48、azards, 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 requirements of the
49、 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 regulatory provisions, e.g. Japan does not allow object handling with earth-moving machinery.
