The air flow through the heating chamber shall be as uniform and laminar as possible. The test pieces
shall be placed with the smallest surface facing towards the air flow to avoid disturbing the air flow. The
air speed shall be between0,5 m/s and 1,5 m/s.
The air entering from a side-wall air-inlet into the heating chamber is turbulent around the test pieces,
which are suspended on a carrier rotating at a speed of five to ten rotations per minute so that they are
exposed to the heating air as uniformly as possible. The average air speed shall be 0,5 m/s 0,25 m/s.
