10、dies (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 organizatio
11、ns, 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.The procedures used to develop this document and those intended for its further
12、 maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives)

17、 nominal widths across flats not covered by ISO 272; Table 2 was removed and the torque testing was substituted with a reference to ISO 1711-1.1 ScopeThis document specifies requirements of single-head engineers wrenches with nominal width across flats from 3,2 to 120.It specifies the maximum outsid
18、e dimensions of heads and gives the test torque values. The “lower torque application” designation is in accordance with the smaller head dimensions.NOTE The wrenches covered by this document are the ones identified in ISO 1703:2005 under reference Nos. 1 1 01 01 0 and 1 1 01 01 1.
