High Precision JB/T 10707 NES713 Smoke Toxicity Index Test Chamber
Description:
This tester measures the Toxicity Index by ppm in Naval Engineering
Standard chamber when complete combustion occurs by burner.
NES 713 TOXIC Chamber meets the standard of NES 713 and is used to
measure combustion characteristics about materials.
NES 713 Toxic Chamber measures Toxicity Index after perfect
combustion by burning 100g of specimen.
Standard:
NES 713: Determination Of the Toxicity Index Of the Products of
Combustion From Small Specimen of Materials
JB/T 10707: Low-Smoke Halogen-free Thermoplastic Compounds for
Flame Retardant Cables
Feature:
1. Observation window made in reinforced plastic allows easy
observation of combustion conditions during the test
2. Treating the inside of Chamber with Teflon Coating minimizes
chemical reaction with gaseous materials generated in combustion.
3. Door locking device designed for easy opening/closing.
4. Specimen Support for Burner to be located in the center of the
combustion mass and for test specimen to be easily loaded
5. Designed for testing in Auto/Manual Mode
6. Auto Ignition for controlling ignition and extinguishment of Gas
Burner by Time Device
7. Auto Vent Mode allowing auto release of combustion gases
generated in combustion by Time Device
8. Auto Stirrer Mode for complying with conditions of combustion
gas stirrer by Time Device specified in the standard Time Device
Specification:
| Model | YY435 |
| Size | 1,185(W)×700(D)×2,100(H) mm |
| Power | AC 220V, 50/60Hz, 10A |
| Weight | About 150kg |

Test Result:
If 100g of material is burned and the material is diluted in the
air of chamber, concentration of each generated gas is given by the
following equation.
C × 100 ×V
C8 = --------------- (ppm)
m
C = concentration of gas in test chamber (ppm)
m = fire test mass (g)
V = volume of test chamber (m3)
Toxicity Index
C81 C82 C83 C8n
Toxicity Index = Σ ------ + ------ + ------ + … + ------
Cf1 Cf2 Cf3 Cfn
1, 2, 3, ... indicates each found Gas.
Cf = concentration of the gas considered fatal to man for a 30
minute exposure time(ppm)
