Description

ASTM D3520-04

Historical Standard: Standard Test Method for Quenching Time of Heat-Treating Fluids (Magnetic Quenchometer Method) (Withdrawn 2008)

ASTM D3520

Scope

1.1 This test method covers a procedure for making a comparative evaluation of the quenching speed characteristics of petroleum fluids used in the quenching of metals by means of the Magnetic Quenchometer.

Note 1—A comparison method for testing the hardenability of steel is Test Method A 255.

Note 2—An additional comparison method for evaluation of the quenching speed characteristics of petroleum fluids used in the quenching of metals is Test Method D 6200.

1.2 This test method provides a measure of changes in oil chemistry due to contamination, base oil degradation, and additive drag-out during use. This test measures changes in the quenching speed characteristics of petroleum fluids at the high temperature (>354°C). This test method does not reliably predict metallurgical performance.

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 requirements prior to use.
