Fire tests with measurements of temperatures, radiation levels and smoke
production have been carried out using domestic beds fitted with full bedding
materials in a full-scale compartment-corridor.
The tests have included mattresses made of polyurethane of various types,
hair, spring interior and foamed rubber with mattress covers of cotton, flame
retarded cotton or proofed nylon. Some tests with hair or glass fibre cloth
protective interlinings are also recorded.
The study has shown that a rapid development of fire in bed and bedding
materials can take place with certain combinations of mattresses and their covers.
The type of cover is extremely important in the overall fire development
particularly with polyurethane mattresses.
A substantial improvement in the fire behaviour of many of the principal
types of beds tested can be achieved by a careful selection of bedding materials,
such as the type of mattress cover, and in certain cases by the use of protective
interlinings.
