scope:

This document contains the safety-related requirements made for the intended use and the conditions
foreseen by the manufacturer of high pressure cleaners and high pressure water jet machines with drives of all kinds (electric motor, internal combustion engine, air and hydraulic) in which pumps are used to generate pressure, together with any components and accessories. This document takes into account the significant hazards appearing during the use of the machines described.
All references to high pressure water jet machines within this document shall include the different
industrial applications listed. The word "spray" is used for spraying as well as for cutting procedures.
The high pressure water jet machines treated by this standard are intended 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 250 bar.
NOTE In general the machines in the scope will not be in the scope of the Pressure Equipment Directive 97/23/EC. In some cases specific parts may be in the scope of that directive, but its application is not dealt with in this document.
This document does not apply to high pressure cleaners which are dealt with in EN 60335-2-54 and
EN 60335-2-79.
This document deals with safety requirements to minimise the significant hazards listed in Clause 4 which can arise from assembling, erecting, operating and servicing of high pressure water jet machines.
This document does not cover additional hazards due to the incorporation of high pressure water jet
machines into other process-technology machines.
This document does not cover specific hazards associated with explosive atmospheres, use on ships or extreme ambient temperatures (less than 5°C or higher than 40°C).
This document does not cover hazards associated with the drives or specific hazards due to any heat
generation function. However the hazards due to high temperatures of touchable surfaces are dealt with.
Any hazard due to the nature of fluid other than that due to pressure is excluded from the scope of this standard.
This document applies to high pressure water jet machines that were manufactured/introduced to the
market after the date of publication of this standard.
NOTE For machines of similar application that are outside of the scope of this document and for which there is no alternative document available the relevant clauses of this document may be used.
