Formaldehyde has always been an important chemical substance that pollutes the environment and harms human health. It is also a synthetic material additive that people have always criticized. Because formaldehyde is harmful to the human body, the country has clear regulations and industry standards for the formaldehyde content of synthetic materials. Commonly used formaldehyde content detection standards are as follows: 1. Wood EN 120:1992 'Determination of Formaldehyde Content in Wood Boards—Perforation Extraction Method' Scope of application: Non-laminated boards and uncoated wood boards: particleboard, medium density fiberboard. BS EN 717-1: 2004 'Determination of Formaldehyde Emission in Wood Boards: Part One: Determination of Formaldehyde Emission by Air Chamber Method' Scope of application: all types of boards. BS EN 717-2: 1994 'Determination of Formaldehyde Emission in Wood Boards: Part 2 Determination of Formaldehyde Emission by Gas Analysis Method' Scope of application: All types of boards. BS EN 717-3: 1996 'Determination of formaldehyde emission in wooden boards: Part 3 Determination of formaldehyde emission by flask method' Scope of application: uncoated wooden boards. GB 18580: 2001GB u0026 GB 17657:19991), GB/T 17657-4.11(1999) 'Limit of Formaldehyde Release in Artificial Panels and Products of Interior Decoration Materials-Perforated Extraction Method' Scope of application: medium density fiberboard, high density fiberboard, Particleboard, Oriented Strand Board, etc.; 2), GB/T 17657-4.12 (1999) 'Limit of Formaldehyde Release in Artificial Panels and Products of Interior Decoration Materials—9~11L Dryer Method' Scope of application: plywood, decorative veneer veneer Plywood, blockboard, etc.; 3), GB/T 17657-4.12 (1999) 'Limit of formaldehyde emission in interior decoration material wood-based panels and their products—40L Dryer Law' Scope of application: decorative wood-based panels (including impregnated paper Laminated wood flooring, solid wood composite flooring, bamboo flooring, impregnated adhesive film paper veneer wood-based panels, etc.). GB 18584:2001 'Limit of Hazardous Substances in Wooden Furniture of Interior Decoration Materials-Dryer Law' Scope of application: wood-based panels. ASTM D 5582: 2000 'Test Method for Formaldehyde in Wood-Dryer Method' Scope of application: wood products-containing urea-formaldehyde resin adhesives, including plywood, hardwood, particleboard, and medium-density fiberboard. JIS A 1460: 2001 'Determination of Formaldehyde Emission from Building Materials Boards—Dryer Method' Scope of application: Building materials boards. Two: Textiles BS EN ISO 14184-1: 1999 'Determination of Formaldehyde in Textiles: Part One Free and Hydrolyzed Formaldehyde (Water Extraction Method)' BS EN ISO 14184-2: 1999 'Determination of Formaldehyde in Textiles: Part Two Formaldehyde Release Content (vapor absorption method)' JIS L 1041 'Determination of formaldehyde content in resin-treated textiles' AATCC 112:2003 'Textile volatilization of formaldehyde, determination: sealing method' GB/T 2912.1 'Determination of formaldehyde in textiles Part 1: Determination of Free Hydrolyzed Formaldehyde (Water Extraction Method)' GB/T 2912.2 'Determination of Formaldehyde in Textiles Part 2: Formaldehyde Release (Vapor Absorption Method)' 3: Leather ISO17226-2:2008 'Determination of Formaldehyde Content in Leather Chemical Test Spectroscopy Photometric method' GB/T19941-2005 'Leather and fur chemical test
