A. Overview
Theface mask leaking rate test system is designed according to the relevantstandard of "GB 2626-2019: Respiratory protection—Non-poweredair-purifying particle respirator", which is used to meet the leaking testof daily face masks and anti-particulate masks.
B. Applicable Standards:
GB/T32610-2016: Technical specification of daily protective mask
GB2626-2019: Respiratory protection—Non-powered air-purifying particle respirator
C. Components:
1. Aerosolgenerator: Nacl (KCl) aerosol generator, DEHS aerosol generator.
2. Photometer:mainly used to monitor the concentration of particles inside and outside themask and the concentration of particles inside and outside the cabinet.
3. Importedair pump: mainly used for the test flow through the filter material, the flowis stable and environmentally friendly. The vibration noise is low.
4. Electricalcontrol and software: circuit control and operation of the equipment, softwarecalculation and data processing, stability determination of upstreamconcentration, operation control, parameter setting
D. Accessories:
1. 1Aerosol generator
2. 1Set of standard mask fixtures
3. 1test cabin
