1.1 本试验方法涵盖了通过冷却速率测定评估水性聚合物淬火剂淬火特性的设备和程序的说明。 1.2 本试验方法旨在评估在非搅拌系统中用于钢合金的水性聚合物淬火剂。这些测试结果与在搅拌系统中获得的结果之间没有相关性。 1.3 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.4 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。 1.5 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 该测试方法提供了冷却时间与温度的关系曲线。通过该试验方法获得的结果可作为淬火剂选择或不同淬火剂（新的或使用过的）淬火严重程度比较的指南。

1.1 This test method covers the description of the equipment and the procedure for evaluating quenching characteristics of aqueous polymer quenchants by cooling rate determination. 1.2 This test method is designed to evaluate aqueous polymer quenchants for steel alloys in a non-agitated system. There is no correlation between these test results and the results obtained in agitated systems. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 provides a cooling time versus temperature pathway. The results obtained by this test method may be used as a guide in quenchant selection or comparison of quench severities of different quenchants, new or used.
