--- GB 18583-2001. Interior decoration materials Adhesives harmful substances

1 Scope

One of the ten mandatory Chinese standards on the harmful substances in indoor decorating materials, this one covering the adhesives - the solvent based contact glues, the polyurethanes and the water based products used to lay flooring, fix panels and bond skirting, which are applied wet over large areas in a closed room and then go on releasing into it for months. It specifies the limits of the harmful substances in the adhesives used for interior building decoration and the methods for determining them, and it applies to the adhesives used in interior building decoration. The substances limited are the free formaldehyde, the benzene, the sum of toluene and xylene, the free toluene diisocyanate of the polyurethane adhesives, the halogenated hydrocarbons and the total volatile organic compounds, with the limits set separately for the families of adhesive, since a solvent based product and a water based one cannot be held to the same figure. What gives the document its weight is not the short requirements clause but the six normative annexes behind it, each a complete analytical method: the free formaldehyde by acetylacetone spectrophotometry, the benzene by gas chromatography, the toluene and xylene by gas chromatography, the free toluene diisocyanate of polyurethane adhesives by gas chromatography, the halogenated hydrocarbons by gas chromatography, and the total volatile organic content. Together they occupy four fifths of the standard and are what a testing laboratory actually buys it for. The volatile matter is determined in accordance with GB/T 2793-1995 and the density in accordance with GB/T 13354-1992. Issued on 24 September 2008 and in force since 1 September 2009, it replaces GB 18583-2001.

This standard specifies the architectural interior decoration adhesive limit of harmful substances and test methods. This standard applies to interior decoration with construction adhesive.
