    CSI-149A Protective Clothing Flammability Tester I, the use and implementation of standard protective clothing flammability tester, used to determine the tendency
    of textile re-ignition, shading and carbonization.

    It is suitable for the determination
    of flame retardant properties of woven fabrics, knitted fabrics, coated products, etc.

    Implement the standard GB19082-XXXX two, anti-working conditions and main technical indicators 1.
    Ambient temperature: -10 °C ~ 30 °C2.
    Relative humidity: ≤85%3.
    Supply voltage and power: 220V±10% 50HZ Power is less than 100W4.
    Color 7 inch touch screen display/control, Chinese and English switching 5.
    Touch screen resolution: 800*480;6, speed requirements (60±5)mm/s movement line speed through the flame; 7, The main controller adopts a low-power processor, automatically enters the energy-saving mode 8.
    The flame time applied by the Bunsen lamp is arbitrarily set, and the accuracy is ±0.
    1s
    .

    9, Bunsen lamp can be inclined in the range of 0-45 ° 10, Bunsen lamp high pressure automatic ignition, ignition time: arbitrarily set 11, gas source: according to the humidification conditions (see GB5455-2014 of 7.
    3) to select gas, condition A selection of industrial propane or butane or propane / butane mixed gas; Condition B is selected with a purity of not less than 97% methane
    .

    12, thermocouple probe measures flame temperature 0-1000 ° 13, flame ruler: flame height 40MM; 14, sample distance flame height requirements: factory calibrated, no customer adjustment, easy to use, easy to operate; 15, sample requirements: size is 105mmx50mm; 16, Dimensions: 950MM*550MM*550MM Three, number of flammable samples and requirements 1, at least from 3 pieces of protective clothing to cut samples, size is 105mmx50mm
    .

    Pre-treatment
    according to standard requirements.

    2, detection method 3, detection device
    .

    The height of the sample holder should be adjustable, can be moved horizontally or circumferentially, and the horizontal speed can be adjusted to any setting
    .

    After igniting the burner, adjust the flame so that the flame height at the top of the burner reaches (40±4)mm, and measure the flame temperature with a thermocouple probe with a diameter of about 1.
    5 mm above the top of the burner (20±2)mm, which should be (800±50) °C
    .

    During the test, the outside of the protective clothing material is facing the flame, so that the 105mm edge of the sample remains perpendicular to the direction of the sample movement, and the distance of the sample through the flame above the flame is 50mm
    .

    Pass through the flame at (60±5)mm/s linear velocity and record the combustion state
    of the sample after passing through a single flame.
