Foreword

This standard is identical with ISO /ASTM51649.2005 "energy of 300keV ~ 25MeV electron beam radiation processing dosimetry Guidelines "(in English). For ease of use, this standard made the following editorial changes. a) prepared in accordance with Chinese customary for some format has been modified. b) for ISO /ASTM51649. other international standards cited in 2005 have been adopted as the equivalent of the standard, this section with References of these national standards or industry standards corresponding to international standards in place, the rest not equivalent to the standards of China International standards in this standard are a direct reference. c) the original number of international standards in Appendix A1, A2, A3, A4 to Appendix A, Appendix B, Appendix C, Appendix D. This standard replaces GB/T 16841-1997 "energy of 300keV ~ 25MeV electron beam radiation processing dosimetry guidelines." this Standard and GB/T 16841-1997 main changes are as follows. --- Redefined the standards applicable to the "scope" (1997 version of Chapter 1; Chapter 2 of this edition); --- An increase of some terminology, and the original part of the standard terminology redefined (Excerpts Chapter 3); --- Added "dosimeter calibration system" article and specific requirements (see Excerpts 7.3.1,7.3.2,7.3.3, Note 4); --- With "Confirm Installation", "Operation Qualification", "performance verification" and "daily production process," replaced "means to confirm," "confirmation process" and "Daily production and processing" (see the 1997 version of Chapter 7, Chapter 8, Chapter 9; edition, Chapter 9, Chapter 10, Chapter 11, Section 12 chapter); --- Added "Processing Parameters" chapter content (see Chapter 8 edition); --- Increasing the uncertainty of classification standards and evaluation criteria (see Chapter 13); --- Refine the initial energy of the electron beam is determined by the depth dose distribution methods methods and conditions (see Appendix A Excerpts); --- Re-described "microwave power accelerator" and "RF Power Accelerator" performance characteristics (see Appendix D of this edition and D.1.2 D. 1.3).
