How to determine if the material of a luxury conference table is environmentally friendly?

The key to determining whether the material of a luxury conference table is environmentally friendly lies in identifying its environmental certification mark and understanding the specific requirements of different standards. The following are key judgment methods and comparison of mainstream environmental protection levels:
1、 View the authoritative environmental certification logo
Chinese E-level standard
E1 level: Formaldehyde emission ≤ 0.124mg/m ³ (mandatory national standard line).
E0 level: formaldehyde emission ≤ 0.050mg/m ³ (some merchants advertise, but it should be noted that the new national standard has canceled this level).
ENF level: Formaldehyde emission ≤ 0.025mg/m ³ (the highest level in the new national standard, edge sealing detection).
Japanese F-star standard
4-star rating: Formaldehyde emission ≤ 0.03mg/L (without edge sealing detection, one of the most stringent internationally recognized standards).
Other international certifications
CARB certification in the United States: strict requirements for production processes, P2 level is the formaldehyde emission limit standard for composite wood products.
NAF certification: requires no formaldehyde addition throughout the production process.
2、 Combining testing reports with physical observations
Request for testing report: Merchants are required to provide testing reports from authoritative institutions at or above the provincial level to confirm whether the formaldehyde emission data meets the labeled level.
Observing physical details:
The surface coating is uniform and free of pungent odors.
The edge of the board is tightly sealed, and the adhesion of the veneer is high (reducing formaldehyde emissions).
