2、2006 ISBN 0 580 48495 5 National foreword This Draft for Development reproduces verbatim ISO/TS 21108:2005. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature. It should be applied on thi

3、s provisional basis, so that information and experience of its practical application can be obtained. A review of this Draft for Development will be carried out not later than 2 years after its publication. Notification of the start of the review period, with a request for the submission of comments

4、 from users of this Draft for Development, will be made in an announcement in the appropriate issue of Update Standards. According to the replies received, the responsible BSI Committee will judge whether the Draft for Development can be converted into a British Standard or what other action should

5、be taken. Observations which it is felt should receive attention before the official call for comments will be welcomed. These should be sent to the Secretary of BSI Technical Committee MCE/8, Compressors, pneumatic tools, pneumatic machines and vacuum technology, at British Standards House, 389 Chi

The work of pr

11、eparing 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 represented on that committee. International organizations, governmental and non-governmental, i

12、n liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main tas

13、k of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other

14、 circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and i

15、s accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members o

16、f the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three y

17、ears, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

DD ISO/TS 21108:2005 iv Introduction When power sockets for hand-held pulse wrenches are centred on the cylindrical surface of the spind

19、le, several advantages are achieved. Through this centred engagement vibrations and wobbling are reduced, in turn reducing the risk for injury and improving operator ergonomics, torque accuracy is increased, improving the quality of the production, and energy loss is reduced, saving energy. The vari

20、ety of dimensions on the spindle diameter has created a need for standardization of the interface between these pulse tools and power sockets. Because of the existence of differently designed impulse wrenches, the need for two options, A and B, for the series of values for the spindle and the intern

21、al socket diameters, has also been perceived. This document has been published as a technical specification (see Foreword) in order to discourage the development of yet more designs, and enable the usage of each of the two series to be monitored, with the eventual aim of standardizing one of them. 1

22、 Hand-held power tools Impulse wrenches Dimensions and tolerances of interface to power socket 1 Scope This Technical Specification specifies the dimensions and tolerances for the interface between impulse wrenches and their power sockets: output spindle of power toolfemale drive end of power socket

23、. This interface is based on the principle of a socket centred on the cylindrical spindle. Alternative dimensions and tolerances for two options, A and B, are provided. It is applicable to both pneumatically and electrically driven impulse tools, and could also be used in other applications. 2 Terms

24、 and definitions For the purposes of this document, the following terms and definitions apply. 2.1 female drive end part of a power socket at which the spindle of a power tool is attached 2.2 male spindle end cylindrical and square part of the spindle of a power tool 2.3 power socket part for the tr
