What are the commonly used standards for formaldehyde detection?
Formaldehyde has always been an important chemical substance that pollutes the environment and damages human health. It is also a synthetic material additive that people have been criticizing for a long time. Because formaldehyde is harmful to the human body, the state has clear regulations and industry standards for the formaldehyde content of synthetic materials. ( The commonly used test standards for formaldehyde content in Hong Kong) Co., Ltd. are as follows: 1: Wood EN 120:1992 'Determination of Formaldehyde Content in Wood Boards'—Scope of application of perforated extraction method: Unlaminated and uncoated wood boards: particleboard, medium density fiberboard. BS EN 717-1: 2004 'Determination of formaldehyde emission from wood panels: Part 1 Determination of formaldehyde emission by air chamber method' Scope of application: All types of wood panels. BS EN 717-2: 1994 'Determination of Formaldehyde Emission from Wood Panels: Part II Determination of Formaldehyde Emission by Gas Analysis' Scope: All types of wood panels. BS EN 717-3: 1996 'Determination of Formaldehyde Emission from Wood Panels: Part III Determination of Formaldehyde Emission by Flask Method' Scope of application: Uncoated wood panels.

GB 18584:2001 'Limiting Hazardous Substances in Wood Furniture for Interior Decoration Materials-Dryer Law' Scope of application: wood-based panels. ASTM D 5582: 2000 'Test Methods for Formaldehyde in Wood - Dryer Method' Scope of application: Wood products - Adhesives containing urea-formaldehyde resins, including plywood, hardwood, particleboard, medium density fiberboard. JIS A 1460: 2001 'Determination of formaldehyde emission from building materials panels—Scope of application of the 'Dryer Law': building materials board. Two: Textiles BS EN ISO 14184-1: 1999 'Determination of Formaldehyde in Textiles: Part 1 Free and Hydrolyzed Formaldehyde (Water Extraction Method)' BS EN ISO 14184-2: 1999 'Determination of Formaldehyde in Textiles: Part II Release of Formaldehyde Content (vapor absorption method) 'JIS L 1041 'Determination of formaldehyde content in resin-treated textiles' AATCC 112:2003 'Volatile formaldehyde in fabrics, 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 II: Release of Formaldehyde (Steam Absorption Method)' III: Leather ISO17226-2:2008 'Determination of Formaldehyde Content in Leather Chemical Test Spectroscopic Photometric method GB/T19941-2005 'Determination of formaldehyde content in chemical tests of leather and fur Spectrophotometric method' IV: Paper EN645: 1993 + EN1541: 2001 'Paper and cardboard in contact with food - cold water extraction method' EN647: 1993 + EN1541: 2001 ' Paper and cardboard in contact with food - Hot water extraction method GB 18585: 2001 'Limits of Hazardous Substances in Interior Decoration Materials Wallpaper (Formaldehyde)' 5: Other Coatings GB 18582: 2001 'Hazardous Substances in Interior Decoration Materials and Interior Wall Coatings' Substance Limits 'Building Adhesives GB 18583: 2001 'Limits of Hazardous Substances in Adhesives for Interior Decoration Materials' Melamine ISO 4614: 2000 'Plastics.
