本国际标准规定了在小型试验箱中测定甲醛释放涂料和三聚氰胺泡沫中甲醛平衡浓度的试验方法。它描述了在23°C和50%相对湿度下空气中甲醛平衡浓度的测定。该测试密切模拟实际条件，可以在实验室规模上进行。与在40 m3试验箱中获得的相同材料样品的值获得了良好的相关性。该方法执行简单，因此适用于必须遵守的限值的初步确定。

This International Standard specifies a test method for determining the equilibrium concentration of formaldehyde
from 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 and
50 % 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. The
method, which is simple to perform, is therefore suitable for the preliminary determination of limits that have to be
adhered to.
