This International Standard specifies a test method for determining the equilibrium concentration of formaldehydefrom formaldehyde-emitting coatings and melamine foams in a small test chamber.It describes the determination of the equilibrium concentration of formaldehyde that is established in air at 23 °C and50 % relative humidity. The test closely simulates practical conditions and can be performed on a laboratory scale.Good correlation is obtained with values obtained on samples of the same material in a 40 m3 test chamber. Themethod, which is simple to perform, is therefore suitable for the preliminary determination of limits that have to beadhered to.
