What is BS EN4559:2017?

BS EN4559:2017 is a technical specification that sets forth the requirements for flammability performance of materials used in aircraft interiors. It provides guidelines for testing and classifying materials based on their reaction to fire.

Materials covered by BS EN4559:2017

This specification covers various materials such as textiles, foams, metals, and composites used in aircraft interiors. These materials are subject to stringent fire safety regulations due to the confined space and potential risks associated with aviation.

Testing methods and criteria

BS EN4559:2017 lays down specific test methods to determine the flammability characteristics of materials. The tests assess factors like ignition resistance, heat release rate, flame spread, smoke generation, and toxic gas emissions. Materials need to pass these tests to ensure they meet the necessary safety standards.

Importance for aviation safety

The implementation of BS EN4559:2017 plays a crucial role in ensuring the safety of passengers and crew members aboard aircraft. By mandating rigorous testing and classification of materials, the standard helps reduce the risk of fires and mitigate the potential harm caused by smoke, toxic gases, and rapid spread of flames in case of an emergency.

In conclusion, BS EN4559:2017 serves as a vital benchmark for the flammability performance of materials used in aircraft interiors. Its comprehensive testing methods and criteria contribute significantly to the overall safety of aviation operations, protecting lives and minimizing property damage.
