Champ d’application

This standard applies to the production, inspection, and trade of various types of wood-based panels and their products used for interior decorating and refurbishing. It covers materials such as plywood, particleboard, blockboard, and engineered wood products including wooden flooring, wooden doors, and wall panels. It is specifically designed for materials intended for indoor use.

Exigences techniques

This standard specifies the formaldehyde emission limits for wood-based panels and their products, categorizing them into two primary compliance tiers. Products must meet either the E0 or E1 emission limit criteria based on their specific classification as either a wood-based panel or a wood-based panel product. The standard also details the limit labeling requirements, ensuring that compliant products are properly marked according to their respective emission tiers. Manufacturers must ensure their products meet these tiered limits to be legally sold for interior applications in China. Additionally, the standard introduces requirements for production quality control, allowing manufacturers to use alternative testing methods provided they establish a correlation with the standard's primary testing method.

Méthodes d’essai

The primary testing method defined in this standard is the 1m³ climate chamber method. The testing procedure involves specific specimen preparation, including edge sealing with formaldehyde-free aluminum tape, and strict pretreatment conditions involving controlled temperature, humidity, and air exchange rates. Sampling begins after 48 hours, with specific intervals to determine the stable state of formaldehyde release. Compliance is determined by the average concentration of the final four measurements. Alternative methods for production quality control, such as the perforator, desiccator, gas analysis, and chamber methods, are also referenced in the informative annex.
