The device is used to determine the flame effect on respiratory protective equipment, such as respirators. It is tested whether the specimen begins to burn or whether other hazards to the user may occur. A specimen is placed in a specimen holder. Testing with a test head is not possible with this instrument. If you require testing with a test head, use the RPD - DIN EN 13274-4 for this purpose. In procedure 2, the specimen is moved over the burner for a defined period of time and then withdrawn. In procedure 3, the specimen is drawn over the propane gas burner, which has a temperature of approx. 800 °C, at a speed of 60±5 mm/s. This is done in various burner positions. The burner can be moved manually in depth for this purpose. The specimen is moved by an electric spindle drive on a linear guide.
