Plastics--Acquisition and presentation of comparable multipoint data--Part 2. Thermal and processing properties ICS 83.080.01 G31 National Standards of People's Republic of China Plastics are comparable to the acquisition and representation of multipoint data Part 2. Thermal properties and processability Part 2. Thermalandprocessingproperties (ISO 11403-2.2012, IDT) Published on.2018-12-28 2019-11-01 implementation State market supervision and administration China National Standardization Administration issued ForewordGB/T 37188 "Plastic and comparable multipoint data acquisition and representation" is divided into the following three parts. ---Part 1. Mechanical properties; --- Part 2. Thermal properties and processing properties; --- Part 3. The impact of the environment on performance. This part is the second part of GB/T 37188. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This section uses the translation method equivalent to ISO 11403-2.2012 "Plastic comparable multipoint data acquisition and representation Part 2. Hot Performance and processability. The documents of our country that have a consistent correspondence with the normatively cited international documents in this section are listed in Appendix NA. This standard has made the following editorial changes. --- Added informative Appendix NA. This part was proposed by the China Petroleum and Chemical Industry Federation. This part is under the jurisdiction of the National Plastics Standardization Technical Committee (SAC/TC15). This standard is drafted by. China Petroleum and Chemical Corporation Beijing Yanshan Branch Resin Application Research Institute, Zhonglan Chenguang Chengdu Testing Technology Co., Ltd., Tongdao Technology Chengdu Co., Ltd., Shandong Daun Polymer Materials Co., Ltd., Chemical Research of Chinese Academy of Sciences , Zhonglan Chenguang Chemical Co., Ltd.

Can compare. Even when the same standard test method is used, the data obtained is not comparable because of the wide range of test conditions allowed. Sex. The purpose of this section is to determine the specific methods and test conditions that can be obtained and represented as data, so that Comparison of effectiveness. 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 representations of more large amounts of data. 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. These data help to determine whether a material is suitable for a particular application. Some data can also be used to predict molding The performance of the piece and the best processing conditions, although other data are needed from the design considerations, one of the reasons is the materiality Can be greatly affected by its physical structure. The test in this section uses a multi-purpose tensile spline as much as possible, but the condensed state of the spline The structure may be significantly different from the specific area of the actual molded article. Therefore, in this case, the data obtained does not apply to product performance. Accurate design calculations, data suitability for specific performance should be consulted with the material supplier. The various parts of GB/T 37188 and ISO 10350 together determine the acquisition and presentation of a set of core comparable data used in the selection of materials. law. Using these standards can rationalize work while reducing the cost of acquiring data. In addition, reference to these standards also helps to simplify the material Computer storage modeling and data interchange of material performance data. This section appropriately specifies the variation of the test parameters, but for some tests, the range of test conditions corresponding to different plastic applications It is very broad and gives guidelines for the selection of test conditions to ensure that the test conditions cover the corresponding range of polymer applications. This Because in general, the properties and specific properties of different polymers are very different, so there is no need to update this section one by one. The data under the test conditions of the column. In order to better materialize the plastic and apply it to a variety of applications, it is necessary to obtain a wide range of properties. The experimental steps described in this section can help you get some relevant information about each performance. But as far as some performance is concerned, there is currently no There are also significant deficiencies in establishing the corresponding standards or in this section, so it is difficult to obtain comparable data for these properties in accordance with this section (see appendix A). This standard is divided into several parts, each part can be independently formed into chapters. In this way, when developing new standards or revisions of this standard, other properties can be To include it. Plastics are comparable to the acquisition and representation of multipoint data Part 2. Thermal properties and processability1 ScopeThis part of GB/T 37188 describes the test steps for obtaining and representing multi-point data for the following thermal and processing properties of plastics. ---Hot 焓-temperature curve; ---Linear expansion-temperature curve; --- Melt shear viscosity - shear strain rate curve.2 Normative referencesThe following documents are indispensable for the application of this document.
