1 Scope This European Standard contains safety-related requirements for high pressure water jet machines with drives of all kinds (e.g. electric motor, internal combustion engine, air and hydraulic) in which pumps are used to generate pressure. This document deals with all significant hazards, hazardous situations and events arising during assembly, erection, operation and servicing relevant to high pressure water jet machines , when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). All references to high pressure water jet machines within this document includes machines for one or more of the following industrial applications:
— cleaning;
— surface preparation;
— material removal;
— readjustment of concrete;
— cutting.
This document applies to mobile and fixed high pressure water jet machines , in which the water pressure is generated by a pressure generator /pump and in which the maximum allowable working pressure is more than the upper limit fixed in the scope of EN 60335�...
