Sheet Standard

- May 15, 2019-

1. EU standards

European Standard BS EN 13986:2004 "Performance, Conformity Assessment and Marking of Artificial Panels for Construction"

There are specific indicators and methods for the detection of formaldehyde emission in E1 grade and E2 grade wood-based panel products. The E1 standard is 8 mg/100 g; the E2 standard is 30 mg/100.

Another method is gas analysis: E1 grade release of 3.5 mg/m2h, or 5 mg/m2h (within 3 days of production); E2 grade of 3.5-8 mg/m2h, or 5-12 mg/m2h.

2. National mandatory standards

GB18580—2001 “Release release limit for wood-based panels and their products in interior decoration materials”: E1 grade: 9mg/100g (can be used directly indoors), E2 grade: 30mg/100g (allowed to be allowed after finishing treatment) Indoors). Alternatively, the detection method is a 40L dryer method with an E1 level of 1.5 mg/L and an E2 level of 5.0 mg/L. The detection method is a 40 L dryer method.

3. California CARB Standard

Since January 1, 2010, California has adopted the P2 standard, namely

1. Hardwood plywood with single core: formaldehyde emission is less than or equal to 0.05 ppm

2. Hardwood plywood with composite core: formaldehyde emission is less than or equal to 0.05 ppm

3. Particleboard: Formaldehyde release limit value is less than or equal to 0. Wardrobe.09 ppm

4. Medium density fiberboard: formaldehyde emission is less than or equal to 0.11 ppm

5. Thin medium density fiberboard: formaldehyde emission is less than or equal to 0.13 ppm

4. Japanese agricultural standards

Japanese veneered wood-based panels (including impregnated paper laminated wood flooring, solid wood composite flooring, etc.) adopt the Japanese agricultural standard, requiring 40L dryer test, the grade of the plate is F4 star, F3 star, F2 star, F1 Star four-level wardrobe, the most stringent F4 star (average 0.3 mg / L, maximum 0.4 mg / L) is not used in China, and F3 star, F2 star, F1 star, corresponding to 0.5mg / L, 1.5mg /L, 5.0 mg/L.
