Foreword
This standard is GB/T 4078-1991 "liquid scintillation counting bottle size", GB/T 4080-1983 "radiation measurement
Tube size "and GB/T 8996-1988" sample tray size "consolidated amendments nuclear electronic instruments.
This standard and GB/T 4078-1991, GB/T 4080-1983 and GB/T 8996-1988 compared to the main changes are as follows.
The standard Chapter 3, "Nuclear Instrument sample pan and Size" (formerly GB/T 8996-1988) adopted IEC 60248. 1984 sample tray
Size, minor modifications and additions include.
1) In the well-type sample tray size, the increase in the diameter of 21mm profile, increase the height of 2mm profile;
2) The well-type sample disc diameter 77mm ~ 200mm tolerance by the "0-0.2" to "
-0.3
";
3) diameter is greater than 60mm, a height greater than or equal to 2mm, the maximum wall thickness changed from 0.6mm "0.8mm";
4) "on the surface flatness error should not exceed 0.1mm" to "any flatness errors on the surface of 20mm diameter circular area
The range should not exceed 0.1mm ";
5) In this standard the well type, flat type and size of dish sample tray, in exceptional cases does not preclude the use of other size or shape
Like sample tray.
