Scope

This Part of GB/T 37910 specifies acceptance levels for indications from imperfections
in butt welds of steel, nickel, titanium and their alloys detected by radiographic testing.
If agreed, the acceptance levels can be applied to other types of welds or materials.
The acceptance levels can be related to welding standards, application standards,
specifications or codes. This Part assumes that the radiographic testing has been
carried out in accordance with GB/T 3323.1 or GB/T 3323.2. When assessing whether
a weld meets the requirements specified for a weld quality level, the sizes of
imperfections permitted by standards are compared with the dimensions of indications
revealed by a radiograph made of the weld.
