ASTM D1662 – Standard Test Method for Active Sulfur in Cutting Oils
Description:
Significance and Use
5.1 This test method measures the quantity of sulfur available to react with metallic surfaces to form solid lubricating aids at the temperature of the test. Rates of reaction are metal type, temperature, and time dependent.
Scope
1.1 This test method covers the determination of active sulfur in cutting oils. This test method applies to sulfur reactive with copper powder at a temperature of 150 °C (302 °F) in cutting fluids containing both natural and added sulfur.
NOTE 1: It has not been established by ASTM Subcommittee D02.L0 as to how the active sulfur content thus determined may relate to field performance of the cutting fluid.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
