Standards Development
This standard contains safety-related requirements for high pressure water jet units 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 units, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. All references to high pressure water jet units within this document include 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 units, 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 IEC 60335-2-79 (35 MPa is currently the upper limit for machines covered by EN IEC 60335-2-79.
The project will introduce the European modifications to EN IEC 63458-1
