Introduction

GB/T 6594 is the basic standard for polystyrene resin and provides support for polystyrene product standards. ISO 1622, due to changes in the ISO standard guidelines, the naming system has been adjusted accordingly, closely related to sample preparation and performance determination. The relevant test method standard has been revised and there are technical differences, so GB/T 6594 is revised. GB/T 6594 "Plastic Polystyrene (PS) Molding and Extrusion Materials" consists of two parts. --- Part 1.Naming system and classification basis. The purpose is to establish a standard model for the naming of polystyrene materials Methods and classification principles. --- Part 2.Sample preparation and performance determination. The purpose is to establish the sample preparation method and performance test for polystyrene materials Measurement items, methods and conditions. This document specifies uniform specimen preparation, state adjustment, and specimen size based on the characteristics of polystyrene (PS) molding and extrusion materials. and test conditions to obtain reproducible and comparable test results, which provides support for polystyrene product standards. Plastic polystyrene (PS) molding and extrusion materials Part 2.Preparation of test specimens and determination of properties

1 Scope

This document describes methods for the preparation of test specimens and the determination of properties of polystyrene (PS) molding and extrusion materials. Requirements for pretreatment of test materials and condition adjustment of test specimens before testing. This document specifies the methods and conditions for the preparation of test specimens and the determination of properties. Suitable and necessary properties of materials and test methods. These properties are selected from the general test methods of GB/T 19467.1.This document also lists the properties of polystyrene (PS) molding and extrusion Other test methods that are widely used or have special significance for materials, as well as the determination methods of the named properties in GB/T 6594.1.
