    Test Methods \/ Procedures<\/b><\/strong><\/h2>\n

    A specimen is positioned vertically in a standardized combustion chamber. It is exposed to a defined flame source from a wide-mouth sleeve gas burner (tilted at 45\u00b0) for a specific duration. The test monitors the material\u2019s reaction to fire, the spread of the flame, and the density of the smoke produced.<\/p>\n

    Key Procedure Steps:<\/h3>\n
      \n
    • Ignition: The burner is applied to the lower edge of the specimen for a duration of 3 minutes.<\/li>\n
    • Observation: After removing the flame, the operator records the after-flame time and after-glow time.<\/li>\n
    • Smoke Measurement: A specialized photometric system in the exhaust hood continuously measures the light attenuation (optical density) throughout the test.<\/li>\n
    • Dripping Behavior: The occurrence of any flaming or non-flaming droplets\/particles is noted.<\/li>\n<\/ul>\n

      Evaluation & Classification (per DIN 5510-2):<\/h3>\n

      Based on the test results, the material is categorized into three critical safety classes:<\/p>\n

        \n
      • Flammability (S-Class): Based on the Damaged Length and after-flame time.\n
          \n
        • Example: Class S4 (Damaged length \u2264 200 mm).<\/li>\n<\/ul>\n<\/li>\n
        • Smoke Development (SR-Class): Determined by the Integral of Light Attenuation (smoke integral).\n
            \n
          • Example: SR2 indicates low smoke production.<\/li>\n<\/ul>\n<\/li>\n
          • Dripping Behavior (ST-Class): Classified by whether the material forms flaming or non-flaming droplets.\n
              \n
            • Example: ST2 (No dripping observed).<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
