Alcance y aplicabilidad

This standard applies to wallpapers of various base materials used in indoor decorating and refurbishing. It specifies the limits of harmful substances to the human body and the environment. Manufacturers of all types of wallpaper substrates must comply with this standard to enter the Chinese market.

Requisitos técnicos

The standard sets strict mandatory limits for several categories of harmful substances. It defines maximum concentration limits for heavy metals and other elements, including barium, cadmium, chromium, lead, arsenic, mercury, selenium, and antimony. Additionally, it regulates vinyl chloride monomer content and specific phthalate esters (such as DBP, BBP, DEHP, DINP, DIDP, and DNOP). The standard also introduces limits for formaldehyde emission and Total Volatile Organic Compounds (TVOC) emission, transitioning from previous content limits to emission-based metrics using a climate chamber method. Compliance with these emission limits is critical for product safety. Finally, it restricts the use of short-chain chlorinated paraffins (C10-C13).

Métodos de ensayo

Testing involves specific methodologies for each regulated substance. Heavy metals are extracted and analyzed using atomic absorption spectrophotometry or ICP-MS/OES as per Appendix A. Vinyl chloride monomer is tested via gas chromatography according to GB/T 4615. Phthalates are measured per GB/T 37860. Formaldehyde and TVOC emissions are determined using the climate chamber method detailed in Appendix B, involving DNPH sampling tubes and gas chromatography. Short-chain chlorinated paraffins are tested according to GB/T 40263.

Preguntas frecuentes

What products are regulated under GB 18585-2023?

GB 18585-2023 regulates wallpapers of all base materials used in indoor decorating and refurbishing.

Are there any updates from the previous version of GB 18585?

Yes, compared to GB 18585-2001, this version adds limits for phthalates, TVOC emissions, and short-chain chlorinated paraffins. It also changes the formaldehyde metric to emission and updates testing methods for heavy metals.

How is formaldehyde tested under this standard?

Formaldehyde is tested as an emission using the climate chamber method described in Appendix B, rather than just a content limit.
