Highlights \/ Outstanding Features \/ Characteristics<\/h2>\n
    \n
  1. Digital Data Acquisition: Utilizes a computer, PLC, and acquisition modules for data processing, enabling real-time monitoring.<\/li>\n
  2. Precise Calibration: Equipped with a T-type calibration burner, a wet test meter (accuracy 0.2 L\/min), and multi-flow (1\/4\/6\/8 L\/min) calibration gas lines to ensure the legal validity and traceability of every test result.<\/li>\n
  3. High-Efficiency Insulation: The apparatus is insulated with 25mm thick, low-density, high-temperature resistant glass fiber.<\/li>\n
  4. Thermopile Heat Flux Measurement: Employs a thermopile (rather than a single-point thermocouple) to measure heat flux, which more accurately reflects the overall heat flux and minimizes errors caused by local fluctuations.<\/li>\n<\/ol>\n

    Test Methods \/ Procedures<\/h2>\n
      \n
    • A test sample is placed into a chamber with a constant flow of air.<\/li>\n
    • A radiant heat source is applied to the exposed surface of the sample.<\/li>\n
    • The changes in temperature of the gas are monitored and recorded.<\/li>\n
    • The pass\/fail criterion is based on the heat release rate calculated from this data.<\/li>\n<\/ul>\n

      Specifications<\/h2>\n
        \n
      1. Heat Release Rate Apparatus (insulated with 25mm thick, low-density, high-temperature resistant glass fiber)<\/li>\n
      2. The thermopile consists of five chromel-alumel thermocouples connected in series with five cold junctions and five hot junctions.<\/li>\n
      3. Equipped with a thermopile-type heat flux meter and a portable water cooling system.<\/li>\n
      4. Radiant heat source consisting of four silicon carbide elements, LL type, (508\u00d716)mm, with a nominal resistance of 1.4\u03a9, capable of generating heat flux densities up to 10W\/cm\u00b2.<\/li>\n
      5. The burner assembly comprises an upper burner and a lower burner, positioned at the top and bottom of the specimen, respectively.<\/li>\n
      6. Air distribution system: Air enters the test chamber after being distributed by two perforated plates.<\/li>\n
      7. Exhaust duct: Installed at the outlet of the cone.<\/li>\n
      8. The specimen\u00a0holder\u00a0consists\u00a0of\u00a0a\u00a0holder\u00a0body\u00a0and\u00a0a\u00a0drip\u00a0tray.<\/li>\n<\/ol>\n
