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, impact resistance to falling balls, color fastness to light, resistance to cigarette burning, stain resistance, resistance to dry heat, resistance to heat and humidity, and resistance to cold

Hot water circulation, hardness, repairability 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.

Decorative solid surface material for plastic products

Part 3.Determination of performance of non-plate solid surface materials

1 Scope

This document describes the test methods for various properties of non-plate solid surface materials.

This document applies to materials specified in GB/T 40426.1.

These methods can be used to test non-plate solid surface products, but the test is generally carried out on a flat plate whose size meets the test requirements; the measured

The tested flat material and surface treatment should be the same as the non-plate solid surface material.
