Chemical composition analysis method for resin-based artificial stone

1 Scope

GB/T 47191-2026 is the Chinese national standard covering the composition of engineered stone - the resin fraction, the quartz or marble filler and the pigments, which determine both the performance of the material and, in the case of the crystalline silica, the hazard to the people who cut it. First edition, in force since 1 September 2026. It was issued on 27 February 2026 and has been in force since 1 September 2026, as a first edition. The document is under the responsibility of the China Building Materials Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document describes the qualitative and quantitative analysis methods for the chemical components in resin-based artificial stone. This document applies to resin-based artificial quartz stone, resin-based artificial solid surface materials, and resin-based artificial engineered stone containing resin, aluminum hydroxide, and carbonate. Qualitative and quantitative analysis of the chemical composition of salt, quartz and silica.
