1.1 本试验方法包括测定−36以下原油倾点温度的两个程序 °C。步骤A提供了最高（上）倾点温度的测量值，如中所述 9.1 程序B提供了最低（较低）倾点温度的测量值，并在中进行了描述 9.2 . 1.2 本试验方法仅限于用于原油。其他石油产品的倾点温度可通过试验方法确定 D97 . 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 警告 --汞已被许多监管机构指定为一种可能导致严重医疗问题的危险物质。汞或其蒸汽已被证明对健康有害，对材料具有腐蚀性。处理汞和汞时要小心- 含有产品。有关更多信息，请参阅适用的产品安全数据表（SDS）。当地或国家法律有可能禁止销售汞或含汞产品，或两者兼而有之。用户必须确定在其所在地销售的合法性。 1.5 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。 有关具体的危险说明，请参阅第节 7. . 1.6 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 原油的倾点是某些应用中可处理性的最低温度的指标。 5.2 这是唯一专门为原油设计的倾点法。 5.3 最高和最低倾点温度提供了一个温度窗口，根据原油的热历史，原油可能出现在液体和固体中。 5.4 该测试方法可用于补充冷流行为的其他测量。这对于筛选蜡相互作用改性剂对原油流动行为的影响尤其有用。

1.1 This test method covers two procedures for the determination of the pour point temperatures of crude oils down to −36 °C. Procedure A provides a measure of the maximum (upper) pour point temperature and is described in 9.1 . Procedure B provides a measure of the minimum (lower) pour point temperature and is described in 9.2 . 1.2 The use of this test method is limited to use for crude oils. Pour point temperatures of other petroleum products can be determined by Test Method D97 . 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 WARNING —Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location. 1.5 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. For specific hazard statements, see Section 7 . 1.6 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 The pour point of a crude oil is an index of the lowest temperature of handleability for certain applications. 5.2 This is the only pour point method specifically designed for crude oils. 5.3 The maximum and minimum pour point temperatures provide a temperature window where a crude oil, depending on its thermal history, might appear in the liquid as well as the solid state. 5.4 The test method can be used to supplement other measurements of cold flow behavior. It is especially useful for the screening of the effect of wax interaction modifiers on the flow behavior of crude oils.
