Witryna29 lip 2024 · The leakage rate was calculated from the pressure difference measured in these two hours. As metallic seals were used to seal the pipe transitions of the set-up, the measured leakage rate is assumed to be only due to leakage at the O-ring. All static measurements were performed at 20 °C, 60 °C, and −30 °C (HNBR) or −40 °C (EPDM). WitrynaIf the rate of rise is less than 1 x 10-5 Torr.liters/second, the system is in excellent shape, clean and leak free. 1 – 3 x 10-5 Torr.liters/sec = Good, clean leak free 4 – 6 x 10-5 Torr.liters/sec = Probably dirty, maybe a small leak 7 – 9 x 10-5 Torr.liters/sec = Probably dirty and leaking 1 x 10-4 Torr.liters/sec = Dirty and leaking
