Basic dataStandard ID: GB/T 21865-2008 (GB/T21865-2008)Description (Translated English): Standard test methods for determining average grain size using semiautomatic and automatic image analysis Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: A80 Classification of International Standard: 13.300 Word Count Estimation: 28,249 Date of Issue: 2008-05-12 Date of Implementation: 2008-09-01 Adopted Standard: ASTM E1382-2004, IDT Regulation (derived from): Announcement of Newly Approved National Standards 2008 No. 8 (No. 121 overall) 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 defines the metallic and non-metallic polycrystalline material with an average grain size and grain size distribution intercept the basic measurement method. This standard applies to equiaxed grain structure type and extension -type single -phase and two-phase system specimens. This standard also applies to other similar crystal structure of the material, such as a cellular structure of the material. This standard requires the use of semi-automatic or fully automatic image analysis instruments. This standard only as a recommended test method, it can not determine whether to accept or by suitable test material scope of application. This standard does not consider all the relevant test security issues. Tests should be responsible for their own safety and health -related measures.

Full copy of true-PDF in English version (including equations, symbols, images, flow-chart, tables, and figures etc.) will be manually/carefully translated upon your order. Standard test methods for determining average grain size using semiautomatic and automatic image analysis ICS 13.300 A80 National Standards of People's Republic of China Measured by semi-automatic and automatic image analysis Standard Test Method Average particle size Posted 2008-05-12 2008-09-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard is equivalent to using the American Society for Testing and Materials standard ASTME1382. 04 "with semi-automatic and automatic image analysis in measuring the level Standard Test Method "average particle size (in English). The editorial changes made the following standard. --- Delete the original text of the preamble; --- Remove the original chapters directory section. Appendix A of this standard is a normative appendix; Appendix B is informative appendix. This standard is managed by the National Standardization Technical Committee chemicals dangerous (SAC/TC251) and focal points. This standard was drafted. China Inspection and Quarantine Science Research Institute, the Chemical Institute of Standardization, Guangdong CIQ. The main drafters of this standard. Falls Apart, Wang Lifeng, Wang Junbing at Wen Lin, Zhou Xin, Mei Jian, Chen Qiang. This standard is the first release. Measured by semi-automatic and automatic image analysis Standard Test Method Average particle size1 ScopeThis standard specifies the basic method of measuring the average grain size, and grain intercept area metal and nonmetal polycrystalline material distribution. This standard applies to single-phase and two-phase system and other specimen type axial elongation and grain structure. This standard also applies to other similar substance crystal structure, such as the material of the honeycomb structure. This standard requires the use of semi-automatic or fully automatic image analysis instruments. This standard is only recommended as a test method, it can not determine whether to accept or material that is suitable for testing the scope of application. This standard does not consider all trial-related security issues. Test measures should be responsible for their own safety and health-related.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents.
