The device is used to determine the effect of flames on respi­ ratory protective equipment such as respirators. It is tested whether the specimen starts to burn or whether other hazards may occur for the user.

A specimen is placed in a specimen holder or attached to a test head. In method 2, the specimen is passed over the

burner for a defined period of time and then withdrawn. In method 3, the specimen is then drawn over the propane gas burner, which has a temperature of approx. 800ºC at a speed of 60±5 mm/s. This is done in various burner positions. The burner can be moved in depth for this purpose. The speci­men is moved by a spindle drive on a linear guide.
