Standard Test Method for Thermal Stability of Hydraulic Oils — 4 стр.
Значение и использование

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 hydraulic oil in the presence of copper and steel at 135°C. Rod colors are the evaluation criteria. Sludge values are reported for informational purposes. No correlation of the test to field service has been made.

Область применения

1.1 This test method is designed primarily to evaluate the thermal stability of hydrocarbon based hydraulic oils although oxidation may occur during the test.

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

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.
