    High Precision JB / T 10707 Smoke Emission Test , NES713 Smoke Density Test Apparatus

    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:


    ModelYY435
    Size1,185(W)×700(D)×2,100(H) mm
    PowerAC 220V, 50/60Hz, 10A
    WeightAbout 150kg
    InstructionsSupplied
    Exhaust50L/s
    ToolCompressed air, vacuum cleaners, methane, propane gas (optional)

    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)


    Toxicity Constitution& Concentration ( ppm )

    Carbon dioxide(CO2) 100,000

    Carbon monoxide(CO) 4,000

    Hydrogen sulphide(H2S) 750

    Ammonia(NH3) 750

    Formaldehyde(HCHO) 500

    Hydrogen chloride(HCl) 500

    Acrylonitrile(CH2CHCN) 400

    Sulphur dioxide(SO2) 400

    Nitrogen oxides(NO+NO2) 250

    Phenol(C6H5OH) 250

    Hydrogen cyanide(HCN) 150

    Hydrogen bromide(HBr) 150

    Hydrogen fluoride(HF) 100

    Phosgene(COCl2) 25
