Chapter 4 of this standard is compulsory, while the rest are recommendatory.
This standard is developed in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB 18580-2001 Indoor Decorating and Refurbishing Materials - Limit of Formaldehyde Emission of Woodbased Panels and Finishing Products.
The following technical changes have been made with respect to GB 18580-2001:
——Classification is cancelled;
——1 m3 chamber test method is modified and changed to footnote;
——40 L desiccator method and limits are cancelled; the limits of (9~11) L desiccator method and perforator method are cancelled;
——(9~11) L desiccator method and perforator method are used for production quality control only;
——Gas analysis method is added for production quality control;
——The provisions of inspection rules are modified;
——The provisions of product marking are cancelled.
In this standard, the 1 m3 chamber test method for formaldehyde emission is consistent with ISO 12460-1: 2007 Wood-based Panels - Determination of Formaldehyde Release - Part 1: Formaldehyde Emission by the 1-cubic-metre Chamber Method, and the limits are basically consistent with those specified in corresponding parts of ISO 16893: 2016 Wood-based Panels - Particleboard and ISO 16895:2016 Wood-based Panels - Dry-process Fibreboard.
This standard was proposed by the State Forestry Administration of the People's Republic of China.
This standard is under the jurisdiction of National Technical Committee on Wood-based Panels of Standardization Administration of China (SAC/TC 198).
The previous editions of this standard are as follows:

Indoor Decorating and Refurbishing Materials - Limit of Formaldehyde Emission of Wood-based Panels and Finishing Products
1 Scope
This standard specifies the requirements, test methods ), judgment rules and test report of the limit of formaldehyde emission of wood-based panels and finishing products for indoor decorating and refurbishing.
This standard is applicable to the limits of formaldehyde emission of all kinds of indoor wood-based panels and finishing products, such as fiberboard, chipboard, veneer plywood, block board, core-board, multilaminar decorative lumber, laminated veneer lumber, glued laminated timber, decorated wood-based panel, wooden flooring, wood-based wall-board, wooden door and window, etc.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/T 18259-2009 apply.
4 Requirements
Limit of formaldehyde emission of woodbased panels and finishing products for indoor decorating and refurbishing materials is 0.124 mg/m3 and is identified as E1.
5 Test Methods
5.1 In accordance with the requirements of 1 m3 chamber test method for determination of formaldehyde emission in 4.60, GB/T 17657-2013.
5.2 Dimensions of specimens: length l=(500±5)mm, width b=(500±5)mm. Quantity of specimens: two pieces; surface area of specimens: 1 m2. Where the length and width of the specimens are less than the required dimensions, they may be spliced by the method that doesn’t affect the determination results.
6 Judgment Rules
For the purpose of this standard, if test results meet the requirements of limit, the specimen shall be judged as acceptable.
