13、ling clients of the SABS .ISO 20474-8:2008(E) ISO 2008 All rights reserved iiiForeword 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 IS
14、O 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 c
15、losely 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 main task of technical committees is to prepare International Standards. D
16、raft 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 do
17、cument may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 20474-8 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 2, Safety, ergonomics and general requirements. ISO 20474 consists of the f
18、ollowing parts, under the general title Earth-moving machinery Safety: Part 1: General requirements Part 2: Requirements for tractor-dozers Part 3: Requirements for loaders Part 4: Requirements for backhoe-loaders Part 5: Requirements for hydraulic excavators Part 6: Requirements for dumpers Part 7:

The mach
21、inery concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the Scope of this document. When requirements of this type-C standard are different from those which are stated in type-A or B standards, the requirements of this type-C standard ta
22、ke precedence over the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C standard. Provisions that are applicable for Australia, EU, Japan or the USA, and which are mandatory for compliance with specific governmental laws,
23、 directives or regulations in force in the particular country or region, are given in ISO/TS 20474-14. NOTE Other countries or regions may also have regional requirements.

24、NATIONAL STANDARD ISO 20474-8:2008(E) ISO 2008 All rights reserved 1Earth-moving machinery Safety Part 8: Requirements for graders 1 Scope This part of ISO 20474 gives the safety requirements specific to graders as defined in ISO 6165. It is intended to be used in conjunction with ISO 20474-1, which
25、 specifies general safety requirements common to earth-moving machine families, and with ISO/TS 20474-14, which gives information on provisions that are mandatory in particular countries or regions. The specific requirements given in this part of ISO 20474 take precedence over the general requiremen
26、ts of ISO 20474-1. This part of ISO 20474 deals with all significant hazards, hazardous situations and events relevant to the earth-moving machinery within its Scope when used as intended or under conditions of misuse reasonably foreseeable by the manufacturer (see also ISO/TS 20474-14). It specifie
27、s the appropriate technical measures for eliminating or reducing risks arising from significant hazards, hazardous situations or events during commissioning, operation and maintenance. It is not applicable to machines manufactured before the date of its publication. 2 Normative references The follow
28、ing referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
