<\/p>\n

The FCZ-50 Textile Vertical Flammability Tester<\/strong> is a professional laboratory testing system designed to evaluate the flame resistance, afterflame time, afterglow time, and damaged length (char length) of vertically oriented textiles and protective fabrics. Built in compliance with ASTM D6413<\/strong>, 16 CFR Part 1615\/1616<\/strong>, ISO 6940\/6941<\/strong>, BS EN ISO 15025<\/strong>, and national standard GB\/T 5455-2014<\/strong>, this apparatus provides standardized test conditions for flame-retardant fabric qualification.<\/p>\n

Featuring a precision 11 mm inner-diameter Bunsen burner, dual specimen conditioning modes (3 s ignition for oven-dried samples and 12 s ignition for standard conditioned samples), a full range of standardized char length tear weights (54.5 g to 453.6 g), and high-resolution timing (0.1 s accuracy), this advanced Textile Vertical Burning Tester<\/strong> is an essential tool for garment manufacturers, technical textile mills, aerospace interior suppliers, and third-party testing laboratories.<\/p>\n

    System Architecture & Testing Workflow of FCZ-50 Textile Flammability Tester<\/h3>\n

    Standardized Testing Workflow:<\/strong><\/p>\n

      \n
    1. Cut specimens to 300 mm \u00d7 89 mm and condition according to Condition A (standard atmosphere) or Condition B (oven-dried at 105\u00b0C).<\/li>\n
    2. Mount the sample inside the 356 mm \u00d7 51 mm vertical specimen holder and suspend it in the combustion chamber.<\/li>\n
    3. Select test gas (propane\/butane for Condition A or Methane \u226597% for Condition B) and set ignition timer (12 s or 3 s).<\/li>\n
    4. Apply flame exposure. Automatically record afterflame time (duration sample continues burning after burner shuts off) and afterglow time.<\/li>\n
    5. Attach the designated weight (based on fabric mass per unit area from Table 2) to the bottom corner of the burned sample, lift slowly, and measure the resulting damaged length (char length).<\/li>\n<\/ol>\n

      Target Customer Applications:<\/strong><\/p>\n

        FCZ-50 Textile Vertical Flammability Tester FAQ<\/h3>\n

        Q1: What parameters are measured during a vertical fabric flammability test?<\/h4>\n

        A:<\/strong> The FCZ-50 evaluates three critical parameters: Afterflame Time (duration of visible flame after burner removal), Afterglow Time (duration of flameless glowing combustion), and Damaged Length (char length measured using standardized tear weights).<\/p>\n

        Q2: How is the char length weight chosen for testing?<\/h4>\n

        A:<\/strong> The tear weight is determined by fabric mass per unit area (g\/m\u00b2):<\/p>\n

          \n
        • \u2264 101 g\/m\u00b2: 54.5 g weight<\/li>\n
        • > 101 to \u2264 207 g\/m\u00b2: 113.4 g weight<\/li>\n
        • > 207 to \u2264 338 g\/m\u00b2: 226.8 g weight<\/li>\n
        • > 338 to < 650 g\/m\u00b2: 340.2 g weight<\/li>\n
        • \u2265 650 g\/m\u00b2: 453.6 g weight<\/li>\n<\/ul>\n

          Q3: Can this device be used for ASTM D6413 workwear testing?<\/h4>\n

          A:<\/strong> Yes. The vertical specimen frame, 11 mm Bunsen burner nozzle, 12 s ignition timer, and specified char length weights align with ASTM D6413 requirements.<\/p>","protected":false},"excerpt":{"rendered":"
