Q. What is a Class B Water Jetter? A. Any machine over 5600 'bar litres'
Q. Is my Jetter Class B? A. Complete this simple calculation:
5000psi Jetter at 22lpm. Convert to bar pressure first.
5000psi divided by 14.5 = 345 bar.
345 bar x 22lpm = 7,950 bar.
This is above 5600 bar litres making it a Class B machine.
Any pump under 5,600 bar litres is considered Class A.
The Australian Standards for High Pressure Water Jetting (AS/NZS 4233.1:2013 7.3.3) states that "All operators shall be appropriately trained and assessed as competent/capable. Training shall be delivered through an RTO and be in accordance with the high pressure water jetting Units of Competency. Trainers shall be accredited by an RTO and shall have relevant water jetting experience."
