The
California Technical Bulletin 117 (TB 117) standard was born in California and it had its last revision in 2013.
The technical standard applies to upholstered furniture
(intended for seating), not to bedding products such as mattresses, pillows and decorative cushions for which other requirements exist.
From 25 June 2021 this rule has been extended to all of the USA.What does the standard prescribe?
The test involves the application of a series of cigarettes on a
composite made up of the
test material, supplied by the customer, and other
standard materials defined by the Californian regulator. Basically it is a resistance to the consumption of a cigarette which must not cause flames or other phenomena typical of flameless combustion (for example incandescence).
The standard requires the evaluation of the following types of materials:
1.
cover fabric of any kind (section 1);
2.
barrier materials or materials that can be of various kinds and which act as a barrier between the covering and the padding materials (section 2);
3.
resilient filling materials which can be of various kinds (section 3);
4.
decking material if they are placed under removable cushions (section 4).
In order to produce upholstered seats compliant with TB 117-2013, one of these two solutions can be adopted:
- use a cover compliant with section 1 and combine it with filling materials compliant with section 3 (in this case, a barrier material is not needed);
- use a cover and/or filling materials even if they do not comply with the respective sections, therefore not "fireproof", provided that a barrier material compliant with section 2 is interposed;
- if present, the resilient filling materials of the seat base, if they are placed under removable cushions, must comply with section 4.
These solutions concern all the upholstered parts of the piece of furniture: seat, backrest, armrests, sides, etc.
Upholstered furniture manufacturers are responsible for the compliance of their products with TB 117-2013 and therefore are required to demonstrate that the requirements are met.
