Standard Test Method for Percent Ash Content of Engine Coolants 发动机冷却剂灰分含量百分比的标准试验方法
发布日期: 2022-03-01
1.1 本试验方法涵盖了商用发动机冷却液和防锈剂(包装或使用后)点火后灰分含量的测定。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 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。 具体警告声明见 7.1 和 7.3 . 1.4 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 本试验方法旨在帮助识别冷却液的类型。虽然灰分主要是由于使用了无机抑制剂,但由于有机抑制剂的损失,灰分不是抑制剂总浓度的衡量标准。 5.2 灰分含量大于规范中规定的灰分含量 D3306 可能表示盐基产品。
1.1 This test method covers the determination of ash content after ignition of commercial engine coolants and antirusts, as packaged or after use. 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. Specific warning statements are given in 7.1 and 7.3 . 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 is designed to aid in identifying types of coolants. While the ash is primarily due to the inorganic inhibitors used, it is not a measure of the total inhibitor concentration because of the loss of organic inhibitors. 5.2 An ash content greater than that stated in Specification D3306 may indicate a salt-based product.
