BS EN 3844-1:2019

What is BS EN 3844‑1-Flammability of non-metallic materials in aerospace applications about? 

BS EN 3844‑1 is the first part of a multi-series standard that serves technical specifications for the determination of vertical flame propagation that enables planning and designing of the interior structure of aircraft that complies with required regulations. 

BS EN 3844‑1 specifies the test method for the determination of the vertical flame propagation and after flame time of non-metallic materials in part or in whole. 

BS EN 3844‑1 test method is also used for testing non-metallic materials which have to meet the test criteria for the vertical Bunsen burner test: 

• With a flame application time of 60 s 
• With a flame application time of 12 s 

BS EN 3844‑1 is used for the 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 3844‑1 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 3844‑1-Flammability of non-metallic materials in aerospace applications for? 

BS EN 3844‑1 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 3844‑1-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 airplane components. Plastics are utilized in a variety of ways in modern airplanes and are susceptible to fire. 

BS EN 3844‑1 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 allows you to determine the flammability of non-metallic materials in aerospace applications and effectively design interiors of aerospace vehicles. 

BS EN 3844‑1 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 3844‑1 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 3844‑1:2019 supersedes BS EN 3844‑1:2011, which is now withdrawn.
