CALIFORNIA TECHNICAL BULLETIN 133

FLAMMABILITY TESTING OF FURNITURE MANUFACTURED 
FOR USE IN PUBLIC BUILDINGS

CAL TB133 is a full-scale fire test for a complete piece of furniture manufactured for use in public 
buildings.  It covers facilities such as prisons and jails, licensed child care facilities, auditoriums 
and theaters, stadiums, board and care homes, hospitals, public assembly areas of hotels and 
motels, old age convalescent homes, commercial and government office buildings and health care 
facilities.  This is not a component test and the standards do not specify how to construct furniture, 
only how they should perform when tested by using the CAL TB133 Procedure.  If you have 
component testing to be performed, see our full A2LA (American Association for Laboratory 
Accreditation) Scope of Accreditation.

In several states in the U.S., the U.K., and parts of Europe, CAL133 or equivalent has been 
adopted as the legal fire standard of flame resistance in commercial furniture.  An investigation 
by the Fire Marshall’s office will include inspection of all furniture and if found to be in noncompliance 
to CAL TB133, the furniture manufacturer and facility owner could be found liable.

TouchStone Systems is A2LA Accredited to CAL TB133.  We not only test your product, we try 
to provide enough information and input to assist you in solving problems in the event of a failure.
  We provide full comprehensive test reporting, along with a video, showing front, side and back 
views of the product during burn, which gives you more data on the travel of the burn and 
its main fuel source.  We also encourage you to have your key personnel witness the testing
first-hand, which  gives a close-up understanding of how the structure, components
and workmanship  of the product can greatly affect the test result.

Realizing your sensitive schedules, we provide fast turnaround of tests and reports.
