4、74:2007-04 may be used in parallel until 28 December 2009. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee ISO/TC 23 “Tractors and machinery for agriculture and forestry” in collaboration with Technical Committee CEN/TC 144 “Tracto
5、rs and machinery for agriculture and forestry” (Secretariat: AFNOR, France). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Section Landtechnik. Amendment of the European Machinery Directive has made it neces
6、sary to review the previously valid standard, EN ISO 5674:2006, in terms of the essential requirements of the new European Machinery Directive, 2006/42/EC. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC (va
7、lid until 28 December 2009), and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to guards for power take-off (PTO) drive-shafts that are either first placed on the market or commissioned within the EEA. This standard serves to facilit
8、ate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Dire
9、ctive (“presumption of conformity”). The International Standards referred to in clause 2 of this document have been published as the corresponding DIN EN ISO Standards with the same number, except for those below, which correspond as follows: ISO 105-A02 DIN EN 20105-A02:1994 ISO 500 (all parts) no

11、/37/EC” has been updated. b) Annex ZB (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC” has been added. ISO 5674:2004, corrected (English) version 2005-07-01, includes the following amendments: a) An error in the second column headi
12、ng of Table 2 (“m/m”) has been eliminated. b) Figure 1 has been modified, and numbering of elements and a key added. c) The wording of the third sentence of 6.5.2 has been changed. d) The title of 6.6 has been corrected from “specified temperature” to “ambient temperature”. e) The system of numberin
13、g and the wording of A.1 have been altered to avoid possible confusion. f) Figure A.1 has been changed to show the blows at three locations, and “h” has been deleted from the drawing and the key as a result of the change to 6.5.2. g) Cross-references have been added to the key to Figure D.1. h) The

40、ified 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 types, a representative selection of shaft and guard combinations shall be teste
41、d. 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 appropriate, recognized method. See Annex B for an example. 4.1.3 During testing,
42、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 a PTO drive-shaft of between 900 mm and 1 010 mm closed length for which it is
43、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. 4.2.2 All tests shall be carried out in accordance with the schedule and in the
44、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 mounted as specified for operational use and only fixed by their designated restrain
45、ing 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 even test environment is maintained, e.g. heat and the dust specified in 5.2.3.
46、 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 parameters 5.2.1 Measuring accuracy All measurements shall be within the tolerances giv

The sodium chloride shall be white and
49、 shall give a colourless solution in water. It shall be substantially free from copper and nickel, and shall not contain more than 0,1 % of sodium iodine and not more than 0,4 % of total impurities calculated for dry salt. 5.2.3 Test dust 5.2.3.1 The test dust shall consist of a mixture composed of equal parts, by mass, of organic and mineral dust. 5.2.3.2 The organic dust shall be ground lucerne with a maximum percentage of 12 % water and with a maximum particle size of 2 mm.
