Behind every safe and smooth flight is the full contribution of every aviation crew member. It is the production of strict quality standards for aircraft parts by every aviation product design and manufacturing unit, and every time it is stipulated in the aviation safety management mechanism and system. The standard operation performed under the following. Aviation safety is a matter of life, and there is no room for negligence.
When decorating the aircraft, flame-retardant or flame-retardant materials should be used, and combustible and flammable materials should be used as little as possible. On the basis of ensuring that the interior decoration of the aircraft is comfortable and beautiful, pay attention to meeting certain fire protection requirements. According to relevant military and aviation standards, aircraft manufacturers strictly control and select raw materials and accessories. Our experts have rich experience in the field of aircraft material fire safety, and will provide a series of professional fire protection solutions for aircraft material manufacturers, suppliers and operators, and solve problems for enterprises with their professional experience and services.
Due to the large number of passengers, the high risk of fire and the difficulty of escape, the required flame retardant performance level is also very strict.
Fire test of aircraft materials, fire test to prove that acceptable control of fire hazard is achieved
When the surface of all the main materials used is exposed to the fire source, the acceptable control of the total level of heat, smoke and poisonous gas is achieved. All the materials or articles used as fireproof boards are required to play a role when exposed to the fire source. The materials and articles should achieve acceptable fire performance
The full name of ATIM is Airbus Industries Test Methods, that is, Airbus Industries Test Methods ABD0031. The AITM standard outlines the fire safety design standard for the use of materials in the cabin of Airbus commercial aircraft. The fire-resistant design standard relates to the combustion performance of materials, components, parts and system components. Including the corresponding airworthiness and flight resistance authority certification requirements and Airbus “combustion-smoke-toxicity” fire resistance requirements.
The OSU heat release rate tester approved by FAA of the Federal Aviation Administration of the United States was originally designed by Smith of Ohio State University in 1972, and later became a FAA designated combustion test instrument for testing the heat release rate of Aeronautical materials. The test standards are FAR Part 25 Appendix F Part IV, Airbus AITM 2.00. 06, Boeing BSS 7322.
