Foreword
This standard is identical with ISO /ASTM51707.2005 (E) "dose radiation processing Uncertainty Evaluation Guidelines" (in English).
For ease of use, this standard made the following editorial changes.
a) according to the Chinese custom for some formatting has been modified.
b) for ISO /ASTM51707. other international standards cited in 2005 have been adopted as the equivalent of a standard, this standard with
References of these national standards or industry standards corresponding to international standards in place, the rest not tantamount to the adoption of the standards of China
International standards in this standard are a direct reference.
c) the original number of international standards Appendix A1, A2, A3, A4, A5 to A, B, C, D, E.
This standard replaces GB/T 16509-1996 "dose radiation processing of Measurement Uncertainty Guide." This standard and GB/T 16509-
The main changes compared to 1996 are as follows.
--- Adjust some terms and definitions (see Chapter 3, 1996 edition; the first edition chapter 3);
--- Redefined the standard "meaning and purpose" (1996 version 4.1; this edition 4.1,4.2,4.3,4.4,4.5);
--- Increase the role of uncertainty components based on the classification and classification (see 6.1.1.1,6.1.1.2,6.1.1.3,6.1.1.4) ;
--- Increasing the uncertainty of A Class Evaluation Example (see this edition 6.2.4);
--- Increasing the provision and analysis of dosimeter measurement system calibration (see section 7.3 and 7.4 of this edition);
--- Increasing the different calibration methods of uncertainty analysis (see this edition 7.5,7.6,7.7);
--- Increased uncertainty components assessment purposes (see this edition 9.3);
--- Adjust the entire contents of the appendix (see 1996 edition A; Excerpts Appendix A, B, C, D, E);
--- Remove the 1996 version of Appendix B "Bibliography", add "References."
The Standard Appendix A, Appendix B, Appendix C, Appendix D and Appendix E is an informative annex.
