HDB/V

The model HDB is the standard test apparatus.
To determine the flame behaviour of construction and insulation materials, the burner with a 20 mm flame is manually guided to the test specimen. 

In this case, the burner automatically pivots into the inspection position of 45°. After the relevant flaming time it is to pull back. A test time control emits acoustic signals for the flame and the observation time. The examiner can fully focus on the flame development.
