Interior Floor Coatings; Paints and varnishes (including enamels and lacquers) based on synthetic polymers or chemically modified natural polymers, dispersed or dissolved in a non-aqueous medium; solutions as defined in Note 4 to this Chapter (HS 3208); Paints and varnishes (ICS 87.040)
National Standard of the P.R.C., Limit of Harmful Substances of Interior Floor Coatings (22 page(s), in Chinese)
The standard specifies the terms and definitions, product classification, requirements, test methods, inspection rules, package and label for substances that are harmful to the human body and the environment in interior floor coatings. This standard includes three types of interior floor coatings: water-based floor coatings, solvent-based floor coatings and solvent-free floor coatings. In this standard, for water-based floor coatings, volatile organic compounds (VOC), free formaldehyde, sum of four kinds of derivatives of benzene, sum of glycol ether ester, sum of free TDI and HDI, four kinds of soluble heavy metals (Pb, Cd, Cr, Hg) are limited. For solvent-based floor coatings and solvent-free floor coatings, VOC, benzene, sum of methyl benzene , dimethyl benzene and ethyl benzene, sum of free TDI and HDI, sum of glycol ether ester, six kinds of phthalates and four kinds of soluble heavy metals(Pb, Cd, Cr. Hg) are limited.
