当与ISO 4254-1一起使用时，ISO 4254-7:2017规定了联合收割机，饲料收割机，棉花收割机和甘蔗收割机的设计和建造的安全要求和验证。它描述了一个人（操作员）在正常操作和服务过程中消除或减少这些机器打算使用的危险的方法。另外，它规定了制造商提供的安全工作实践信息的类型。 当ISO 4254-7:2017的规定与ISO 4254-1中规定的规定不同时，ISO 4254-7:2017的规定优先于ISO 4254-1规定的设计和制造机器符合ISO 4254-7:2017的规定。 ISO 4254-7:2017与ISO 4254-1一起处理所有重大危险（如表A.1所列），与联合收割机，饲料收割机，棉花收割机和甘蔗收割机相关的危险情况和事件，当它们按照预期和在制造商可合理预见的误用条件下使用时（见附录A）。它不适用于由操作员以外的人员出现的危险，清洁粮食储罐的振动和运动部件的危害，除了防护装置和障碍物的强度要求外。在制动和转向方面，它只适用于人体工程学方面（例如刹车踏板和方向盘的位置）。没有涉及制动和转向的其他方面。在牵引式收割机的情况下，仅适用于与工作过程相关的危险。 翻转保护结构的设计要求（如适用）在ISO 4254-7:2017中没有规定。 根据ISO 25119或ISO 13849，控制系统安全相关部件的性能等级（或类别）未在ISO 4254-7:2017中给出。 注:ISO 4254-7:2017未考虑与道路交通法规有关的具体要求。 ISO 4254-7:2017不适用于在出版日期之前生产的机器。

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.
