Introduction

GB/T 37188 is based on the findings of plastic users that when comparing the performance of similar materials, especially when the data sources are different, they cannot be used for similar materials.

Comparison of material properties. Even when the same standard test method is used, the data obtained is not sufficient due to the wide range of allowed test conditions.

Comparable. The purpose of this section is to identify specific methods and test conditions that can be obtained and represented as data so that materials can be

Make effective comparisons.

ISO 10350 is a standard for single-point data.The representation of this data is the most basic method for characterizing material properties.

Very useful. The current version specifies test conditions, test procedures, and more large-scale data representations. Multi-point data for each performance

Characterization, they show the relationship of this performance with many variables (such as time, temperature, environmental impact, etc.). This section also includes other

Some performance. This data helps determine whether the material is suitable for a particular application. Although some properties of the material are affected by its properties

The influence of the physical structure is great, and other data are needed from the design considerations, but some of the data obtained from this section can also be used to predict molding

Performance and optimal processing conditions. The tests in this section use multipurpose stretch splines wherever possible, but the polymer structure of the spline

It may still be significantly different from the specific area of the actual molded article. Therefore, in this case, the data obtained are not applicable to the performance of the product.

Accurate design calculations should be made with the material supplier for the applicability of the data required for special performance.

Each part of GB/T 37188 and ISO 10350 jointly determine the method of obtaining and representing a set of core comparable data used in material selection.

law. Adopting these standards can rationalize work while reducing the cost of obtaining data. In addition, reference to these standards can also help

Computer storage modeling of material performance data and data interchange.

This section appropriately specifies the variation of the test parameters, but for some tests, due to the corresponding test condition range for different plastic applications

It is very wide and gives guidelines for the selection of test conditions to ensure that the test conditions can cover the corresponding range when the polymer is applied. This

It is because in general, the properties and specific properties of different polymers are very different, so it is not necessary to update all the information in this section.

Data under test conditions.

In order to better select plastic materials and apply them to various applications, it is necessary to obtain their performance in a wide range.

The test procedures described in this section can help obtain some relevant information about various properties. GB/T 37188 is divided into several parts, each part

Points can be used independently. In order to develop new standards or revise this standard to include some other properties.

Obtaining and Representing Comparable Multipoint Data for Plastics

Part 1. Mechanical properties

1 Scope

This part of GB/T 37188 specifies test methods for obtaining and representing multi-point data on the mechanical properties of plastics.
