Introduction

The reason for developing the GB/T 19467 series of standards is that plastic users found that existing data was sometimes unusable for comparing the performance of similar materials.

This is especially true when the data comes from different sources. Even when using the same testing method, the wider range of experimental conditions allowed by the method makes a difference.

The data obtained are also not comparable. GB/T 19467 aims to specify specific test methods and conditions for the effective comparison between materials.

The acquisition and representation of the required data.

The GB/T 19467 series of standards lists the test methods used to represent single-point data within a certain range. These test methods are for data...

The report typically includes the pre-selected material properties. These data are the most fundamental methods for describing material properties, therefore...

The development of the GB/T 19467 series of standards marked the first step towards more effective selection and use of materials suitable for the many applications of plastics.

Following the release of the GB/T 19467 series of standards, a series of national standards, GB/T 37188.1, were also released, focusing on the acquisition and representation of multi-point data.

GB/T 37188.2 and GB/T 37188.3 are used to demonstrate the influence of important factors such as time, temperature, and specific natural and chemical environments on performance.

The GB/T 37188 series of standards also includes some additional performance characteristics. The use of these standards will provide a more comprehensive set of data than simply containing single-point data.

A more comprehensive database allows for improved assessment of the suitability of materials for any specific application. Additionally, GB/T 37188.1 this relates to mechanical properties, which helps in predicting the mechanical properties of materials. GB/T 37188.2 relates to thermal and processability properties, which helps in predicting the mechanical properties of materials.

Flow properties during processing. GB/T 37188.3 focuses on the impact of the environment on performance; other parts of the standard may be developed to cover this.

Increase performance.

GB/T 19467 "Obtaining and Representing Comparable Single-Point Data for Plastics" is proposed to consist of two parts.

---Part 1: Molding Materials. The purpose is to determine the molding materials typically used in the pre-selected materials, expressed in terms of single-point data.

The performance characteristics and the experimental methods used to obtain these single-point data.

---Part 2: Long Fiber Reinforced Materials. The aim is to determine the common use of long fiber reinforced materials in the pre-selected materials, using single-point...

The various performance characteristics of the data representation and the experimental methods used to obtain this single-point data.

Obtaining and representing comparable single-point data for plastics Part 1: Molding Materials

1 Scope

This document specifies the test procedures for comparing the basic properties of plastic molding materials, for the acquisition and representation of comparable data.

Note 1.Usually each performance is determined by a single test value, although in some cases, different test conditions may yield different test values for the same performance.

Note 2.The performance listed in this document is the performance that is usually found on the data sheets provided by the manufacturer.

This document applies to unreinforced and reinforced thermoplastics and thermosetting plastics that can be injection molded, compression molded, or prepared into specimens of specified thickness.

plastic.

This document does not apply to discontinuous or continuous fiber reinforced thermoplastics and thermosetting plastics with a fiber length exceeding 7.5 mm before molding.

Plastics.

Note 3.GB/T 19467.2 is specifically for long fiber or continuous fiber reinforced plastics.
