This part of ISO 7500 specifies the verification of tension/compression testing machines. The verification consists of: - a general inspection of the testing machine, including its accessories for the force application; - a calibration of the force-measuring system. NOTE This part of ISO 7500 addresses the static verification of the force-measuring systems and the calibration values are not necessarily valid for high-speed or dynamic testing applications. Further information regarding dynamic effects is given in the Bibliography.
