GB/T 13980-2008Density gauges utilizing ionizing radiation (English PDF)

Foreword

This standard corresponds to IEC 60692:1999 "densitometer definitions and test methods for the use of ionizing radiation", and IEC 60692:1999 Non-equivalent.

This standard replaces GB/T 13980-1992 "ionizing radiation densitometer." the main difference compared with the standard GB/T 13980-1992 as follows.

--- Normative references, the latest version of the standard references appropriate;

--- Terms and definitions, according to IEC 60692:1999 "definition" of the preparation, and consistent with GB/T 7352;

---skills requirement.

- adjust the technical requirements of the order of items, according to the appearance, the basic performance requirements of the order and working atmosphere Conditions and power supply conditions and their impact on performance density meter separate statements (Chapter 5);

- adjust and supplement some indicators technical requirements (Chapter 5);

- atmospheric conditions and working conditions of the power supply according to IEC 60692:1999 Annex A are divided into I, II, III three groups 1, 2 and three levels (5.1.2);

- Increase AC power supply frequency, electromagnetic environmental conditions, resistance to vibration, shock and other environmental suitability of packaging and transportation requirements;

- Safety requirements (including electrical and radiation safety) and the test methods according to GB/T 19661-2005 prepare and give Specific parameters (5.7);

- Increase the diagnostic features and reliability requirements (5.8,5.9);

---experiment method.

- supplementary part of the test methods, such as electromagnetic environmental testing, and other sources to make it correspond with the technical requirements;

- rewrite part of the test methods, mostly according to IEC 60692:1999 The "test" to prepare, but the climate and environmental testing machine Environment Press GB/T 8993-1998 prepared while electromagnetic environment according to GB/T 11684-2003 write;

--- Inspection rules, supplementary classification test, refine the test item list (Chapter 7);

--- Additions accompanying document (Chapter 8);

--- Increase in Appendix A (Informative Appendix), IEC 60692 standard is not used to this. Test methods for 1999 included in Appendix A.

Appendix A of this standard is the data appendix.

The standard proposed by China National Nuclear Corporation.

This standard by the National Nuclear Instrument Standardization Technical Committee (SAC/TC30) centralized.

This standard was drafted. Shenzhen Academy of Metrology and Quality Inspection, Shanghai Industrial Automation Instrument Research Institute, Institute of Nuclear Industry Standardization.

1 Scope

This standard specifies the ionizing radiation densitometer product classification, technical requirements, test methods, inspection rules and signs, packaging, transportation, storage Memory and accompanying documents.

This standard applies to the use of ionizing radiation the average density of matter measuring ionizing radiation densitometer (hereinafter referred densitometer).
