1.1 本试验方法包括测定石油蜡（包括矿脂）的凝固点。 1.2 以国际单位制表示的数值应视为标准。 1.2.1 例外情况- 括号中给出的值仅供参考。 1.3 警告 -许多监管机构已将汞指定为一种有害物质，可导致中枢神经系统、肾脏和肝脏损伤。汞或其蒸汽可能对健康有害，并对材料具有腐蚀性。处理汞和含汞产品时应小心。有关详细信息，请参阅适用的产品材料安全数据表（MSDS）和美国环保局网站http: //www.epa。gov/mercury/faq。htm以获取更多信息。用户应意识到，法律可能禁止向您所在的州或国家销售汞和/或含汞产品。 1.4 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和健康实践，并确定监管限制的适用性。 注1: 本试验方法是试验方法的替代方法 D127 . 获得的结果通常低于通过试验方法获得的结果 D127 – IP 偏差量随石油蜡的性质而变化。 1.5 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 凝点是许多石油蜡消费者感兴趣的蜡特性。此处描述的程序测量正在冷却的样品产生“凝固”或流动阻力的温度。 在该温度下，蜡可能处于或接近固态，也可能是半固态且非常粗糙，这取决于所测试蜡或矿脂的成分。就矿脂而言，当样品冷却时，凝结性能与凝胶结构的形成有关。

1.1 This test method covers determination of the congealing point of petroleum waxes, including petrolatum. 1.2 The values stated in SI units are to be regarded as the standard. 1.2.1 Exception— The values given in parentheses are for information only. 1.3 WARNING —Mercury has been designated by many regulatory agencies as a hazardous material that can cause central nervous system, kidney and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA’s website—http://www.epa.gov/mercury/faq.htm—for additional information. Users should be aware that selling mercury and/or mercury containing products into your state or country may be prohibited by law. 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 and health practices and determine the applicability of regulatory limitations prior to use. Note 1: This test method is an alternative to Test Method D127 . Results obtained are usually lower than the results obtained by Test Method D127 – IP 133, the amount of the deviation varying with the nature of the petroleum wax. 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 Congealing point is a wax property that is of interest to many petroleum wax consumers. The procedure described here measures the temperature at which a sample being cooled develops a “set” or resistance to flow. At that temperature, the wax may be at or close to the solid state, or it may be semisolid and quite unctuous, depending on the composition of the wax or petrolatum being tested. In the case of petrolatums, congealing property is associated with the formation of a gel structure as the sample cools.
