measurement results are almost unaffected by temperature; and climate box method is determined by the release of air to the sample reached a steady state of formaldehyde, the determination is at room temperature get on. The principle of the dryer method is similar to that of the weather box method, which can reflect the amount
of formaldehyde release that can be released during actual use. However, when the temperature is different, the difference between the actually released formaldehyde and the test result is different. In other words, China's current formaldehyde release testing standards for wooden flooring is carried out at room temperature, formaldehyde
emission after the temperature increase is not a clear standard. According to GB18580-001, 'Limit of Formaldehyde Release in Wood-based Panels and Their Products for Interior Decoration', the limit of formaldehyde emission is divided into E1 grade (≤1.5mg / L), E2 grade (≤5.0mg / L) , E0 level (≤ 0.5mg / L), however, this is only
