Drs. Mauro Zammarano, William M. Pitts, Anthony Hamins, and Richard Gann of the Flammability Reduction Group submitted comments for consideration to the State of California on a proposed rulemaking action that would eliminate the Technical Bulletin 133 test standard (TB 133 - Flammability Test Procedure for Seating Furniture for Use in Public Occupancies) and accompanying label requirements. Remaining in place would be Technical Bulletin 117-2013 (TB 117-2013 – a test for the smolder resistance of materials used in upholstered furniture) .
Listed in the letter of comments (hyperlink) are statements from the published notice of the proposed action and associated scientific comments. The Flammability Reduction Group provides these comments to offer scientific feedback on statements made in the proposed rulemaking.
Recently, bills have been proposed – Senate bill S.1341 (introduced May 7, 2019) and House bill HR 2647 (introduced May 9, 2019) – to adopt California’s Technical Bulletin 117-2013 as a federal flammability standard.
The Flammability Reduction Group drafted this letter as part of its continued commitment to reduce the flammability risk of Residential Upholstered Furniture (RUF). This effort is a key goal the Reduced Flammability of Residential Upholstered Furniture and Flammability Reduction Technologies Projects.
