TB 133 Flammability Test for Seating Furniture for Use In Public Buildings
 - Standard Brief:
 
A. This test procedure is designed to test seating furniture for use in occupancies that are identified as or considered to be public occupancies. Such facilities might include, but are not limited to, jails, prisons, nursing care homes, health care facilities, public auditoriums, hotels and motels.
 
B. This test procedure is not intended to be used for the evaluation of residential furniture.
 
C. It is the intent of the Bureau that furniture complying with Technical Bulletin 133 be safer furniture when subjected to the ignition source specified by this test. This type of ignition may be typical of arson or incendiary fires or common accidental fires in public buildings. This Bureau expects manufacturers attempting to comply with this standard will also seek to make safer furniture, and will not attempt to compromise the intent of the standard in any manner.
