14、13:2012(E)ForewordISO (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
15、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 closely with the International Electrotechnical Commission (IEC) on al
16、l matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. Th

28、13:2012(E)IntroductionThe 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 standards) dealing with one s
29、afety 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-hand control devices, interlocking devices, pressure-sensitive devic
30、es, guards); type-C standards (machinery safety standards) dealing with detailed safety requirements for a particular machine or group of machines.This document is a type-C standard as stated in ISO 12100:2010.When provisions of this type-C standard are different from those which are stated in type-
31、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 situations and e
32、vents are covered are indicated in the scope of this part of ISO 4254. These hazards are specific to large rotary mowers.Significant hazards that are common to all agricultural machines (self-propelled ride-on, mounted, semi-mounted and trailed) are dealt with in ISO 4254-1.vi ISO 2012 All rights re
33、servedBS ISO 4254-13:2012Agricultural machinery Safety Part 13: Large rotary mowers1 ScopeThis part of ISO 4254, when used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of towed, semi-mounted, or mounted large rotary mowers with si
34、ngle or multiple cutting elements which have a cutting diameter of 1 000 mm or greater for any single cutting element assembly, mounted on a propelling tractor or machine, intended for agricultural mowing equipment and designed for shredding crop residue, grass and small brush by impact. It describe
35、s methods for the elimination or reduction of hazards arising from the intended use and reasonable foreseeable misuse of these machines by one person (the operator) in the course of normal operation and service. In addition, it specifies the type of information on safe working practices to be provid
36、ed by the manufacturer.NOTE 1 These machines can be used for shredding grass. When used outside agriculture, additional requirements not specified in this part of ISO 4254 can be applicable.This part of ISO 4254 is not applicable to: rotary disc mowers, rotary drum mowers, and flail mowers designed
37、for forage crop harvesting as covered by ISO 4254-12; arm-type large rotary mowers. pedestrian-controlled motor mowers; lawn mowers covered by ISO 5395.When requirements of this part of ISO 4254 are different from those which are stated in ISO 4254-1, the requirements of this part of ISO 4254 take p
38、recedence over the provisions of ISO 4254-1 for machines that have been designed and built according to the provisions of this part of ISO 4254.This part of ISO 4254, taken together with ISO 4254-1, deals with all the significant hazards, hazardous situations and events relevant to large rotary mowe
39、rs used as intended and under the conditions foreseen by the manufacturer. (A list of significant hazards is provided in Annex A.)NOTE 2 Example illustrations of two mowers (a rigid-deck large rotary mower and a trail-type multi-section foldable-wing large rotary mower) dealt with in this part of IS
40、O 4254 are shown in C.1.NOTE 3 Example illustrations of mowers not dealt with in this part of ISO 4254 are shown in C.2.This part of ISO 4254 is not applicable to environmental hazards, road safety, electromagnetic compatibility, vibration and hazards related to moving parts for power transmission.
41、It is also not applicable to hazards related to maintenance or repairs to be carried out by professional service personnel.NOTE 4 ISO 14982 specifies test methods and acceptance criteria for evaluating the electromagnetic compatibility of all kinds of mobile agricultural machinery.This part of ISO 4
42、254 is not applicable to large rotary mowers which are manufactured before the date of publication of this document by ISO.INTERNATIONAL STANDARD ISO 4254-13:2012(E) ISO 2012 All rights reserved 1BS ISO 4254-13:2012ISO 4254-13:2012(E)2 Normative referencesThe following documents, in whole or in part
