Formaldehyde Emission Test Chamber


The test installation is used to determine the discharge of formaldehyde by substances which emit formaldehyde. The test requires a precise, reproducible determination of the possible subsequent formaldehyde discharge by wooden materials and components.

  • The test space air is heated to a constant temperature of +60 °C ±0.5 K and purged continuously with 60 l/h of temperature pre-conditioned air.
  • The components to be tested are deposited in the test chamber. The test chamber is designed as a gastight area.
  • It is temperature conditioned via the walls and a water pump circuit.
  • Leak-proofness of the test chamber is monitored via a pressure sensor and displayed on the touch-panel (operating console).
  • Setting of the overpressure is effected manually by means of a manual control valve (1000 – 1200 Pa).
  • In the test chamber, formaldehyde gas is mixed with the inlet air and led into washing bottles filled with demineralized water via the air outlet. The formaldehyde which has gassed out is dissolved in the water.
  • The routing of the outgoing air is effected by a five-fold distribution with solenoid valves. The air can be released freely into the atmosphere or it is routed via four separate pairs of gas washing bottles (not included in the scope of delivery) which are controlled by a timer.
