What is BS EN 3844‑3-Flammability of non-metallic materials in aerospace applications about?
BS EN 3844‑3 is part third of a multi-series standard that covers technical specifications for the determination of resistance of material to flame and glow propagation and to flame penetration which facilitates planning and designing of interior structure of aircrafts that complies with required regulations.
BS EN 3844‑3 specifies the test for the determination of the resistance of non-metallic materials in part or in whole to flame and glow propagation and to flame penetration.
BS EN 3844‑3 test method is also used for testing non-metallic materials which have to meet the test criteria for the 45° Bunsen burner test.
BS EN 3844‑3 is used for evaluation of non-metallic materials or constructions used in the interiors of aerospace vehicles but also may be used in other applications as specified in applicable procurement and regulatory documents.
Note: BS EN 3844‑3 is not used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions.
Who is BS EN 3844‑3-Flammability of non-metallic materials in aerospace applications for?
BS EN 3844‑3 on flammability of non-metallic materials in aerospace applications applies to:
- Manufacturers of non-metallic aircraft components
- Dealers and importers of non-metallic aircraft components
- Testing houses and labs for aircraft industry
- Safety and inspection services
- Disaster management personnel
Why should you use BS EN 3844‑3-Flammability of non-metallic materials in aerospace applications?
Non-metallic materials provide higher strength to weight ratio, design flexibility, easy repairability than metallic counterparts. Plastic and reinforced plastics are prime examples of non-metallic aeroplane components. Plastics are utilized in a variety of ways in modern aeroplanes and are susceptible to fire.
BS EN 3844‑3 provides you with a testing method to measure and describe the properties of non-metallic materials, products or assemblies in response to heat and flame under controlled laboratory conditions which allow you to determine the flammability of non-metallic materials in aerospace applications and effectively design interiors of aerospace vehicles.
BS EN 3844‑3 provides you guidance on principle, designation, test apparatus, test specimens, conditioning, burner adjustment, test procedure and test report which ensures you do the method correctly and get accurate results.
Results obtained in BS EN 3844‑3 can be used as elements of a fire risk assessment that takes into account all the factors which are relevant to an assessment of the fire hazards.
What’s changed since the last update?
BS EN 3844‑3:2019 supersedes BS EN 3844‑3:2011, which is now withdrawn.
