32、t 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 from those which are stated in type-A or B standards, the requirements of this type-C standard take precedence over the require

33、ments 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 requirements for earth-moving machinery. This standard does not necessarily provide requirements to meet all national and regional re

The specific requirements given in this document take precedence over the general requirements of ISO 2

36、0474-1.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 misuse reasonably foreseeable by the manufacturer. It specifies the appropriat
