The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indic

23、ated in the scope of this European Standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built a

24、ccording to the provisions of this type C standard. Where for clarity an example of a preventative measure is given in the text, this should not be considered as the only possible solution. Other solutions can be used as far as they fulfil correctly the criteria expressed in the requirement. This Eu

25、ropean Standard assumes, that the equipment is operated and maintained by trained personnel.“ 1 Scope This standard specifies requirements to be met by the manufacturer of abrasive blasting equipment for the foreseeable significant hazards due to design, construction and installation, during commiss

26、ioning, operation, maintenance and decommissioning of the equipment which employ either centrifugal force or compressed air as a means of accelerating abrasive to achieve the desired result. Abrasive blasting equipment covers: centrifugal blasting machines; air blasting machines; loading, conveying

27、and unloading systems for the workpieces. See Annex A for more details. This standard covers all foreseeable significant hazards which could be encountered during the lifetime of the machine as listed in clause 5. This standard does not apply to: mobile centrifugal blasting equipment; mobile air bla

28、sting equipment; wet blasting equipment; the general works compressed air supply system.
