration of: reference load cells calibration platform systems by using a reference load cell static calibration of braking/tractive force on locked wheels of tire test trailers, instrumented vehicles, and laboratory tire testing machines by using the calibration platform system as a calibration fixture. 1.2 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only. 1.3 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. 1.4 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 Calibration is essential in the use of various test platforms and devices to insure that the test results generated by these test devices are accurate, repeatable and meaningful. This standard gives the necessary instructions for the calibration of all of the test devices cited in the Scope.
