Highlights \/ Outstanding Features \/ Characteristics<\/h2>\n
    \n
  1. Full-dimensional Environmental Simulation:\u00a0Features a 3.05m test chamber with precise wind control to replicate real-world flight conditions.<\/li>\n
  2. Dual-dimensional Thermal Monitoring:\u00a0Combines unexposed-side heat flux meters and a 7-point K-type thermocouple array for synchronous “heat flux + temperature” data, evaluating insulation and structural integrity.<\/li>\n
  3. Industrial-grade Structural Stability:\u00a0Uses a variable-thickness steel frame (6.4mm center \/ 3.2mm edge) to maximize strength, minimize deformation, and ensure specimen stability.<\/li>\n
  4. Aviation Fuel Compatibility:\u00a0Utilizes JP-8\/Jet A fuel to simulate authentic aviation fire scenarios, ensuring accurate, native-level safety validation.<\/li>\n<\/ol>\n

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

    Two thermal\/acoustic insulation blanket specimens are mounted at a 30\u00b0 inclination (forming a 60\u00b0 angle between the planes) and directly exposed to a high-intensity open flame for 4 minutes. The “burn-through time” is monitored in real-time;\u00a0failure is determined\u00a0if the specimen is physically penetrated by flames or if the heat flux on the unexposed side exceeds 2.27 W\/cm\u00b2.<\/p>\n

            Brief Introduction<\/h2>\n

            Applicable to the flame burn-through resistance testing of aircraft cabin thermal\/acoustic insulation materials. This test evaluates whether thermal\/acoustic insulation installed in the lower fuselage (typically on transport category airplanes with a seating capacity of 20 or more) possesses sufficient resistance to burn-through when subjected to sustained exposure from a standard high-intensity fire source.<\/p>","protected":false},"featured_media":622,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[18,156],"product_tag":[],"class_list":["post-621","product","type-product","status-publish","has-post-thumbnail","product_cat-all-product","product_cat-far-aviation","first","instock","shipping-taxable","product-type-simple"],"acf":[],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
