Size: 132 kBScope1.1 These practices cover procedures for the force
verification, by means of standard calibration devices, of
tension or compression, or both, static or quasi-static testing
machines (which may, or may not, have force-indicating
systems). These practices are not intended to be complete
purchase specifications for testing machines. Testing machines
may be verified by one of the three following methods or
combination thereof:1.1.1 Use of standard weights,
1.1.2 Use of equal-arm balances and standard weights, or
1.1.3 Use of elastic calibration devices.NOTE 1—These practices do not cover the verification of all types of
testing machines designed to measure forces, for example, the constantrate-
of-loading type which operates on the inclined-plane principle. This
type of machine may be verified as directed in the applicable appendix of
Specification D76.
