Scanning electron microscope method ICS 59.060.10 W21 National Standards of People's Republic of China Replacing GB/T 14593-1993 Cashmere, wool and mixed fibers quantitative Scanning electron microscopy analysis Posted 2008-08-20 2008-12-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard replaces GB/T 14593-1993 "cashmere, wool and mixed fibers quantitative analysis method." This standard and GB/T 14593-1993 compared to the main changes are as follows. --- Added "2 Normative references"; --- Altered the "density scales, scales the thickness" is defined in the relevant English expression (1993 version 2.4, 2.5; 3.2 edition, 3.3); --- Original standard "Method summary" to "principle", and modify the text description (1993 Edition Chapter 3; Chapter 4 of this edition); --- Modify the method of preparing the various states of the sample, and the sample is detected for the Preparation of fiber length of fiber subparagraph is amended 0.4mm; and added precautions (1993 Version 7.1 ~ 7.4 and 7.5; Excerpts of 8.1 to 8.4 and 8.3 Note); --- Modify the number of fibers need to measure the fineness, the original of each must be measured for each set of points to reduce fiber measuring 120 (1993 Edition 8.3; 9.3 edition); --- Modify the results formulation for the calculation of fiber content, increasing the diameter and standard deviation is calculated (1993 edition, Chapter 9; Excerpts Chapter 10); --- Test report will delete a fixed format (chapter 10 of the 1993 revision); --- Increase in the Appendix A describes the appearance of atypical cashmere morphological characteristics and the corresponding SEM image (Figure A.1 ~ Excerpts Figure A. 8), while increasing the SEM image other special animal fibers within the scope of this standard (Fig edition A.9 ~ Figure A. 14); --- Appendix B added fiber density data camel hair, mohair and yak and modify the data density cashmere (Excerpts Table B. 1). Appendix B of this standard is a normative appendix, Appendix A is an information appendix. This standard is proposed and managed by China Fiber Inspection Bureau. This standard drafting of the main unit. Fiber Inspection Bureau of Inner Mongolia, Inner Mongolia Erdos Cashmere Group Co., Ltd. The main drafters of this standard. Cao Wei Fang, Yanggui Fen, Qiu Ruiqing, Meng red, Hongxia, Wang Cuifang. This standard replaces the standards previously issued as follows. --- GB/T 14593-1993. Cashmere, wool and mixed fibers quantitative Scanning electron microscopy analysis1 ScopeThis standard specifies the use of a scanning electron microscope, the fiber content of various types of cashmere, wool and blended products were mixed with a given Method of quantitative analysis. This standard applies to cashmere, wool and mixed fiber and blended products. This standard also applies to the following types of fiber and blended Product. mohair, camel hair, angora and yak hair and the like.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. For undated reference documents, the latest versions apply to this standard. GB/T 8170 numerical rounding rules3 Terms and DefinitionsThe following terms and definitions apply to this standard. 3.1 There are regularly arranged on the sheet pile surface. 3.2 Per unit length along the fiber axis in the number of scales. 3.3 Height scale distal edge. Principle 4 Scanning electron microscopy of aggregated utilizing the electron beam has a certain energy scan the sample surface, secondary electrons excited to give Scanned image of the sample surface morphology. Scale structural features in accordance with cashmere, wool and other special animal fibers, such as flake form, scales Differences sheet density and thickness of the flake distinguish the various types of fiber, and were recorded and the number of the measured diameter, then calculate the amount of various types of fiber (Mass fraction,%).5 Reagents and materialsReagents and materials include. a) ethyl acetate (AR); b) double-sided adhesive tape; c) conductive plastic; d) gold. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 14593-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 14593-2008_English as soon as possible, and keep you informed of the progress.
