Plate formaldehyde content of the national standard ≤ 1.5mg / l is what it means
National standards, plate content must be lower than the number of units.
Formaldehyde emission is less than 0.5mg, in line with the European E0 level standards;
Formaldehyde emission is less than 1.5mg, in line with European E1 standard.
China's current national standards for wood-based panel is E1 level, there is no E0 level of the so-called E0 level is the Japanese wood-based board substrate standards, which requires formaldehyde emission ≤ 0.5mg / L.
"Indoor decoration materials, wood-based panels and their products in the formaldehyde emission limit" national standards for formaldehyde emission limits of wood-based panels are divided into El (not more than 1.5mg / L dryer), and E2 (not more than 5.0mg / L, dryer method) two levels.
E1 board can be used directly for indoor, E2 board must be decorated to allow for indoor use.
The use of E2 or El standard wood, does not mean that does not contain formaldehyde, but the low content of formaldehyde.
E1, E2 level standard is China's wood-based panel of harmful substances in the limits of the control index, that is, E1-free formaldehyde content ≤ 9mg / 100g, E2 level of free formaldehyde content ≤ 30mg / 100g.
European countries and Japan according to the content of free formaldehyde in wood-based panels to determine a standard E0 grade formaldehyde content, ≤ 3mg / 100g. (Another calculation standard: E1 level ≤ 1.5mg / L, E0 ≤ 0.5mg / L).
