【Test Element】
Used in the specified test environment as the ratio of the simulated concentration leaked from other parts of the mask into the mask to the simulated concentration outside the test environment.
【Applicable standard】
EN136 EN149ISO13982
JG455-II Respirator Leak Testing System (European Standard)
【Product Description】
1. The environmental test chamber has dimensions of 2000Wx2000Dx2500H m and a volume of 10 m3. The cabin is made of stainless steel frame and tempered glass.
2. The constant flow network at the top of the test chamber causes the gas to form an uneven vortex, accelerates the mixing of gases, so that there is no dead space in the chamber, and uniformity of contaminants is required. experiment can be achieved after several cycles.
3. The overall structure of the environmental test chamber is mainly composed of the cabin body, air purification system, exhaust duct and air sampling system
4. The test gas enters the enclosure through a flow distributor from above and directed downwards at the subject's head with a minimum flow rate of 0.12 m/s. The concentration of the test agent in the effective working volume followst check for uniformity. The flow rate should be measured close to the subject's head.
5. Built-in horizontal treadmill that can run at 6km/h
【Technical Parameters】
1. Test chamber volume: 10 m3
2. Dimensions inside the test chamber: 2000 x 2000 x 2500 mm (LxWxH), tolerance +0.5 m33. Material: tempered glassGlass
