1.1This test method covers the determination of the dropping point of lubricating grease.

1.2This test method is not recommended for use at bath temperatures above 288 °C. For higher temperatures Test Method D2265 should be used.

1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4WARNING—This test method uses mercury-filled thermometers. 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 Safety Data Sheet (SDS) 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.G.3, continues to explore alternatives to eventually replace the mercury thermometers.

1.5This standard does not purport to address all of the safety concerns, if any, associated with its use.
