ASTM D1662-07
(Test Method)Standard Test Method for Active Sulfur in Cutting Oils
Standard Test Method for Active Sulfur in Cutting Oils
SIGNIFICANCE AND USE
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 150C (302F) in cutting fluids containing both natural and added sulfur. Note 1It 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 &si-value;
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.
