What is BS EN4551-4:2017

BS EN4551-4:2017 is a technical standard developed by the European Standards Committee for Aerospace Industries (CEN/TC 15) that focuses on evaluating the flammability resistance of materials used in aircraft interiors. This standard provides guidelines and test methods for assessing the fire performance of different materials, ensuring the safety and reliability of aircraft components.

Understanding the Scope

The scope of BS EN4551-4:2017 covers a wide range of materials used in aircraft interiors, including textiles, leathers, foams, and coatings. It sets out specific requirements and conditions for testing these materials' resistance to flame propagation, heat release, smoke production, and toxic gas emission. By adhering to this standard, manufacturers can ensure the materials they use meet the stringent safety regulations and minimize the risk of fires on board.

Testing Procedures and Requirements

The testing procedures and requirements outlined in BS EN4551-4:2017 are designed to replicate real-life scenarios and assess the materials' performance under different fire conditions. Some of the key tests include the horizontal flame test, heat release test, smoke density test, and toxicity test. These tests evaluate the materials' ability to resist ignition, limit the spread of flames, release minimal heat and smoke, and reduce the emission of toxic gases during combustion.

Benefits and Compliance

Complying with BS EN4551-4:2017 offers several benefits to aerospace manufacturers, operators, and passengers. By using materials certified under this standard, the risk of fire-related accidents can be greatly reduced. The standard also ensures uniformity in testing methods and requirements across the industry, making it easier for manufacturers to compare and select materials for their aircraft interiors. Moreover, compliance with this standard enhances the overall safety and quality of aircraft interiors, instilling confidence in passengers and ensuring a safer flying experience.
