DIN EN ISO 4254-7:2011-05

This Type-C standard contains safety requirements. It contains the German version of ISO 4254-7:2008 which has been prepared by Technical Committee ISO/TC 23 "Tractors and machinery for agriculture and forestry", Subcommittee 7 "Equipment for harvesting and conservation" of the International Organization for Standardization and which has been adopted as EN ISO 4254-7:2009 by Technical Committee CEN/TC 144 "Tractors and machinery for agriculture and forestry" (secretariat: AFNOR, France) of the European Committee for Standardization (CEN). The national interests during the preparation of this standard were represented by Working Committee NA 060-16-04 "Harvesting equipment", Technical Section "Agricultural engineering" of the Mechanical Engineering Standards Committee (NAM) at DIN. This standard defines relevant requirements set out in Annex I of the new EC Machinery Directive 2006/42/EC, relating to combine harvesters, forage harvesters and cotton harvesters which were placed on the EEA market for the first time, with the intent of simplifying the means of proving conformity with such requirements. Once this standard is designated a harmonized standard in the Official Journal of the European Communities, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (the so-called presumption of conformity). This part of ISO 4254, intended to be used together with ISO 4254-1, contains the safety requirements and their verification for the design and construction of combine harvesters, forage harvesters and cotton harvesters. It describes measures for the elimination or reduction of hazards arising from the intended use 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 provided by the manufacturer. When provisions of this part of ISO 4254 are different from those which are specified in ISO 4254-1, the provisions of this part of ISO 4254 take precedence over the provisions of ISO 4254-1 for machines that have been designed and built according 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 (as listed in Table 1), hazardous situations and events relevant to combine harvesters, forage harvesters and cotton harvesters, when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4). It is not applicable to hazards arising from the presence of persons other than the operator, cleaning of the grain tank, and hazards related to vibrations and moving parts for power transmission, except for strength requirements for guards and barriers. In respect of braking and steering, it is applicable only to the ergonomic aspects (for example, location of brake pedal and steering wheel); no other aspects related to braking and steering are covered. In the case of trailed harvesters, it is applicable only to hazards related to the working process.
