Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard uses the redrafted law to amend the use of IEC 62495..2011 "nuclear instrumentation portable tube excitation X-ray fluorescence analyzer."
This standard IEC 62495..2011 technical differences and the reasons are as follows.
--- On normative references, this standard 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.
● Replacing IEC 60982. 1989 with GB/T 11923 that does not equivalently adopt international standards;
● Replace IEC 60692..1999 with GB/T 13980, which is not equivalent to international standards;
● Replacing IEC 61336..1996 with GB/T 15636 that is not equivalent to international standards;
● IEC 61326 (all parts) replaced by GB/T 18268 (all parts) that is not equivalent to international standards;
● increase the reference GB 18871-2002;
● increase the reference GB/T 31364-2015.
--- Chapter 3, "Terms and definitions", according to the standard using the circumstances were cut and the order of adjustments; delete the "collimation device" "Probing
Box "" Circuit measurement device "" Handheld device "" Measuring head "under" normal conditions "" portable device "" radiation generating device "" Department
System Shield "" alarm device "" X-ray fluorescence measurement system "a total of 11 terms;
--- Added 5.5.2.3 "distance sensor", the two types of sensors described in 5.5.2.2.2 and 5.5.2.2.3 as "distance sensor";
--- 7.2 Added 7.2.1,7.2.2,7.2.3,7.2.4, a clear electromagnetic compatibility test technical requirements and test methods.
This standard made the following editorial changes.
--- In line with the existing standard series, the standard name changed to "portable tube excitation X-ray fluorescence analyzer classification, safety
Seeking its test ";
--- Added "Introduction", IEC 62495..2011 in Chapter 1 of the standard preparation purposes and the "portable tube excited X-ray fluorescence
Optical analyzer "profile into the" Introduction ";
--- Chapter 1 "Range" According to GB/T 1.1-2009 requirements, an increase of "This standard specifies the portable tube excitation X-ray fluorescence analysis
Terms and definitions of instruments, classification, safety requirements and tests, and warning labels and instructions. ";
--- Chapter 6 "Warning signs and instructions" According to our standard habits, will be marked that a unified representation;
--- Added Table A.1, Appendix A of the ambient temperature and relative humidity and other parameters are placed in Table A.1;
--- Reference lists an increase of the reference to the relevant national standards and industry standards of our country.
This standard proposed by China National Nuclear Corporation.
This standard by the National Nuclear Instrument Standardization Technical Committee (SAC/TC30) centralized.
This standard was drafted. Institute of High Energy Physics, Chinese Academy of Sciences.
The main drafters of this standard. Wei Long, Zhao Jingwei, Xiong Zhenglong, Feng Minzi, Guo Jing, Li Zhuoxin.
Introduction
This standard is intended for portable tube excitation X-ray fluorescence analyzer (hereinafter referred to as portable XRF analyzer) and radiological safety related
Design and operation of, and experimentation with, performance specifications for common radiation, electrical, safety and environmental characteristics to minimize and avoid
Health risks during use. Portable XRF analyzer general performance and test methods see GB/T 31364-2015.
Portable fluorescence analyzers using low-power, small x-ray tubes as ionizing radiation sources represent a new type of industrial equipment. use
Portable analyzers with small X-ray tubes to replace radioisotope sources (eg, 55Fe, 57Co, 109Cd, 241Am and 244Cm) have been used
Such as the analysis of lead in paint, alloy identification, screening of soil containing harmful substances.
