ASTM D7043-17

Standard Test Method for Indicating Wear Characteristics of Non-Petroleum and Petroleum Hydraulic Fluids in a Constant Volume Vane Pump

SIGNIFICANCE AND USE
5.1 This test method is an indicator of the wear characteristics of non-petroleum and petroleum hydraulic fluids operating in a constant volume vane pump. Excessive wear in vane pumps could lead to malfunction of hydraulic systems in critical applications.
SCOPE
1.1 This test method covers a constant volume vane pump test procedure operated at 1200 r/min and 13.8 MPa.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.2.1 Exception—There are no SI equivalents for the inch fasteners and inch O-rings that are used in the apparatus in this test method.  
1.2.2 Exception—In some cases English pressure values are given in parentheses as a safety measure.  
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.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Summary of Test Method
4.1 An amount of 18.9 L 6 0.5 L of a hydraulic fluid are circulated through a rotary vane pump system for 100 h at a pump
speed of 1200 r ⁄min 6 60 r ⁄min and a pump outlet pressure of 13.8 MPa 6 0.3 MPa (2000 psi 6 40 psi). Fluid temperature at
the pump inlet is 66 °C 6 3 °C for all water glycols, emulsions, and other water containing fluids and for petroleum and synthetic
fluids of ISO Grade 46 or lighter. A temperature of 80 °C 6 3 °C is used for all other synthetic and petroleum fluids.
4.2 The result obtained is the total mass loss from the cam ring and the twelve vanes during the test. Other reported values are
initial flow rate and final flow rate.
