AS 4233.1:2013

This Standard provides requirements and guidance for the operation and maintenance of water jetting equipment. It describes methods for eliminating hazards or minimizing risks associated with high pressure water jetting. This Standard applies to high pressure water jetting systems with an output capability greater than 800 bar litres per minute and less than 5600 bar litres per minute (identified as Class A) and systems with an output capability in excess 5600 bar litres per minute (identified as Class B).

This Standard applies to high pressure water jetting systems with an output capability greater than 800 bar litres per minute and less than 5600 bar litres per minute (identified as Class A) and systems with an output capability in excess 5600 bar litres per minute (identified as Class B).
This Standard applies to:
(a)High pressure water jetting systems pressurized by positive displacement pumps with an output capability greater than 800 bar litres per minute.
(b)High pressure water jetting operations carried out at pressures above 800 bar litres per minute and includes jetting operations involving the use of additives and abrasives.
(c)Water jetting operations below 800 bar litres per minute where there is a foreseeable risk of injury to operators.
NOTE: The guidance provided in this Standard may also be used for any water jetting operation.
