Historical Standard: ASTM E83-02 Standard Practice for Verification and Classification of Extensometer System
SUPERSEDED (see Active link, below)
ASTM E83
1. Scope
1.1 This practice covers procedures for the verification and classification of extensometer systems, but it is not intended to be a complete purchase specification. The practice is applicable only to instruments that indicate or record values that are proportional to changes in length corresponding to either tensile or compressive strain. Extensometer systems are classified on the basis of the magnitude of their errors.
1.2 Because strain is a dimensionless quantity, this document can be used for extensometers based on either SI or US customary units of displacement.
Note 1Bonded resistance strain gages directly bonded to a specimen cannot be calibrated or verified with the apparatus described in this practice for the verification of extensometers having definite gage points. (See procedures as described in Test Methods E251.)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 limitations prior to use.
