NBS Smoke Density Test Chamber ASTM E662 SUS 304 Stainless Steel
Description:
ISO 5659-2 Plastics Smoke Generation Optical Density Test Apparatus by Single Chamber Test is widely used in assessing characteristics of vehicle interior and inflammable cable. Measure the optical density of smoke when a certain thick specimen is exposed to a heat source of 50KW/m2.
Standards:
ISO 5659-2 Plastic smoke generation, determination of optical density by a single chamber test
GB/T 8323.2 Plastics -- Smoke generation -- Part 2: Determination of optical density by a single-chamber test
Specifications:
1. All the Inside & outer of the container are Teflon coated, can resist etchant gas to increase the life of machine;
2. The machine is all opened designed;
3. Install assistant heating device in the outer of the tester, it can set temperature according to different standard requirements, so can shorten the temperature balance time of container;
4. Install the aluminum explosion-proof in the container to avoid the life risk;
5. Open the gas pressure release on top of container, connect with the pressure adjust flask, can adjust the pressure automatically;
6. Install automatic air-cylinder in both top and bottom of container; it will be convenient for user;
7. Provide air-cooled copper calorimeter, can use back cooling mode to adjust it’s surface temperature when do the test;
8. Provide ISO 5659-2/GB/T8323 radiation cone devices, can provide 50kw/m2 heat radiation output;
9. Provide ISO 5659-2/GB/TB323 standard naked light burners can work with radiation cone to do naked light burning test;
10. Provide domestic water cool heat flow meter (cone calorimeter), provide the measurement certificate which can date back;
11. Provide self-circulating cooling water, it’ll be convenient for user;
12. Provide weighing device, can do MOD smoke density test and do heat weightless test;
13. The range of sensor is 0-5000g, the precision is 0.01g;
14. Provide NES 711 naked light burner and whisk fans
15. Adopted air joint connection between all-radiation furnace and radiation cone ,user just need to insert or pluck then can make the change ;
16. Install optical cassette on the top of container, side window photo multiplier for light source acceptance,s-4 rate respond transmission accuracy can reach 0.0001%;
17. Install wheel rotation device in the cassette, can automatically change CLEAR/FILTER/DARK according to smoke density transformation;
18. Install ND2 neutral filter in cassette, it will convenient for users self-adjust also can use for automatic change tab in test;
19. Under the container is filament lamp, can provide even light spot output;
20. Mains transformer from 220V to 110V.
