Works testing
Every PAM pipe and fitting undergoes a works internal pressure test, in accordance with European and International Standards.
| Socket pipes | |
|---|---|
| DN | Works hydraulic test pressure DN (bar) |
| 60 to 300 | 40 |
| 350 to 600 | 30 |
| 700 to 1000 | 32 |
| 1100 to 2000 | 25 |
Class C
Every pipe is subjected to a works hydraulic pressure test at the pressure indicated in the table above.
Standards EN 545 and ISO 2531.
