Facts on Flammability

Slide 13 of 37

For upholstered furniture, several small scale composite testing procedures are used today. One is California Technical Bulletin 117 which uses a small chair mockup configuration with one horizontal “seat” surface and one vertical “back” surface, a standardized cotton fabric, and a smoldering cigarette placed at the intersection of the two surfaces. For this case a “pass” means that there is no continuing smolder and the sample weight loss does not exceed 20%.

The voluntary standard by UFAC, the Upholstered Furniture Action Council, is similar to TB 117 using a different fabric. It further uses a standard foam to test variations in fabric performance.

There are also a number of other proposed procedures developed by the National Institute of Standards and Testing (NIST) using larger samples and more complex constructions and more cigarettes.
