ISO (the International Organization for Standardization) is a worldwide federation or national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be reprented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates cloly with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures ud to develop this document and tho intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the di
fferent types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (e www.iso/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not held responsible for identifying any or all such patent right.

Introduction
The test method specified in this document is designed to measure the performance of power asmbly tools in a laboratory environment, it is not intended as a routine in-plant inspection test.
This document is intended
-To enable the producers of power tools to offer their products under standardized technical specifications, and
-To give urs of threaded fasteners a method for evaluating and specifying the performance of power asmbly tools.
As with the previously published versions, this 2017 version of the document remains a fundamental test procedure, with no attempt to t acceptance criteria. Any minimum performance requirements are responsibility of the urs to meet the demands of the particular application for which the tool is intended for u.陀螺图片大全

This version includes some changes to the specifications for the test joints and for the test method. The changes reflect the practical experience gained through the u of the document and are intended to improve the reproducibility of the test method. Result obtained using this version is not expected to be significantly different than result obtained using the previous version.
Information regarding rated torque, test torque and torque adjustment range: The scope (e last paragraph) allows a test to be performed at any test torque level (e 3.18). a manufacturer defines a tool’s rated torque (e 3.11) and its torque adjustment range (e 3.21). Clau 6 describes a method to identify torque scatter over a defined range of torque adjustment. In theory, a manufacturer could offer a tool with a defined rated torque of 100 Nm, and may choo to identify the performance over a defined torque adjustment range of 60 Nm to 80 Nm (perhaps to satisfy a customer or market requirement). In that ca, as specified in Clau 6, performance tests will be carried out at 60 Nm and 80 Nm, and should the manufacturer want to identify the tool’s performance over a defin ed number of operating cycles, the operating cycle test would be performed at 80 Nm (the upper limit of the defined range of torque adjustment, as specified in 7.2.2). Results of the performance tests would then be valid only for that defined range of torque adjustment.
1Scope
This document specifies a laboratory performance test method for power asmbly tools (referred throughout the document as “tool”) for installing threaded fasteners.
It provides a method for the measurement of torque repeatability (scatter)
阀体材料-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 prent 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 2 000 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 impul wrenches,
-Ratchet wrenches or wrenches with ratcheting clutches, and
-Other tools which advance fasteners in discontinuous increments, overcoming static friction at each increment.
健康的副词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.
