8.3 Butane flame test

  8.3.1 Light the butane emerging from the burner tube, adjust the gas flow to the appropriate rate (see 5.3) and allow the flame to stabilize for at least 2 min.

  8.3.2 Position the burner tube axially along the junction between the seat and back so that the flame is not less than 50 mm from the nearest side edge, or from any marks left by any previous test, and simultaneously start the clock.

  8.3.3 Allow the gas to burn for a period of 20 ± 1 s, then terminate by carefully removing the burner tube from the test pieces.

  8.3.4 Observe for flaming or progressive smouldering (see clause 2) in the interior and/or cover. Disregard flames, afterglow, smoking or smouldering that cease within 120 s of the removal of the burner tube.

  8.3.5 If flaming or progressive smouldering of the upholstery components is observed, extinguish the test piece. Record a fail result for the butane flame ignition source test.

  8.3.6 If flaming or progressive smouldering is not observed, repeat the test at a fresh position, as described in 8.3.2. If flaming or progressive smouldering is not observed in this retest, record a pass result for the butane flame ignition source test unless the test piece fails the final examination specified in 8.4. Otherwise extinguish the test piece and record a fail result.
