Metallic materials - Calibration of extensometers used in uniaxial testing (ISO 9513:1999) (Austrian Standard)
This International Standard specifies a method for the static calibration of extensometers used in uniaxial testing.
The term “extensometer” is understood to mean the displacement measuring device and the system for indicating or recording this displacement.
Special consideration should be given to such devices. These issues should be addressed at the next revision of this International Standard. However some guidance on this subject might be found in ASTM E83:1996 (see Bibliography).
