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,

12、 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 circulated

13、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 ISO11168 was prepared by Technical Committee ISO/TC29, Small tools, Subcommittee SC10, Spanners and wrenches. Annex A of this Interna

14、tional Standard is for information only.iv blankISO11168:1995(E) BSI 02-2000 1 1 Scope This International Standard specifies the dimensions and the technical requirements for socket wrenches for spark- and glow-plugs. The wrenches described in the present International Standard are for hand operatio

15、n and are designed to drive spark and glow diesel plugs with hexagon drive. 2 Normative references The following 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. Al

16、l standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

20、SI 02-2000 4 Drive The wrenches described in the present International Standard must be provided with an adequate drive system, which can be made of one of the following shapes or their combinations: shape I: female square drive according to ISO1174; shape II: male hexagon drive for wrench opening a

21、ccording to ISO691 having a size not lower than “s”; shape III: hole with insertable tommy bar; shape IV: fork for joint connection; shape V: all other shapes admitted. The symbol of the shape must be stated in the designation; for shapesI andII, the symbol must also include the characteristics defi

22、ned in ISO1174 and ISO691. The size of drives for shapesIII, IV andV are left to the manufacturers discretion. 5 Retaining system The wrenches described in this International Standard can be fitted with an adequate spark-plug retaining system. In such a case the spark-plug must release under a tract

23、ion force of between5N and30N. The retaining system shall avoid any damage to the spark-plug insulator. For certain devices, the internal diameter of this device can be less than the diameter d 2given in Table 1. 6 Torque testing Place the tool in a hexagon test mandrel and apply the corresponding m

24、inimum torque indicated in Table 2. This test shall be carried out using a hexagon test mandrel with minimum hexagon size and minimum dimensions across corners given in the corresponding International Standards, covering spark and/or glow plugs (see Annex A). The hexagon test mandrel shall be harden

25、ed to not less than55HRC. The depth of penetration of the hexagon mandrel into the tool shall be4mm. Following the application of the minimum test torque, any possible damage or deformation shall not affect usability of the socket wrench. 7 Designation A socket wrench for spark- and glow-plugs confo

26、rming to the present International Standard shall be designated as follows: a) “plug wrench”; b) reference to this International Standard (i.e.ISO11168); c) width across flats, s, in millimetres; d) the symbol of the shape of the drive system with, for shapesI andII, the drive dimensions.
