ASTM D6203-06(2012)
(Test Method)Standard Test Method for Thermal Stability of Way Lubricants
Standard Test Method for Thermal Stability of Way Lubricants
SIGNIFICANCE AND USE
Thermal stability characterizes physical and chemical property changes which may adversely affect an oil's lubricating performance. This test method evaluates the thermal stability of a way lubricant in the presence of copper and steel rods at 100°C. Deposits and rod colors are the evaluation criteria. No correlation of the test to field service has been made.
This test method is intended for use in qualifying a way lubricant, rather than for quality control or condition monitoring purposes.
SCOPE
1.1 This test method covers the evaluation of the thermal stability of hydrocarbon–based way lubricants, although oxidation may occur during the test.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.3 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.
