适用范围

This document specifies a laboratory performance test method for power assembly tools (referred throughout the document as “tool”) for installing threaded fasteners. It provides a method for the measurement of torque repeatability (scatter) — over a range of torque rates as specified in this document, — over a range of torque adjustment as defined by the manufacturer, and — over a number of operating cycles as defined by the manufacturer. It provides a method for the measurement of the precision of the built-in torque measurement system for tools incorporating such a feature. See Annex E. It gives instructions on equipment parameters, what to test for and how to evaluate and present the test data. It is applicable to tools — of any power source, e.g. pneumatic, hydraulic, and electric, including battery-powered, — which apply torque in a generally continuous manner, and — within the torque range 0,5 Nm to 2000 Nm. Outside this range, it is acceptable to modify the test method providing that the modification is documented in the test report. It is not applicable to — impact or impulse wrenches, — ratchet wrenches or wrenches with ratcheting clutches, and — other tools which advance fasteners in discontinuous increments, overcoming static friction at each increment. It allows a test to be performed at any test torque level; however, in order to minimize the number of test joints necessary for a wide range of test torque levels, a list of preferred test torque levels is provided in Annex A.
