California TB 133 Flammability Test Procedure for Seating Furniture for Use in Public Occupancies

California TB 133 Flammability Test Procedure for Seating Furniture for Use in Public Occupancies has been repealed effective January 22, 2019.

TB133 was an open flame test for upholstered seating, which generally required the use of flame-retardant chemicals and additional upholstery operations to apply barrier materials.

The BIFMA Flammability Subcommittee was active in initiating the repeal process for TB133 several years ago. Their members participated in numerous meetings with stakeholders including: the scientific community, firefighters, environmentalists, government agencies, and other stakeholder associations.

Given the impact of TB133 to the furniture industry, BIFMA took the lead on the repeal project with presentations, cost studies (from California), surveys, statistical reviews of fire data, and other activities that proved the repeal an appropriate decision for California.
