The work of preparing International Standards is normally carr

10、ied 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, in liaison with ISO, also take part in the work.

11、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 3. Draft International Standards adopted by the technical commi

12、ttees 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. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. I

13、SO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 1173 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 10, Assembly tools for screws and nuts, pliers and nippers.

31、orque testing 5.1 Test piece For torque testing, test devices shall be used which correspond in their dimensions to the respective “counterbodies“ of the connecting parts to be tested. The same dimensional specifications apply to the test pieces as to the connection parts, however, they do not have

32、to be equipped with a retaining system. The torque test device and the test pieces shall have a hardness of at least HRC 62. 5.2 Test values The test torque values for torque testing are given in Table 9. Following the application of the test torque the connecting parts shall show no permanent defor

33、mation or any other damage, such as e.g. cracks or fractures, which might affect the usability of the tool. Table 9 Test torque values Nominal dimension Test torque a min.

Following the application of the minimum test torque, any resulting damage or deformation shall not affect the usability of the tool.ISO 1173:2001(E) 8 Annex A (informative) Explanatory notes In the case of screwdr

36、iver bits and driving spindles of electric and pneumatic screwdrivers driving is performed by hexagon connection or a flat end connection. The interchangeability of tool bits and tool holders is ensured by the standardization of the drive ends. To emphasize the relation between the matching dimensio

37、ns of male and female hexagons or male and female flat ends respectively, this International Standard has been editorially designed such that dimensional letters for male parts have only uneven subscripts (1, 3, 5 .) and for female parts even subscripts (2, 4, 6 .). In order to coordinate the corner

38、 dimensions of the hexagon ends they were calculated according to following formulae: e 1ma x =1,13s 1ma x e 1min =1,13s 1min e 2min =1,13s 2minBS ISO 1173:2001 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent national body responsible for preparing B
