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 organizations, 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees 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. ISO 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. This third edition cancels and replaces the second edition (ISO 1173:1988), which has been technically revised. Annex A of this International Standard is for information only.

It ensures the interchangeability of tool bits and tool holders. This International Standard defines only the distinctive features of individual drive ends. Details of design, e.g. of fixing devices, are left to the user of this International Standard. 2Dimensions See Figures 1 to 8 and Tables 1 to 8. Details not given shall be chosen appropriately.

The same dimensional specifications apply to the test pieces as to the connection parts, however, they do not have to be equipped with a retaining system. The torque test device and the test pieces shall have a hardness of at least HRC 62. 5.2Test 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 deformation or any other damage, such as e.g. cracks or fractures, which might affect the usability of the tool.

When testing with the test torque it shall be ensured that the connecting parts to be tested are engaged under load over their whole lengths l1and l2. The test torque shall be applied smoothly and steadily. Following the application of the minimum test torque, any resulting damage or deformation shall not affect the usability of the tool.

The interchangeability of tool bits and tool holders is ensured by the standardization of the drive ends. To emphasize the relation between the matching dimensions 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 dimensions of the hexagon ends they were calculated according to following formulae: e1 max= 1,13 s1 max e1 min= 1,13 s1 min e2 min= 1,13 s2 min Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/22/2007 08:47:38 MDTNo reproduction or networking permitted without license from IHS -,-,- Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/22/2007 08:47:38 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO 1173:2001(E) ICS 25.140.30 Price based on 8 pages © ISO 2001 All rights reserved Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/22/2007 08:47:38 MDTNo reproduction or networking permitted without license from IHS -,-,-
