The test method specifies determination of formaldehyde release by the gas analysis method. A test piece of known surface area is placed in a closed chamber in which the temperature, humidity, airflow, and pressure are controlled to defined values. Emitted formaldehyde from the sample is mixed with air in chamber and air is continually drawn from the chamber and passes through gas wash bottles filled with distilled water. After constant time the concentration of formaldehyde in water is determined photometrically. Formaldehyde release is evaluate on the basis of the concentration in water, time and the sample’s dimensions. The result is expressed in milligrams per square meter and hour (mg/m2h)
