The Salt Mist test bench is designed to test PPE in order to determine the inward leakage coefficient and the penetration coefficient using a sodium chloride aerosol as a test substance.
DESCRIPTION
AUTOMATION
Automatic NaCl concentration control thanks to a unique salt generator of in-house development.
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 NaCl concentration with a laser photometer
Concentration* of sodium chloride in the air inside the test chamber from 4 to 12 mg/m3
NaCl particle size distribution range from 0,02 μm to 2,00 μm
Mass median diameter of NaCl particles 0.6 μm
* Deviation in volume of NaCl concentration not exceeding 10%
