NF EN ISO 4254-7
Agriculural machinery - safety - Part 7 : combine harvesters, forage harvesters and cotton harvesters
ISO 4254-7:2008, intended to be used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of combine harvesters, forage harvesters and cotton harvesters. It describes methods 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.Taken together with ISO 4254-1, ISO 4254-7:2008 deals with all the significant hazards, 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. 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 (e.g. 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.

Le présent document, préparé dans le but de donner des moyens de se conformer aux exigences de la Directive Machines (89/392/CEE modifiée par les Directives 91/368/CEE, 91/44/CEE et 93/68/CEE), détermine les prescriptions de sécurité et les vérifications pour la conception et la construction des moissonneuses-batteuses et récolteuses-hacheuses automotrices, tractées ou portées.
ISO 4254-7:2017, when used together with ISO 4254‑1, specifies the safety requirements and their verification for the design and construction of combine harvesters, forage harvesters, cotton harvesters and sugar cane harvesters. It describes methods 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 ISO 4254-7:2017 are different from those which are stated in ISO 4254‑1, the provisions of ISO 4254-7:2017 take precedence over the provisions of ISO 4254‑1 for machines that have been designed and built according to the provisions of ISO 4254-7:2017. ISO 4254-7:2017, taken together with ISO 4254‑1, deals with all the significant hazards (as listed in Table A.1), hazardous situations and events relevant to combine harvesters, forage harvesters, cotton harvesters and sugar cane harvesters, when they are used as intended and under the conditions of misuse that are reasonably foreseeable by the manufacturer (see Annex A). 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 (e.g. 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. Design requirements for roll-over protective structures (if applicable) are not specified in ISO 4254-7:2017. Performance levels (or categories) for safety-related parts of control systems in accordance with ISO 25119 or ISO 13849 are not given in ISO 4254-7:2017. NOTE Specific requirements related to road traffic regulations are not taken into account in ISO 4254-7:2017. ISO 4254-7:2017 is not applicable to machines manufactured before the date of its publication.
