This International Standard covers the calibration of force-proving instruments used for the static verification of
uniaxial testing machines (e.g. tension/compression testing machines) and describes a procedure for
classifying these instruments.
This International Standard generally applies to force-proving instruments in which the force is determined by
measuring the elastic deformation of a loaded member or a quantity which is proportional to it.
