What is the standard of X-ray nondestructive testing?

It seems that there is no separate X-ray flaw detection standard, only X-ray flaw detection standard, including gamma rays. At present, the commonly used standards are JB/T4730 standard and GB3323 standard, so it depends on which industry you are in, and ASME standard and EU standard are also implemented in the production and export products.

The standard upstairs is the manufacturing standard of flaw detector, not the flaw detection standard.
