24、rd ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (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 technic
25、al 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 el
26、ectrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to t
27、he 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 document may be the subject of patent rights. ISO shall not be held responsible for id
28、entifying any or all such patent rights. ISO 5674 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 2, Common tests. This second edition of ISO 5674 cancels and replaces the first editions of ISO 5674-1:1992 and ISO 5674-2:1992, of wh
29、ich it constitutes a technical revision. This corrected version of ISO 5674:2004 incorporates the following corrections or modifications. An error 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 o
30、f 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 system 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, an
31、d “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 Figure D.1. The system of numbering and the wording of D.9 has been altered to avoid possible confusion. EN ISO 5674:2006 Licensed Copy: London South Bank Univ

35、Uncontrolled Copy, (c) BSI 1 Tractors and machinery for agriculture and forestry Guards for power take-off (PTO) drive-shafts Strength and wear tests and acceptance criteria 1 Scope This International Standard specifies laboratory tests for determining the strength and wear resistance of guards for
36、power take-off (PTO) drive-shafts on tractors and machinery used in agriculture and forestry, and their acceptance criteria. It is intended to be used in combination with ISO 5673. It is applicable to the testing of PTO drive-shaft guards and their restraining means. It is not applicable to the test
37、ing of guards designed and constructed to be used as steps. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (i

42、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 design remains the same. When a guard is designed for use with several drive-shaft t
43、ypes, 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 by the manufacturer to be resistant to degradation from UV radiation under an app
44、ropriate, 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 this International Standard. 4.1.4 The guard shall be tested in conjunction with
45、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 drive-shaft shall be revolving, its rotational frequency shall be 1 000 r/min. 4
46、.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. The shafts and guards shall be mount
47、ed as specified for operational use and only fixed by their designated restraining device. The fixing points shall be in accordance with ISO 500 and the equivalent machine standard unless otherwise specified for that type of shaft. The size and shape of the wear test equipment shall be such that an
48、even test environment is maintained, e.g. heat and the dust specified in 5.2.3. 5.1.2 Strength test equipment, which shall allow the accurate application of known loads at controlled temperatures and at the required frequency of rotation within the tolerances stipulated in Table 1. 5.2 Test paramete
49、rs 5.2.1 Measuring accuracy All measurements shall be within the tolerances given in Table 1 except where otherwise required by this International Standard.
