flammability standard requirements for upholstered furniture
WHAT IS TB-117?
TB 117-2013, the latest CAL-117 Tech Bulletin, is a flammability standard for upholstered furniture. It mandates that, beginning January 1, 2015, all filling materials (ie. foam) in California must meet the smolder-resistant requirements of the TB 117-2013 Resilient Filling Material Test. This tests the flammability resistance of the inner materials.
TB-117 APPLICATION AT VIA SEATING
All via seating product manufactured with via seating in-stock fabrics meet the requirements of CAL-117.
COM & TB-117
COM fabrics are not guaranteed to pass CAL-117. Please contact the COM supplier directly to determine the flame-retardant nature of any COM supplied to via seating.
WHAT IS TB-133?
The Bureau of the United States, Consumer Products Safety Commission (CPSC) sets the standard for flame retardance in its TB-133. In this technical bulletin is the Flammability Test Procedure for Seating Furniture for Use in Public Occupancies. Unlike TB-117, TB-133 tests the entire chair.
TB-133 APPLICATION AT VIA SEATING
The chairs available at via seating, unless otherwise specified, do not meet TB-133. Most via seating chair models can be prepared to meet the flame-retardant requirements of TB-133 and the Boston Fire Code. In order to comply with these fire codes, via seating must upholster the chair with a flame-retardant material (i.e. Kevlar® or equivalent). Additionally, most plastic components (i.e. seat pan, back shell, shrouds, etc.) must be either removed or completely upholstered with a flame-retardant material.
Please note, any chair models specified to comply with TB-133 may not resemble what has been photographed and shown in marketing materials. via seating is not responsible for determining the requirement of TB-133 compliance. Check with your local building departments to determine if TB-133 is required on your order. To specify TB-133 on via seating chairs, please refer to the optional add on found by series’ pricing pages within this price book, when applicable.
COM & TB-133
Additional COM/COL is required for TB-133. Please send in COM/COL requirements for seat/back cushions and the back shell. See the price book for more details.
