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

9、of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be

15、0474-10:2017(E) Introduction This document is a type-C standard as stated in ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the Scope of this document. When requirements of this type-C standard are different f

16、rom those which are stated in type-A or B standards, the requirements of this type-C standard take precedence over the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C standard. ISO 20474 provides acceptable safety requir

17、ements for earth-moving machinery. This standard does not necessarily provide requirements to meet all national and regional regulatory provisions, e.g. Japan does not allow object handling with earth-moving machinery. ISO 2017 All rights reserved v Earth-moving machinery Safety Part 10: Requirement

18、s for trenchers 1 Scope This document gives the safety requirements specific to trenchers as defined in ISO 6165. It is intended to be used in conjunction with ISO 20474-1, which specifies general safety requirements common to two or more earth-moving machine families. The specific requirements give

19、n in this document take precedence over the general requirements of ISO 20474-1. This document deals with all significant hazards, hazardous situations and events relevant to the earth- moving machinery within its scope (see ISO 20474-1:2017, Annex A) when used as intended or under conditions of mis

20、use reasonably foreseeable by the manufacturer. It specifies the appropriate technical measures for eliminating or reducing risks arising from relevant hazards, hazardous situations or events during commissioning, operation and maintenance.
