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

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
