Foreword

This corresponds to the standard IEC 60476.1993 "Nuclear instruments utilizing ionizing radiation sources of electrical measuring instruments and systems General characteristics", and IEC 60476.1993 non-equivalent. This standard replaces GB/T 7352-1987 "electrical measuring instruments utilizing radioactive sources." This standard and GB/T 7352-1987 the main differences are as follows. --- Standard name changed to "the use of ionizing radiation sources of electrical measuring instruments and systems"; --- Update and add normative references (see Chapter 2); --- According to IEC 60476 adds terms and definitions (see Chapter 3); --- Increasing the electromagnetic compatibility requirements (see 4.1.4.4); --- Added "Inspection Rules" chapter of the factory inspection and type inspection made in principle provides for the development of specific standard products mention For a basis (see Chapter 6); --- Added "signs, packaging, transport and storage" chapter, so that standard of structural integrity (see Chapter 7); --- Delete the original standard in Appendices A and B; --- Appendix A was placed IEC 60476.1993 Section 4.2 features. Appendix A of this standard is an informative annex. 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. Shanghai Industrial Automation Instrument Research Institute, Institute of Nuclear Industry Standardization, Shenzhen Academy of Metrology and Quality Inspection. The main drafters of this standard. Li Jiajia, Xiongzheng Long, Zhou Yingchun, Tsai Wen-chi, XU Xiao Wei, Li name trillion. This standard replaces the standards previously issued as follows. --- GB/T 7352-1987. The use of sources of ionizing radiation measuring electrical systems and instrumentation

1 Scope

This standard specifies the use of ionizing radiation sources electrical measuring instruments and systems terminology, technical requirements, test methods, inspection rules, and standard Chi, packaging, transport and storage. This standard applies to the use of ionizing radiation of electrical measuring instruments and systems, it can provide a basis for the development of the relevant product standard, but also as a system Factory made between the user guide and signed the agreement.
