The work
29、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-government
30、al, 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 2. The mai
31、n task of technical committees is to prepare International Standards. 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. Att
32、ention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

This corrected version of ISO 5674:2004 incorporates the following corrections or modifications. An erro
34、r in the second column heading of Table 2 (“m/m”) has been eliminated. Figure 1 has been modified, and numbering of elements and a key added. The wording of the third sentence of 6.5.2 has been changed. The title of 6.6 has been corrected from “specified temperature” to “ambient temperature”. The sy
35、stem of numbering and the wording of A.1 has been altered to avoid possible confusion. Figure A.1 has been changed to show the blows at three locations, and “h” has been deleted from the drawing and the legend as a result of the change to 6.5.2. Cross-references have been added to the legend to Figu

45、ISO 2004 All rights reserved4 General test conditions 4.1 Guard 4.1.1 The guard shall be representative of a production model and be within the tolerances specified for the guard. The results obtained from the sample can be used to certify guards of shorter or longer lengths, provided the basic desi
46、gn remains the same. When a guard is designed for use with several drive-shaft types, a representative selection of shaft and guard combinations shall be tested. 4.1.2 If the guard is made of plastic material (or any other material susceptible to degradation by UV radiation), it shall be certified b
47、y the manufacturer to be resistant to degradation from UV radiation under an appropriate, recognized method. See Annex B for an example. 4.1.3 During testing, all operating and maintenance instructions specified for the shaft and guard shall be complied with, except where specifically mentioned by t
48、his International Standard. 4.1.4 The guard shall be tested in conjunction with a PTO drive-shaft of between 900 mm and 1 010 mm closed length for which it is intended. The same guard shall be used throughout all the tests. 4.2 Other 4.2.1 Where specified in this International Standard that the PTO
49、drive-shaft shall be revolving, its rotational frequency shall be 1 000 r/min. 4.2.2 All tests shall be carried out in accordance with the schedule and in the sequence given in Annex A. 5 Test equipment 5.1 General 5.1.1 Wear test equipment, which shall be capable of holding the PTO drive-shaft and revolving it at a frequency of 1 000 r/min.
