GB/T 35513.2-2017Plastics -- Polycarbonate (PC) moulding and extrusion materials -- Part 2: Preparation of test specimens and determination of properties (English PDF)

Foreword

GB/T 35513 "plastic polycarbonate (PC) molding and extrusion material" is divided into two parts.

--- Part 1. Naming system and classification basis;

--- Part 2. Preparation of samples and performance testing.

This section GB/T 35513 Part 2.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section uses the redrafted law revision using ISO 7391-2:2006 "plastic polycarbonate (PC) molding and extrusion materials 2 Part. Sample preparation and performance testing "(in English).

This part of ISO 7391-2:2006 technical differences and the reasons are as follows.

--- On the normative references, this section made a technical difference with the adjustment to adapt to China's technical conditions, adjust the situation Concentration reflected in the second chapter "Normative references", the specific adjustments are as follows.

- Equivalent to the use of international standards GB/T 1034-2008 instead of ISO 62:1999;

- Replaced IEC 60250:1969 with revision GB/T 1409-2006 of international standard;

- Replace ISO 306:2004 with GB/T 1633-2000 equivalent to international standards;

- Replaced IEC 60296:2003 with GB 2536-2011 modified to adopt international standards;

- Equivalent to the international standard GB/T 2918 instead of ISO 291:2005;

- Equivalent to the use of international standards GB/T 4207-2012 replaced IEC 60112:2003;

- Equivalent to the international standard GB/T 19467.1 instead of ISO 10350-1:1998;

- ISO 7391-1 deleted.

--- Mechanical testing of the state when the time from "4h" to "24h." this section made the following editorial changes.

--- Adjust the order of the table will be ISO 7391-2:2006 Table 1 to Table 3 of this section, ISO 7391-2:2006 Table 2 to

Table 4 of this part, Table 3 of ISO 7391-2:2006 is replaced by Table 1 of this part, Table 4 of ISO 7391-2:2006 is replaced by Part

Table 2

--- Chapter 2 and Chapter 3 ISO 7391-2:2006 merged into Chapter 2 of this section, and in turn modify the other chapter serial number.

This part is proposed by China Petroleum and Chemical Industry Federation.

This part of the National Plastics Standardization Technical Committee Engineering Plastics Sub-Technical Committee (SAC/TC15/SC9) centralized.

This part of the drafting unit. China Blue Star (Group) Co., Ltd., Blue Chenguang Chengdu Testing Technology Co., Ltd., Wuhan Golden Technology Co., Ltd., Guangzhou Poly-Long Engineering Plastics Co., Ltd., Luxi Group Co., Ltd., Mid-Blue Chenguang Chemical Research and Design Institute Co., Ltd.

1 Scope

This section GB/T 35513 specifies the preparation of polycarbonate molding and extrusion materials for the performance of the sample preparation process and test side law. This section specifies the method of treatment of the material being tested as well as the state of the test material before the test and the test sample conditioning requirements.

This section gives the polycarbonate molding and extrusion sample preparation process and conditions and the use of these samples to test the performance of the material Method, but also lists the properties required to characterize polycarbonate molding and extrusion materials and how they are tested.

Performance project is selected from the general test method GB/T 19467.1. Some of the other particulars of polycarbonate molding and extrusion materials are of particular importance or Widely used test methods are also included in this part of GB/T 35513, the characteristic performance can be found in GB/T 35513.1.

In order to obtain comparable and reproducible test results, should be in accordance with the provisions of this part of the sample preparation process and state adjustment method, the test Sample size and test method. Test data using different sample sizes or sample preparation methods may not always agree.
