This document 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 Annex ZA). 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.
NOTE 1 List of significant hazards is given in informative Annex D.
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 60335-2-79:2012.
NOTE 2 35 MPa is currently the upper limit for machines covered by EN 60335-2-79:2012.
This document does not cover:
- requirements of the Pressure Equipment Directive 2014/68/EU;
NOTE 3 In some cases, specific parts can be in the scope of that directive, but their application is not dealt with in this document.
- high pressure cleaners which are dealt with in EN 60335-2-54:2008, EN 60335-2-54:2008/A11:2012, EN 60335-2-54:2008/A11:2012/AC:2015, EN 60335-2-54:2008/A1:2015 and EN 60335-2-79:2012;
NOTE 4 EN 60335-2-54:2008, EN 60335-2-54:2008/A11:2012, EN 60335-2-54:2008/A11:2012/AC:2015 and EN 60335-2-54:2008A1:2015 applies to steam cleaners for household use. EN 60335-2-79:2012 applies to high pressure cleaners having a rated pressure not less than 2,5 MPa and not exceeding 35 MPa, as well as steam cleaners and those parts of hot water high pressure clea ...
