This document specifies the conformance testing and marking requirements for hand torque tools used for controlled tightening of screws and nuts. It also specifies the minimum requirements for a manufacturer’s declaration of conformance for hand torque tools. This document applies to hand torque tools which are classified as indicating torque tools (Type I) and setting torque tools (Type II). NOTE         Hand torque tools covered by this document are those identified in ISO 1703:2018 by reference numbers 7 1 00 01 0 to 7 1 00 14 0 inclusive. Torque limiting hand torque tools do not yet have reference numbers and will not do so until the next revision of ISO 1703 This document does not specify requirements of calibration certificates for hand torque tools. These are described in ISO 6789‑2. This document does not specify requirements for verifying the performance of hand torque tools. These are described in ISO 6789-3.

This document specifies the method for the calibration of hand torque tools and describes the method of calculation of measurement uncertainties for the calibration. It also specifies the minimum requirements for a certificate of calibration to this standard for hand torque tools. The Annex C of this document specifies the minimum requirements for the calibration of the torque measurement device where the relative measurement uncertainty interval, W´md, is not already provided by a traceable calibration certificate. This document applies to hand torque tools which are classified as indicating torque tools (Type I) and setting torque tools (Type II). NOTE  Hand torque tools covered by this document are those identified in ISO 1703:2018 by reference numbers 7 1 00 01 0 to 7 1 00 14 0 inclusive. Torque limiting hand torque tools do not yet have reference numbers and will not do so until the next revision of ISO 1703
