ISO 4254-7:2017与ISO 4254-1一起使用时，规定了联合收割机、饲料收割机、棉花收割机和甘蔗收割机设计和建造的安全要求及其验证。它描述了在正常操作和服务过程中，一个人（操作员）预期使用这些机器时，消除或减少危险的方法。此外，它还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中的规定不同时，对于根据ISO 4254-7:2017的规定设计和制造的机器，ISO 4254-7:2017的规定优先于ISO 4254-1的规定。 ISO 4254-7:2017与ISO 4254-1一起处理了联合收割机、饲料收割机、棉花收割机和甘蔗收割机按预期使用时，以及在制造商可合理预见的误用条件下（见附录A）的所有重大危险（如表A.1所列）、危险情况和事件。 除防护装置和障碍物的强度要求外，它不适用于由操作员以外的人员在场、谷物箱清洁、与振动和动力传输运动部件相关的危险。在制动和转向方面，仅适用于人体工程学方面（例如制动踏板和方向盘的位置）；没有涉及与制动和转向相关的其他方面。对于牵引式收割机，它仅适用于与工作过程有关的危险。 ISO 4254-7:2017未规定防滚翻保护结构（如适用）的设计要求。 ISO 4254-7:2017中未给出符合ISO 25119或ISO 13849的控制系统安全相关部件的性能水平（或类别）。 注:ISO 4254-7:2017未考虑与道路交通法规相关的具体要求。 ISO 4254-7:2017不适用于出版日期之前制造的机器。

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.
