We received a communication from BIFMA indicating Boston City Fire Code has effectively been changed, for sprinkled occupancies only. Indeed BFD IX-10, the equivalent of California Technical Bulletin 133 – Cal TB 133 for Boston, is no longer required for this specific product use. However compliance to Cal TB 133/BFD IX-10 in Boston as well as in Massachusetts is still required for Assemblies (50+ persons), Educational (up through the 12th grade), Health Care, Residential Board and Care, Dormitories, hotels, Detention and Correctional institutions. The Boston regulation of Upholstered Furniture can be found at: CityOfBoston
Below you can see an infra-red photograph of a chair being tested to CAL 133. Remember: color blue is cold. The brighter the color the warmer it gets. The black spot is because the camera saturates. In photograph #1 you can see the ignition process where the lab technician has set the inverted gas burner 1 inch above the chair seat pan. In photograph #2 you can see the chair burning.
In photograph #3 the chair burning rate has slowed down and the amount of heat released is lower than when the chair was shot in photograph #2. In chair #4 the chair is slowly self-extinguishing; you still can see some hot spots on the backrest and in the seat pan. The information on the seat pan is of particular interest as the hot spot is within the seat pan cushioning, underneath the fire membrane.

My career has been focused on simulating real life in the lab under controlled yet accelerated conditions. My passion for lab testing lead me to start Micom Laboratories Inc. 16 years ago. Through time I made sure Micom has the necessary equipment to simulate various environmental parameters such as the sun, vibrations, heat, cold, thermal shocks and humidity. I wanted to be able to move things back and forth, apply stresses to the products and materials we test and see how they react to the various stimuli. To do so we test products and materials against known standards and specifications (certification) and in many cases by creating my own test protocols and specifications (this is the cherry on top of the sundae…). This is what led me to participate in many standards writing committees and to become chairman of some of these committees.
