How can a furniture manufacturer comply with TB 133?
A. There are two basic methods of compliance with TB 133. One method is to find a compatible selection of components, which, when assembled, work well together under the test conditions of TB 133. Since TB 133 is a fire-performance test of finished furniture, or furniture “mock-ups,” no components can claim to be in compliance, nor are there any recommended components or material specifications. Since TB 133 is based solely on fire performance, a furniture manufacturer is permitted to make furniture in any manner he or she wishes, provided that the furniture complies with the test criteria of TB 133. The second basic method of compliance would be by use of an interliner or fire-blocking layer. There are a number of excellent materials available for this purpose. There may be advantages and disadvantages in using this approach. Depending upon the type of blocking layer selected, a double upholstery process may be required and a fire-resistant thread will be needed to sew cushions, etc.
