D7452-08 Standard Test Method for Evaluation of the Load Carrying Properties of Lubricants Used for Final Drive Axles, Under Conditions of High Speed and Shock Loading
| Published By | Publication Date | Number of Pages |
| ASTM | 2008 | 22 |
1.1 This test method covers the determination of the anti-scoring properties of final drive axle lubricating oils when subjected to high-speed and shock conditions. This test method is commonly referred to as the L-42 test.
1.2 The values stated in foot-pound units are to be regarded as standard. For example, torque is stated in foot-pound units, the values for temperature are stated in degrees Fahrenheit, and the test lubricant sample volume is stated in pints. The values given in parentheses are mathematical conversions to SI units that are provided for information purposes only, and are not considered standard. SI units are provided for all parameters except where there is no direct equivalent such as the units for screw threads, national pipe threads/diameters, and tubing size.
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 warning information is given in Sections 4 and 7.
