The Elegaz test bench is designed to test PPE in order to determine the inward leakage coefficient and the penetration coefficient using a sulphur hexafluoride (SF6) as a test substance.
Automatic SF6 concentration control.
Automatic air flow control in the chamber, adjustment of wind speed and direction, using built-in fan systems.
Communication with the test operator through a system of speakers built into the treadmill.
Recording of all required test parameters in the database for their subsequent analysis Automatic
Linear airflow speed through the chamber, close to the test operator’s head when he is standing in the middle of the treadmill with the additional fans switched off from 0,12 to 0,2 m/s
Additional air flow speed (if necessary) near the test operator’s head 2 m/s
Horizontal treadmill tape speed from 0 to 6 km/h
Air flow rate provided by the sampling pump from 0,3 to 3,0 dm3/min
Continuous measurement of SF6 concentration with FT-IR spectrometer
Spread of SF6 concentration in the chamber not more than 10%
Concentration of sulphur hexafluoride in the air inside the test chamber from 0,1% to 1,0%.
Response time of the entire detection system to obtain a measurement result corresponding to 10% – 90% over the entire measurement range not more than 20 s
