T/CSTE 0076-2021 "Leader standard evaluation requirements for artificial stone"

Scope

Scope: This document specifies the terms and definitions, evaluation index system, and evaluation methods for the "Leader" standard evaluation of artificial stone. This document is applicable to the evaluation of enterprise standard levels of artificial stone solid panels, artificial stone quartz stone, and artificial stone granite products used in countertops, walls, floors, ceiling materials, decorative panels, and board lines. Relevant institutions may refer to this document when formulating "Leader" evaluation schemes for enterprise standards, and enterprises may also refer to it when formulating their own enterprise standards. Main technical content: 4.2.1 The evaluation indices of the "Leader" standard for artificial stone include basic indices, core indices, and innovative indices. 4.2.2 Basic indices include dimensional deviation, appearance quality, linear expansion coefficient, load deformation and toughness, water absorption, chemical resistance, heat resistance, high-temperature resistance, flame resistance, glossiness, radioactive protection classification control, and requirements related to Barth hardness. 4.2.3 Core indices include flexural strength, compression strength, Mohs hardness, ball drop impact resistance, abrasion resistance, color fastness and aging performance, and anti-pollution performance. 4.2.4 Core indices are divided into three levels: advanced, average, and baseline. The advanced level corresponds to the 5-star level in the enterprise standard ranking list; the average level corresponds to the 4-star level in the enterprise standard ranking list; and the baseline level corresponds to the 3-star level in the enterprise standard ranking list. 4.2.5 Innovative indices include heavy metal content and scratch resistance. It is encouraged to add innovative indices related to product performance and consumer concerns when conditions permit.
