This standard describes a method for the determination of formaldehyde emissions from building panels by the drying method. This method is suitable for assessing the release level of formaldehyde in different building panels, ensuring that the impact of building materials on indoor air mass during use is within an acceptable range. The standard specifies Sample Handling, testing equipment and operating procedures to guarantee the accuracy and repeatability of results. This method is useful for building material producers and users to control and monitor formaldehyde emissions and promote the use of environment-friendly building materials.
