Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part

1.Structure and drafting rules for standardization documents" Drafting. This document replaces GB/T 35610-2017 "Green Product Evaluation of Ceramic Tiles (Boards)". In addition to structural adjustments and editorial changes, the main technical changes are as follows:

a) The scope has been changed (see Chapter 1, Chapter 1 of the.2017 edition);

b) Deleted the terms and definitions of "unit product comprehensive energy consumption", "environmental product declaration" and "carbon footprint" (see 3.1,.2017 version) 3.2, 3.3);

c) The method of "product classification" has been deleted (see Chapter 4 of the.2017 edition);

d) Changed the requirements for "Product Packaging" (see 4.1.1.1, Table 1 of the.2017 edition);

e) The requirement for "Green Supply Chain Management" has been deleted (see

5.1.1.1 of the.2017 edition);

f) Changed the requirements for "clean energy" (see 4.1.1.2,

5.1.1.2 of the.2017 edition);

g) Changed the requirements for "advanced technology and process" (see 4.1.1.2,

5.1.1.2 of the.2017 edition);

h) The requirements for "basic performance of products" have been changed (see 4.1.2,

5.1.2 of the.2017 edition);

1 Scope

GB/T 35610-2024 is the Chinese green product assessment standard for ceramic tiles and boards. Tile is fired at high temperature in enormous volume, which makes it one of the most energy intensive building products in use, and the industry has moved toward thinner and larger formats precisely because they cut the material and the firing energy per square metre. The standard sets the basic requirements a product must satisfy before assessment, covering compliance, pollutant discharge and energy consumption, and then the evaluation indicators grouped as resource attributes including the thickness and mass per unit area and the use of industrial solid waste in the body, energy attributes covering the firing and drying energy, environmental attributes covering the emissions, the wastewater and the recycling of process waste, and quality attributes covering the water absorption, strength, wear and slip resistance and the radioactivity of the finished tile, each with its limit and its verification method, together with the evaluation method and the rules for a claim. It takes effect on 1 May 2025.

This document specifies the evaluation requirements and methods for green products of ceramic tiles (boards). This document applies to the green product evaluation of ceramic tiles (boards).
