FLAMMABILITY STANDARD REQUIREMENTS FOR UPHOLSTERED FURNITURE

 

TB117-2013

 

WHAT IS TB117-2013?

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 (i.e. foam) in California must meet the smolder-resistant requirements of the TB 117-2013 Resilient Filling Material Test. These test methods are intended to estimate the performance of upholstered furniture under conditions of exposure to a smoldering cigarette and the flammability resistance of the inner materials.

TB133

 

WHAT IS TB133?

Technical Bulletin 133 is a test procedure designed to test seating furniture subjected to ignition sources that may be typical of arson, incendiary fires, or common accidental fires in public buildings. Unlike TB 117-2013, TB-133 tests the entire chair. TB 133 has been repealed by California’s Bureau of Electronic and Appliance Repair, Home Furnishings and Thermal Insulation, effective January 22, 2019.

A recent change to the Boston Fire Prevention Code removes the requirement for furniture to comply with California Technical Bulletin 133 (Cal TB 133) in a fully sprinklered buildings; however, if the
assembly space is not sprinkler protected, compliance with CAL TB-133 is still required in the City of Boston.

Additionally, most plastic components (i.e. seat pan, back shell, shrouds, etc.) must be either removed or completely upholstered with a flame-retardant material.
