1.1 本试验方法包括一个简单的烧杯型程序，用于在受控的实验室条件下评估发动机冷却剂对金属样品的影响（见 附录X1 ). 注1: 有关发动机冷却液的更多信息，请参见（参考 1. 8. ) . 2. 1.2 以国际单位制表示的数值应视为标准。SI单位后括号中给出的值仅供参考，不被视为标准值。 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。 具体危害说明见 11.1.7.2 , 11.1.7.3 和 11.1.7.4 . 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》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 该试验方法通常会区分从腐蚀角度来看肯定有害的冷却剂和适合进一步评估的冷却剂。然而，该试验方法的结果不能单独作为令人满意的缓蚀作用的证据。发动机冷却液配方的实际使用值只能通过更全面的台架、测功机和现场测试来确定。

1.1 This test method covers a simple beaker-type procedure for evaluating the effects of engine coolants on metal specimens under controlled laboratory conditions (see Appendix X1 ). Note 1: For more information on engine coolants, see (Refs 1- 8 ) . 2 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 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. Specific hazard statements are given in 11.1.7.2 , 11.1.7.3 , and 11.1.7.4 . 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 This test method will generally distinguish between coolants that are definitely deleterious from the corrosion standpoint and those that are suitable for further evaluation. However, the results of this test method cannot stand alone as evidence of satisfactory corrosion inhibition. The actual service value of an engine coolant formulation can be determined only by more comprehensive bench, dynamometer, and field tests.
