Judge Reference: GB/T 39600-2021 Formaldehyde emission grading for wood-based panel and finishing products

Test Conclusion: The tested item meets the requirements of GB/T 39600-2021 standard (Grade E1)

Numerical meaning: The Chinese standard for formaldehyde emission of interior decoration materials (such as GB/T 39600-2021 "Classification of Formaldehyde Emission of Wood-based Panels and Their Products") stipulates that the formaldehyde emission of panels directly used indoors should be ≤ 0.124mg /m³ (this value is an internationally recognized strict limit and is consistent with the EU E1 standard (≤ 0.124mg /m³).
Low hazard risk: The sound-absorbing board, with a formaldehyde emission of ≤ 0.124 mg/m³, exhibits extremely low formaldehyde emissions under normal usage conditions (such as appropriate temperature and humidity), resulting in a minimal impact on indoor air quality. It can significantly reduce respiratory irritation, allergic reactions, or long-term health risks (such as cancer).
Meeting environmental protection requirements: It meets the high standards for indoor air quality in public places, such as schools, gymnasiums, lecture halls, office buildings, hotels, and theaters. It is especially suitable for sensitive groups, including children, pregnant women, and the elderly.
