Introduction

This section is intended for 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, appearance quality, resistance to dry heat, resistance to humidity, falling ball impact, stain resistance, and light resistance Color fastness, cigarette burning resistance, resistance to cold and hot water circulation, load test, 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 2.Determination of performance of plate-type solid surface materials

1 Scope

This document describes the test methods for each performance of plate-type solid surface materials. This document applies to materials specified in GB/T 40426.1. These methods can be used to test plate-shaped solid surface products, but the test is generally carried out on a flat plate whose size meets the test requirements; the tested The flat plate material and surface treatment are the same as the plate-shaped solid surface material.
