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.

The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
