This British Standard specifies requirements for flammability of fabrics and fabric assemblies for use in the construction of textile structures such as marquees, large tents, temporary buildings, awnings and other textile structures utilizing large areas of a flexible textile membrane other than air-supported structures, when tested in accordance with test 2B (bottom edge ignition) of BS 5438 : 1989.
Linings and drapes are frequently used in these structures, loose or attached to the outer fabric. In the latter case, the composite fabric assembly is tested to this British Standard.
NOTE. Where the lining or drape is separate from the outer fabric, the standard for curtains and drapes, BS 5867 : Part 2 : 1980 may be appropriate.
These textile structures are normally erected outdoors. Sometimes they are erected in unusual situations, e.g. within buildings, where circumstances may arise where risk assessment is different and other criteria apply.
