标准摘要
[中文适用范围]： 本国际标准规定了在小型试验室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℃和 50% 相对湿度下空气中建立的甲醛平衡浓度的测定。 该测试紧密模拟实际条件，可以在实验室规模上进行。 与在 40 m 测试室中相同材料的样品上获得的值具有良好的相关性。 该方法执行简单，因此适合于初步确定必须遵守的限值。 [外文原描述]： 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.
