AS/NZS 4233.2:2013
High pressure water jetting systems - Part 2: Construction and performance
Sets out requirements for the design, construction testing, inspection and safeguarding of high pressure water jetting systems. 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 of 5600 bar litres per minute (identified as Class B). Safe operation and maintenance of high pressure water jetting systems is not covered by this Standard but is given in AS/NZS 4233.1.
