1.1 本试验方法包括润滑脂滴点的测定。 1.2 本试验方法使用水银温度计。 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EPA网站-http://www.epa.gov/mercury/faq.htm-了解更多信息。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。 负责小组委员会，D02。G0.03，继续探索最终取代水银温度计的替代品。 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。 ====意义和用途====== 5.1 滴点有助于识别润滑脂的类型，并有助于建立和维护质量控制基准。由于滴点是静态测试，因此，结果对服务性能的意义有限。 5.2 协同测试 3. 表明，通常情况下，通过测试方法确定的下降点 D2265 和试验方法 D566 最多260个 °C.在结果不同的情况下，没有已知的意义。但是，制造商和买方之间应就所用试验方法达成一致。

1.1 This test method covers the determination of the dropping point of lubricating grease. 1.2 This test method uses mercury thermometers. 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. The responsible subcommittee, D02.G0.03, continues to explore alternatives to eventually replace the mercury thermometers. 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. ====== Significance And Use ====== 5.1 The dropping point is useful to assist in identifying the grease as to type and for establishing and maintaining bench marks for quality control. The results are to be considered to have only limited significance with respect to service performance because dropping point is a static test. 5.2 Cooperative testing 3 indicates that, in general, dropping points by Test Method D2265 and Test Method D566 are in agreement up to 260 °C. In cases where results differ, there is no known significance. However, agreement between the manufacturer and purchaser as to test method used is advisable.
