Hydrotest la dwe aplike yon presyon egal a 60% nan strenght a sede minimòm pou omwen 5 segonn nan kondisyon atmosferik. Presyon an maksimòm pa dwe plis pase 2500 psi pou tiyo jiska 3 pous, ak 2800 pou pi gwo gwosè. Si adisyonèl, ki pa estanda, tès yo egzekite, tiyo a va pote yon "S" make sou chak longè oswa tiyo pake.

The maximum pressure shall not exceed 2500 psi for pipes up to 3 inches, and 2800 for larger sizes. If additional, non standard, tests are executed, the pipe shall bear an "S" mark on each lenght or pipe bundle.
