Abstract

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. The apparatus for verifying extensometer systems shall provide a means for applying controlled displacements to a simulated specimen and for measuring these displacements accurately. Extensometer systems shall be classified in accordance with the requirements as to maximum error of strain indicated: Class A; Class B-1; Class B-2; Class C; Class D; and Class E. Extensometer systems shall be categorized in three types according to gage length: Type 1; Type 2; and Type 3. A verification procedure for extensometer systems shall be done in accordance with the specified requirements.
