TEST FOR THE IGNITABILITY OF COMPLETE FURNITURE ITEMS WITH THE METHODS ACCORDING TO BS 5852
Principle of the test. A complete item of furniture is subjected to ignition tests with the ignition source:
- within the seating area;
- at floor level outside the seating area adjacent to a vertical surface or beneath an overhang;
- at floor level underneath the test specimen.
Where doubt exists as to which is the most vulnerable test zone, all such positions shall be tested. Furniture containing loose cushions shall be tested with the loose cushions in the normal use position. In each of these tests the most vulnerable zones are tested. The zones are first tested using a smouldering cigarette and then either flaming ignition sources of progressive intensity or a single specified flaming source.
Stand for testing the ignitability of complete furniture items
For furniture tip-up seats; in addition to the tests carried out for the reduced-seat system (lower position), tests must be carried out in an arrangement with the raised seat.
Deliberate ignition. If an item of furniture is required to be resistant to deliberate ignition by small flaming sources representing hand-held matches or cigarette lighters applied to the underneath of a test specimen, then butane flame ignition sources 1 and/or 2 and/or 3 shall be applied to the most vulnerable zone.
Evaluation of results. If the ignition sources no progressive smouldering ignition or flaming ignition of any element of the complete furniture items is observed, the result of the test of this system shall be considered positive.
Test samples. Two complete seats
