Finding F-0018

“The Chinese E1 corresponds to the European E1 (0.124 mg·m−3 air), while the Chinese E0 refers to panels with formaldehyde emissions higher than 0.025 mg·m−3 air but not exceeding 0.050 mg·m−3 air.”

Structure

Source: Wood-based panels (particleboard, MDF, plywood)
Factor: Formaldehyde (CH₂O)
Study design: narrative review of production, emissions and regulation (class 5)
Effect: limit 0.050
Jurisdiction: China (E0) and European Union (E1)
Flags: primary-missing
Caveat: Chinese class E0 upper bound; the European class E1 in the same sentence is 0.124 mg·m−3; the standards themselves are not in the library
