Formaldehyde Emission Standards of Wood-Based Panel
Because of the hazard for the formaldehyde to human health, many countries establish the formaldehyde emission requirements and testing methods of formaldehyde emission from wood-based panel.
Wang et al. and Luo conducted a comparative study on different testing methods on formaldehyde emission of wood-based panel among China, the European Union (EU), the United States, and Japan. The current EU standards related to formaldehyde emission include one emission standard, 4 product standards, and 4 method standards. The United States has 2 regulations, 3 product standards, and 3 method standards related to formaldehyde emission. Japan has 4 product standards and 4 method standards. Chinese national standards of formaldehyde emission include an emission standard: “GB 18580-2001 Indoor decorating and refurbishing materials-Limit of formaldehyde emission of wood-based panels and finishing products,” more than 50 product standards, and 3 method standards (see Table 1).
