BS EN ISO 376Metallic materials. Calibration of force-proving instruments used for the verification of uniaxial testing machines
BS EN ISO 376:2011 looks at the calibration of force-proving instruments used for the static verification of uniaxial testing equipment. These include tension and compression testing machines. This standard also defines the classification systems for these instruments. BS EN ISO 376 applies to all force-proving instruments in which the force is determined by measuring the elastic deformation of a loaded member or a quantity that is proportional to it.
