Environmental protection level is a European environmental protection standard, which is divided into three levels: Eo, E 1 and E2, and its standard is expressed in numerical values. At present, the international formaldehyde limit level is divided into three levels: E2, E 1 and E0, namely E2≤5.0mg/L and E1≤/0.5 mg/L..
It can also be said that it is the amount of formaldehyde released per liter of air. Eo is an international standard, which is very environmentally friendly. E 1 is the national standard.
At present, only Finland and Japan implement similar E0 standards in the world, and the home products that meet this standard are the top environmental protection products in the world.
European E0 standard refers to stricter environmental protection standards spontaneously formulated by European wood-based panel manufacturers, and is an internal regulation spontaneously formulated by foreign wood-based panel manufacturers to promote industry progress. The formaldehyde emission is less than half of E 1 grade, that is, the formaldehyde emission is less than or equal to 0.5 mg /L!
Therefore, reaching the national standard E 1 is the best in China at present.
