Basic dataStandard ID: GB/T 32682-2016 (GB/T32682-2016)Description (Translated English): Plastics -- Determination of environment stress cracking (ESC) of polyethylene -- Full-notch creep test (FNCT) Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: G31 Classification of International Standard: 83.080.20 Word Count Estimation: 14,190 Date of Issue: 2016-06-14 Date of Implementation: 2017-01-01 Quoted Standard: ISO 2818 Adopted Standard: ISO 16770-2004, MOD Regulation (derived from): National Standard Announcement No. 8 of 2016 Issuing agency(ies): General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, Standardization Administration of the People's Republic of China Summary: This standard specifies test methods for the determination of the stress cracking resistance of polyethylene (PE) materials in environmental agents. In this test, a notched specimen is cut on a compression-molded test piece or article, and the specimen is immersed in an environmental agent, such as a surfactant solution, maintained at a predetermined temperature and subjected to a static tensile load to measure the breaking time. This standard applies to the evaluation of polyethylene materials, but also for the evaluation of hazardous materials/chemicals and other corrosive environments on polyethylene extrusion parts, such as pipe, polyethylene welding parts and polyethylene blow molding containers and other effects, other thermoplastic materials, Such as polypropylene (PP) can also refer to the use.

This standard uses the re-drafting method to modify the use of ISO 16770..2004 "plastic polyethylene environmental stress cracking (ESC) determination of the whole Gap creep test (FNCT) "(English version). This standard adds an appendix to the structure (Appendix B) compared to ISO 16770..2004. The technical differences between this standard and ISO 16770..2004 are as follows. --- increase the description, indicating that the distance between the fixture shown in the corresponding length of 100mm sample (see Figure 2), and the provisions of the standard Consistent - The reagents listed in this standard have been changed and the reagents listed in ISO 16770 are noted (see 6.1) to suit domestic reagents The actual situation; - the specific aging time of the reagent solution at the test temperature is removed and the aging time specified in ISO 16770 is taken as a note 6.1) to meet the use of different temperatures; - increased requirements for the use of non-overflow molds (see 7.2) to make the standard provisions more explicit; - the requirement to adjust the state of the specimen in the tropics (see 7.4) to comply with the actual distribution of the region in China; --- ISO 16770..2004 repeatability and reproducibility as informative Appendix B. This standard has made the following editorial changes. --- modified the gap position in Figure 3; --- Change the number of stress repeat specimens in Appendix B to 4.

Plastics - Determination of environmental stress cracking (ESC) of polyethylene Full Groove Creep Test (FNCT)1 ScopeThis standard specifies the test method for the determination of stress cracking resistance of polyethylene (PE) materials in environmental reagents. The test is in compression molding The sample or the product is cut with a notched specimen and the sample is immersed in an environmental reagent maintained at a prescribed temperature, such as a surfactant solution, State tensile load, determination of damage time. This standard applies to the evaluation of polyethylene materials, but also for the evaluation of hazardous materials such as hazardous materials/chemicals such as polyethylene extrusion Section, polyethylene frit and polyethylene blown containers, and other thermoplastic materials such as polypropylene (PP) can also be used. Note. The stress/orientation of the product during processing may have an effect on the results.2 normative reference documentsThe following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. ISO 2818 plastic machine preparation method (Plastics-preparedoftestspecimensbymachining)3 terms and definitionsThe following terms and definitions apply to this document. 3.1 Damage to failure The sample is completely separated from the two parts. Note. This section of the standard has been described in terms of broken sections, see 3.2 and 3.3. More information is available in the literature, see references. 3.2 Brittle fragmentation brittlefailure The cross-section shows permanent deformation of the material that is not visible to the naked eye, such as extension, elongation or necking, see Figure 1a). Note. Tensile ligaments may be formed at the center of the ductile material, see Figure 1b). a) brittle failure (no deformation) b) brittle failure (center forming tensile ligament) c) ductile failure Figure 1 broken section ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 32682-2016_English be delivered?Answer: Upon your order, we will start to translate GB/T 32682-2016_English as soon as possible, and keep you informed of the progress.
