1 Scope
This part of GB 25684 gives the safety requirements specific to roller.
It is intended to be used in conjunction with GB 25684.1, which specifies general safety requirements common to earth-moving machine families. The specific requirements given in this part take precedence over the general requirements of GB 25684.1.
This part is applicable to the roller as defined in GB/T 8498.
This part deals with all significant hazards, hazardous situations and events relevant to the earth-moving machinery within its Scope when used as intended or under conditions of misuse reasonably foreseeable by the manufacturer. It specifies the appropriate technical measures for eliminating or reducing risks arising from significant hazards, hazardous situations or events during application, operation and maintenance.
It is not applicable to machines manufactured before the date of its publication.
