The guideline defines a procedure for the evaluation and specification of the efficiency of strength-operated assembly tools for threaded fastening elements. The defined procedure will enable manufacturers of power and manually operated tools to offer their products under correlated technical specifications. The guideline specifies a laboratory performance test method. It gives instructions about what and how to test and how the test data are to be evaluated and be presented. The guideline is valid for tools with an operating range of typically 0,5 Nm to 1 kNm which produce a continuous torque curve and also for production tools (measuring torque wrenches for use on the production line).
