Active Standard ASTM E2428 | Developed by Subcommittee: E28.01
Book of Standards Volume: 03.01
Significance and Use
Testing machines that apply and indicate torque are in general use in many industries. Practice WK6364
1.1 This practice is to specify procedure for the calibration of elastic torque-measuring instruments.
Note 1—Verification by deadweight and a lever arm is an acceptable method of verifying the torque indication of a torque testing machine. Tolerances for weights used are tabulated in Practice WK6364
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 This practice is intended for the calibration of static or quasi-static torque measuring instruments. The practice is not applicable for high speed torque calibrations or measurements.
1.4 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.
