TB133

National has you covered with fabrics that help you meet TB133

The TB133 test procedure is designed to test seating furniture for use in occupancies that are identified as or considered to be public occupancies. 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 Bureau expects manufacturers attempting to comply with this standard will also see to making safer furniture and will not attempt to compromise the intent of this standard in any manner.

National provides TB133 testing services for COM (Customer's Own Material), COL (Customer's Own Leather) and Alliance partner upholstery orders. COM, COL and Alliance partner upholstery must first be evaluated for application approval, prior to TB133 approval. National provides pre-approval for TB133 chair/COM fabric combinations. The availability of TB133 on specific chair/alliance fabric combinations can be found at www.NationalOfficeFurniture.com/Alliance. Even though we try to keep this document as accurate as possible, the supplier may change contents, finishes, etc...without our knowledge. Customer needs to confirm that the information on this listing matches the content information from the COM supplier. If no test data is available for a particular fabric/chair combination, the TB133 order will not be allowed. These pre-approved fabrics can be ordered as standard product - no custom quote required.
