Can plastics, which are used as part of the furniture structure, affect the TB 133 test?
A. Yes, structural plastics can create considerable problems in the TB 133 test, depending on the generic type of plastic used and the location of the plastic on the furniture. It is important for manufacturers to not only address flammability issues relating to fabrics and cushioning materials, but also other component materials, such as structural plastics. These materials may melt and drip during the test, creating a pool of burning molten plastic which may be an added ignition source for the furniture. FABRICS Q. It has been reported that certain fabrics do not perform well in the TB 133 test, and that some cushioning materials are better than others.
