Even when using the same standard test method, due to the wide range of allowed test conditions, the obtained The data are also not comparable. The purpose of this standard is to identify specific methods and test conditions that can be used as data Effective comparison can be made between materials. ISO 10350 [4] [5] is a standard for single-point data.The representation of this data is the most basic method for characterizing materials. The primaries are very useful. The current version specifies test conditions, test procedures, and more large-scale data representations. Every performance has multiple points Data characterization, they show the relationship of this performance with many variables (such as time, temperature, environmental impact, etc.). This section also includes Some other properties. This data helps determine whether the material is suitable for a particular application. Although some properties of the material are affected by Its physical structure has a great impact, and other data are needed when considering design, but some data obtained by using this section can still be used for prediction. Performance and optimal processing conditions of the molded parts. The tests in this section use multipurpose stretch splines wherever possible, but the polymer of the spline The structure may still differ significantly from specific areas of the actual molded article. Therefore, in this case, the data obtained are not applicable to product properties. For accurate design calculations, the data applicability for special properties should be consulted with the material supplier. 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. But for some performance, there is no There are also significant shortcomings in establishing corresponding standards or this section, so it is difficult to obtain comparable data for these performances in accordance with this section (see appendix A). GB/T 37188 is divided into several parts, and each part can be used independently. In order to develop new or revised standards Can be included. Obtaining and Representing Comparable Multipoint Data for Plastics Part 3. Environmental impact on performance1 ScopeThis part of GB/T 37188 specifies test methods for obtaining and representing multi-point data on the mechanical properties of plastics. --- long-term thermal effects; --- Liquid chemicals; --- Stress cracking under constant tensile stress; --- Artificial aging. The tests are arranged according to the severity of the environmental conditions. The test is performed first in the lightest degree, and the result can be used as a judgement A reference for whether materials are worth testing in more demanding environments.2 Normative referencesThe following documents are essential for the application of this document.
