Область применения
This standard applies to adhesives used for indoor decorating and refurbishing materials. It categorizes these adhesives into three main types: solvent-based, water-based, and bulk-type adhesives. It is mandatory for all manufacturers producing adhesives for the Chinese indoor decoration market. The standard does not apply to adhesives used for outdoor applications or industrial manufacturing outside of indoor decoration.
Технические требования
Chapter 3 of GB 18583-2008 is mandatory and specifies the limit values for harmful substances across the three adhesive categories. For solvent-based adhesives (including neoprene, SBS, and polyurethane types), the standard sets strict limits on free formaldehyde, benzene, toluene + xylene, and toluene diisocyanate (TDI). It also regulates specific halogenated hydrocarbons such as dichloromethane and trichloroethylene. For water-based adhesives, the standard restricts the content of free formaldehyde, benzene, toluene + xylene, and total volatile organic compounds (TVOC). Manufacturers must ensure their water-based formulations comply with these specific thresholds to be sold in China. A new category introduced in this version is the bulk-type adhesive, which is subject to a specific limit for TVOC. Furthermore, the standard mandates that packaging labels must clearly indicate the names and maximum content of the regulated harmful substances. Compliance with these labeling requirements is strictly enforced.
Методы испытаний
The standard outlines specific testing methodologies in its normative appendices to verify compliance. Free formaldehyde is measured using the acetylacetone spectrophotometric method (Appendix A). Benzene, toluene, and xylene contents are determined via gas chromatography (Appendices B and C). Toluene diisocyanate (TDI) in polyurethane adhesives is also quantified using gas chromatography with an internal standard method (Appendix D). Halogenated hydrocarbons are tested via gas chromatography (Appendix E), and TVOC is calculated by subtracting water content from total volatiles, determined through oven drying and Karl Fischer titration or gas chromatography (Appendix F).
