Foreword
This specification is drafted in accordance with the rules given in GB/T 1.1-2009.
This specification replaces GB/T 12078-1989 "X-ray tube general specification".
The main changes in this specification compared with GB/T 12078-1989 are as follows.
- the use of GB/T 10149 "medical X-ray equipment terminology and symbols" and GB/T 4597 "tube vocabulary" in the relevant terms;
--- photoelectric performance indicators to increase the leakage current, remove the X-ray tube anode current stability, gate control X-ray tube filament gate
Pressure
- a test method that specifies the durability of work;
--- reference GB/T 2828.1-2003 instead of the original count check sampling program.
This specification is proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
The specification by the National Electrical Vacuum Device Standardization Technical Committee (SAC/TC167) centralized.
The drafting unit. Hangzhou Wandong Electronics Co., Ltd.
The main drafters of this specification. Hu Haihong, Tian Feng, Fu Yongmin, Yu Xiaomei, Hu Youcheng.
This specification is replaced by previous versions of the standard release.
--- GB/T 12078-1989.
