1.1 本规范涵盖了汽车或其他轻型服务冷却系统中使用的非水性发动机冷却液的要求。符合规范的非水性冷却剂将有效地防止冻结、沸腾和腐蚀，而无需进一步稀释。本规范基于对由新的工业级二醇单独或混合物制备的非水性发动机冷却剂性能的了解。 1.2 以国际单位制表示的值应被视为标准值。本标准不包括其他计量单位。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。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。 请参阅 X1.4 具体的警告声明。 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。

1.1 This specification covers the requirements for non-aqueous engine coolants used in automobiles or other light-duty service cooling systems. Non-aqueous coolants that conform to the specification will function effectively to provide protection against freezing, boiling, and corrosion without any further dilution. This specification is based upon the knowledge of the performance of non-aqueous engine coolants prepared from new individual or mixtures of virgin industrial grade diols. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. See X1.4 for a specific warning statement. 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.
