BS EN ISO 7500-1:2018 specifies the calibration and 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 of the testing machine;
—a confirmation that the performance properties of the testing machine achieve the limits given for a specified class.
NOTE :This document addresses the static calibration and verification of the force-measuring systems. The calibration values are not necessarily valid for high-speed or dynamic testing applications. Further information regarding dynamic effects is given in the Bibliography.
The calibration shall be carried out using force-proving instruments with the following exception: if the force to be verified is below the lower limit of the smallest capacity force-proving device used in the calibration procedure, use known masses.
