There are technical differences between this document and ISO 19712-1.2008.The relevant differences have been incorporated into the main text and

The margin of the paragraph is marked with a single vertical line (|). A list of these technical differences and their reasons is given in Appendix B.

Introduction

This document is intended for use by manufacturers of decorative solid surface materials, assemblers, construction parties and design units.

The proposed test method and its performance requirements are closely related to the use of the product. The installation method and process may affect the performance of the product.

Health impact.

Performance requirements include but are not limited to color and finish, size, appearance quality, resistance to dry heat, resistance to moisture and heat, resistance to falling ball impact, and anti-fouling

Resistance, color fastness to light, resistance to cigarette burning, resistance to cold and hot water cycles, load testing and other important properties.

GB/T 40426 consists of three parts.

---Part 1.Classification and specification. The purpose is to specify the performance requirements of decorative solid surface materials

---Part 2.Determination of performance of plate-shaped solid surface materials. The purpose is to specify the test method for plate type solid surface materials

---Part 3.Determination of performance of non-plate solid surface materials. The purpose is to specify the test method for non-plate solid surface materials.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1

Solid surfacing material; SSM

Composed of polymer materials, fillers and pigments, plate-shaped products or non-plate-shaped products formed by processes such as pouring or pressing.

Note 1.The solid surface material is made of the same material.

Note 2.The surface of the artificial marble surface material is repairable.

Note 3.The solid surface material can realize seamless splicing.

3.2

Artificialmarblestonesurfacingmaterial

Take polymethyl methacrylate (PMMA) or unsaturated polyester resin (UPR) as the matrix, mainly use aluminum hydroxide as the filler, and add pigment

Materials and other auxiliary agents, solid surface materials such as casting molding or vacuum molding or compression molding.

3.3

Artificial quartz stone surfacing material

Natural quartz stone (sand, powder), silica sand, tailings slag and other inorganic materials (the main component of which is silica) are used as the main raw materials.

Polymer is a solid surface material made of adhesive material.
