1 Scope 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 t...
