EN 1021-1 Furniture – Assessment of the ignitability of upholstered furniture – Part 1: Ignition source smouldering cigarette

1 Scope
This European Standard specifies a test method to assess the ignitability of material combinations, such as covers and fillings used in upholstered seating, when subjected to a smouldering cigarette as an ignition source.
The test measures only the ignitability of a combination of materials used in upholstered seating and not the ignitability of a particular finished item of furniture incorporating these materials. They give an indication
of, but cannot guarantee, the ignition behaviour of the finished item of furniture.

NOTE Test specimens prepared from materials taken from furniture that has been used may give different results to the same materials before use.

2 Terms and definitions

For the purposes of this European Standard, the following terms and definitions apply.

2.1 progressive smouldering
exothermic oxidation, not accompanied by flaming, that is self-propagating, i.e. independent of the ignition source. It may or may not be accompanied by incandescence

2.2 flaming
undergoing combustion in the gaseous phase with the emission of light

2.3 Cover

2.3.1
outer cover outer layer of the upholstery

2.3.2 inner cover
thin layer of material used between the outer cover and the upholstery filling. Any inner cover greater than nominally 2 mm thick is part of the filling for test purposes NOTE The term “interliner” is no longer used because it is non-specific and has been applied to different
components within the composite.

2.4 filling
main upholstery material contained by the outer cover and (if used) the inner cover. It may consist of several different materials including any inner cover nominally greater than 2 mm thick
