9、will assist in the preparation of the consequent British Standard. If no comments are received to the contrary, then the UK will approve this draft and implement it as a British Standard. Comment is particularly welcome on national, legislative or similar deviations that may be necessary. Even if th
10、is draft standard is not approved by the UK, if it receives the necessary support in Europe, the UK will be obliged to publish the official English Language text unchanged as a British Standard and to withdraw any conflicting standard. UK Vote Please indicate whether you consider the UK should submi
11、t a negative (with reasons) or positive vote on this draft. Submission The guidance given below is intended to ensure that all comments receive efficient and appropriate attention by the responsible BSI committee.

36、57 GMT+00:00 2008, Uncontrolled Copy, (c) BSI ISO/DIS 4254-12 iv ISO 2007 All rights reserved Foreword 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 carrie
37、d 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. IS
38、O 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 main task of technical committees is to prepare Internatio
39、nal 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. Attention is drawn to the possibility that some of the ele
40、ments of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 4254-12 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 7, Equipment for harvesting and
41、 conservation. ISO 4254 consists of the following parts, under the general title Agricultural machinery Safety: Part 1: General requirements Part 2: Anhydrous ammonia applicators Part 3: Tractors Part 5: Power-driven soil-working equipment Part 6: Sprayers and liquid fertilizer distributors Part 7:
42、Combine harvesters, forage and cotton harvesters Part 9: Equipment for sowing, planting and distributing fertilizers Part 10: Rotary tedders and rakes Part 11: Pick-up balers Part 12: Rotary disc and drum mowers and flail-mowers Part 3, Tractors, is to be revised under a separate number and publishe
43、d as ISO 26322. Part 4, Forestry winches, is published as ISO 19472, Machinery for forestry Winches Terms and definitions, performance and safety.

44、 ISO 2007 All rights reserved v Introduction The structure of safety standards in the field of machinery is as follows: type-A standards (basis safety standards) giving basic concepts, principle for design, and general aspects that can be applied to machinery; type-B standards (generic safety standa
45、rds) dealing with one safety aspect or one type of safeguards that can be used across a wide range of machinery: type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise); type-B2 standards on safeguards (e.g. two-hands controls, interlocking devices, pressur
46、e sensitive devices, guards); type-C standards (machinery safety standards) dealing with detailed safety requirements for a particular machine or group of machines. This Standard is a type C standard as stated in ISO 12100-1. When provisions of this type C standard are different from those which are
47、 stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. The machinery concerned and the extent to which hazards, hazardous
48、situations and events are covered are indicated in the scope of this document.
