Resumen:
ISO 6789-2 specifies the method for the calibration of hand torque tools and describes the method of calculation of measurement uncertainties for the calibration. Annex C specifies the minimum requirements for the calibration of the torque measuring instrument where the maximum relative measurement uncertainty interval is not already established according to ISO/IEC 17025. It is applicable for the progressive (static) and continuous (quasi-static) calibration of torque measuring instruments, the torque of which is defined by measuring of the elastic form change of a deformable body or a measured variable which is in proportion to the torque. ISO 6789-2 provides information for calibration of these torque tools by calibration laboratories operating in accordance with ISO/IEC 17025 and by calibration facilities of users. It applies to torque tools in accordance with Clause 4, in particular to indicating torque tools (Type I) and setting torque tools (Type II) in accordance with ISO 1703:2005, designations 6100110, 6100111 and 6100120, 6100121 (old numbers 258 and 259).
