ASTM-D4998 › Standard Test Method for Evaluating Wear Characteristics of Tractor Hydraulic Fluids
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method is used to screen lubricants for gear wear. It is primarily applicable to tractor hydraulic fluids but may be suitable for other applications.
1.2 The values stated in SI units are to be regarded as the 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. Specific hazard information is given in Sections 7 and 9, and Notes 1, 2, 3, 4, and 5.
