Goggle dust protection performance test device for eye protection after chemical mist droplet test protection performance test. Before the dust test, the reflectivity of the white paper is tested. Then put the head mould of the mounted specimen into the dust generating cabinet, close the glass cover tightly, turn on the air compressor, keep it for 1min until all the dust settles and carefully remove
Equipment Application
The goggle dust protection performance test device is used to test the protective performance of eye protection after chemical mist drop testing. Before the dust test, the reflectivity of the white paper is tested. Then put the head mould of the mounted specimen into the dust cabinet, close the glass cover, start the air compressor and keep it for 1min until all the dust settles, carefully take out the white paper and test its reflectivity, then, calculate its reflectivity ratio before and after the dust test, the reflectivity ratio after the test and before the test is more than 80%.
Conformity to standards.
This test device applies to the standard:
-2006 Technical Requirements for Eye Protectors for Personal Use, chapters 5.14 and 6.9.
Goggles dust protection performance test device main technical parameters: 1.
1, dust generating cabinet size: internal 560mm x 560mm x 560mm, sealed funnel type bottom.
2, air compressor: air volume of about 2.8m³/min, pressure of 2255.5Pa, air compressor airflow into vortex.
3, test dust: 100g of coal dust, particle size: 250µm (passage rate greater than: 95%), 125µm (passage rate greater than: 85%), 90µm (passage rate greater than: 40%).
4. C84-III photoelectric reflectometer.
4.1, measuring range: 0-100.
4.2, Repeatability: 0.3.
4.3, display data proportional to the intensity of the reflected light.
4.4, the light puissance sensitivity of the instrument is approximately equal to the product of Sc and Y.
5, test head mould: standard national standard head mould, silicone material.
6,Covering fleece: surface quality 185g/m2
