Description / Abstract:

These practices cover procedures and requirements for the calibration and verification of displacement measuring systems by means of standard calibration devices for static and quasi-static testing machines. This practice is not intended to be complete purchase specifications for testing machines or displacement measuring systems. Displacement measuring systems are not intended to be used for the determination of strain. See Practice E 83.

These procedures apply to the verification of the displacement measuring systems associated with the testing machine, such as a scale, dial, marked or unmarked recorder chart, digital display, etc. In all cases the buyer/owner/user must designate the displacement-measuring system(s) to be verified.

Since conversion factors are not required in this practice, either SI units, or inch units, can be used as the standard.

Displacement values indicated on displays/printouts of testing machine data systems - be they instantaneous, delayed, stored, or retransmitted - which are within the Classification criteria listed in Table 1, comply with Practices E 2309.

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.
