The tests are performed in a test cabinet with a calibrated air flow. The cover fabric and the filling are put in a test rig to create a small sofa with a 90o angle between seat and back.

There are six different ignition sources, numbered 2-7. ignition sources 2-3 are gas flames and ignition sources 4-7 are wooden cribs (the higher number the larger gas flame/crib).
