It is understood that the most obvious change of the new standard is to increase the requirement of formaldehyde emission limit. The formaldehyde emission limit is 0.124 mg/m3, and the limit mark is E1. The original E2 level is cancelled and synchronized with international standards.
In addition, the new standard also canceled the detection method of the dryer method and the perforation extraction method in the original standard, which was unified into the “1 cubic meter climate chamber method”.
