How to mask leak detection
1. Detection positions: with large observation window sealable chamber, the size may allow subjects completed the prescribed action; should be designed so that the analog agent from the warehouse into the top of the uniform, and in the lower compartment is discharged from the exhaust port.
2. mimetic generating device shall comply with one of the following requirements:
3.1 NaCl particles: the occurrence of gas is not less than 100 L / min, the particle concentration of (102) mg / m3, the concentration changes in the available space within the test chamber should not exceed 10%; aerodynamic particle size distribution should be 0.02μm to 2μm, mass median diameter of about 0.6μm.
4. Oil particles: should be harmless to the human body, such as corn oil, paraffin oil; gas occurs not less than 100 L / min the particle concentration of (2030) mg / m3 concentration change in the available space within the test chamber should be high kinetics of particle size of particulate matter in the air distribution 10 should be 0.02μm to 2μm mass median diameter of about 0.3μm
