We would refer to VDI-2035 Sheet1&2, DIN EN 14336 and DIN EN 14868 with regard to the properties
of the medium used to protect the equipment. The following values provide further guidance.
The water used should also be free of suspended matter, dust etc. and any additional substances that
could cause reactions.
