This British Standard specifies requirements for flexible loadbearing combustion modified, polyurethane cellular materials, manufactured in block, sheet and strip form, in moulded and fabricated shapes and as reconstituted material.

[A1_start] Materials defined as combustion modified are those that meet the legal and technical requirements of the Furniture and Furnishings (Fire) (Safety) Regulations 1988 [1], the Furniture and Furnishings (Fire) (Safety) (Amendment) Regulations 1989 [2] and the Furniture and Furnishings (Fire) (Safety) (Amendment) Regulations 1989 [3] for use in domestic upholstered furniture, mattresses and bed bases. [A1_end]

In addition to the definitive requirements, this standard also requires the items detailed in Clause 3 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.
