Standard Test Method for Determining Extreme Pressure Properties of Solid Bonded Films Using a High-Frequency, Linear-Oscillation (SRV) Test Machine
SIGNIFICANCE AND USE
5.1 This laboratory test method can be used to quickly determine extreme pressure properties of parts coated with solid bonded films at selected temperatures specified for use in unlubricated applications where high-speed vibrational or start-stop motions are present with high Hertzian point contact. This test method has found wide application in qualifying solid bonded films used in automotive door lock mechanisms, hinge joints, bolts, and in aerospace. This test method is a material and application oriented approach for characterizing the tribological behaviour using random, discrete and constant parameter combinations. Users of this test method should determine whether results correlate with field performance or other applications.
SCOPE
1.1 This test method covers a procedure for determining extreme pressure properties of solid bonded films under high-frequency linear-oscillation motion using the SRV test machine.
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.
