(Test Method)Standard Test Method for Comparing Metal Removal Fluids Using the Tapping Torque Test Machine (Withdrawn 2016)
Standard Test Method for Comparing Metal Removal Fluids Using the Tapping Torque Test Machine (Withdrawn 2016)
SIGNIFICANCE AND USE
The procedures described in this test method can be used to predict more accurately the lubricating properties of a metal removal fluid than previously available laboratory scale tests.
This test method is designed to allow flexibility in the selection of test specimen metal composition, tap alloy or coatings, and machining speeds.
Comparison between various types of fluids can be made, including cutting oils, soluble oils, semi-synthetics, or water soluble synthetics.
SCOPE
1.1 This test method covers a laboratory technique to evaluate the relative performance of metal removal fluids using a non-matrix test protocol using the tapping torque test machine.
1.2 The values stated in SI units are to be regarded as standard. Because the equipment used in this test method is available only in inch-pound units, SI units are omitted when referring to the equipment and the test pieces.
1.3 This test method 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.
WITHDRAWN RATIONALE
This test method covers a laboratory technique to evaluate the relative performance of metal removal fluids using a non-matrix test protocol using the tapping torque test machine.
Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this test method was withdrawn in January 2016. This standard was withdrawn without replacement due to lack of interest in supporting the standard with updated/compliant precision information.
