according to The standard announcement (No. 3, 2021) issued by the General Administration of market supervision and the State Commission of standards on March 9 formally issued GB / T 39600-2021 classification of formaldehyde emission from wood based panels and its products and GB / T 39598-2021 guide for indoor load carrying capacity of wood-based panels based on the limit of formaldehyde content, which will be implemented on October 1, 2021.

The two standards of "classification of formaldehyde emission from wood-based panels and their products" and "guidelines for indoor loading limits of wood-based panels based on the limit of formaldehyde" are The transformation and application of research results of "wood industry energy saving and consumption reduction and production safety control technology" (Project No.: 2016yfd0600700), a national key R & D project in the 13th Five Year Plan period. The former is jointly completed by 50 units, such as the Wood Industry Research Institute of Chinese Academy of Forestry Sciences and Wanhua Hexiang Board Industry Co., Ltd., while the latter is jointly completed by 45 units including the Wood Industry Research Institute of Chinese Academy of forestry, Sofia home furnishing Co., Ltd., and Dehua Group Holding Co., Ltd.

(1) GB / T 39600-2021 classification of formaldehyde emission from wood based panels and their products

"Classification of formaldehyde emission from wood based panels and their products" stipulates the classification requirements, test methods and determination rules of formaldehyde emission of indoor wood-based panels and their products. According to the standard, the formaldehyde emission of indoor wood-based panels and their products is divided into three categories according to the limited value Three grades, namely E1 level (≤ 0.124mg/m ³)、 E0 grade (≤ 0.050mg/m ³) And enf (≤ 0.025mg/m ³)。 The standard is applicable to the formaldehyde emission classification of various kinds of indoor wood-based panels and their products, such as fiberboard, particleboard, plywood, blockboard, reconstituted decorative wood, veneer laminated timber, laminated timber, veneered wood-based panel, wooden floor, wooden wallboard, wooden door, etc.

This standard is a compulsory national standard The refinement and matching of GB 18580-2017 "formaldehyde emission limits in wood-based panels and their products for interior decoration and decoration materials" can promote the production and promotion of wood-based panels and their products with different environmental protection grades by enterprises, meet the needs of consumers for more environmentally friendly and greener wood-based panels and their products, and lead the technological progress of the industry, Promote the green development and industrial transformation and upgrading of wood-based panel and its products industry.

(2 GB / T 39598-2021 "guidelines for indoor load limits of wood based panels based on limiting formaldehyde content"

The guide to the indoor carrying capacity limit of wood-based panels based on the limit of formaldehyde emission provides the terms and definitions, basic principles, calculation methods and key points to be considered of the indoor bearing limit of wood-based panels based on the limit of formaldehyde emission. It is applicable to indoor furniture, cabinets, wooden doors, wooden wallboards, etc The bearing capacity limit of wood-based panels used in wood products such as wooden floors.

The promulgation and implementation of the standard can provide guidance for consumers to reasonably use wood-based panels in interior decoration and decoration, and it is of great significance to protect consumers' health, eliminate indoor environmental pollution and promote the healthy development of wood-based panel industry.
