GB/T 34722-2017 is a standard related to indoor air quality and formaldehyde emission from wood-based panels. The standard sets limits on formaldehyde emission from various types of wood-based panels, including particleboard, MDF, plywood, and blockboard. The formaldehyde emissions limit depends on the type of panel and the intended use of the panel. For example, the formaldehyde emission limit for particleboard used for interior decoration and furniture should be less than or equal to 0.124 mg/m3. It is important to note that these limits are based on testing of the panels in a controlled laboratory environment and real-world emissions may vary depending on installation and use conditions.
