StClingin im from New Zealand as well, we use three pressure lable things on pipes heres the first.
Class A=low pressure
Class B=medium pressure
Class C=80psi max
Class D=145psi max
Class E=170psi max
Class F=260psi max
Class 1-18
1 being the lowest pressure
18 being the highest
1=1BAR(7psi)
2=2BAR
etc
18=18BAR(260psi)
now if it doesnt have those on the pipe it might have PN which stands for "Pressure Number" if it has PN12 that means 12BAR(173psi)
i think thats all correct i may be a tad off
