本欧洲标准规定了一种室内方法，其具有三个选择的测试室，用于根据在确定条件下的气候室中的稳态浓度来确定木质板的甲醛释放，其涉及现实生活中的典型条件。通过使用数学模型，这种室法也可以应用于实践中各种条件下甲醛浓度的估计

This European Standard specifies a chamber method with three options of test chambers for the determination of the formaldehyde emission from wood-based panels in terms of the steady-state concentration in a climate chamber under defined conditions, which relate to typical conditions in real-life. This chamber method can also be applied to the estimation of formaldehyde concentrations under various conditions in practice, by the use of mathematical models.
