The UK participation in its preparation was entrusted by Technical Committee MTE/15, Hand tools, to Subcommittee MTE/1
3、5/13, Spanners and screwdrivers, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and Euro
4、pean developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI St

11、 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 represented on that committee. International organiza
12、tions, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circu
13、lated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO 10914 was prepared by Technical Committee ISO/TC29, Small tools, Subcommittee SC 10, Assembly tools for screws and nuts, pl
14、iers and nippers. Descriptors: Tools, assembly tools, hand tools, wrenches, socket wrenches, classification, specifications, dimensions, designat marking, interchangeability.BSISO10914:1996 BSI 04-1999 1 1 Scope This International Standard specifies the technical, dimensional and test requirements f
15、or hand-operated sockets and box wrenches used for the attachment and detachment of metric spline drive fasteners according to ISO7403. It applies to tools listed in the classification of clause3. This type of tool is mainly used in the aeronautic industry. The overall dimensions are not in accordan
16、ce with other International Standards relating to dimensions. NOTEThe figures in this International Standard are descriptive, not restrictive, and are not intended to exclude any sockets and box wrenches provided they be in accordance with this International Standard. 2 Normative references The foll
17、owing standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are enc
18、ouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.
