What types of flaw detection methods are these?

As shown in the figure above, what inspection methods do ET, UTA, UTS, and AE correspond to, and for what materials are they used? Thank you.
ET stands for eddy current testing； UTA refers to online ultrasonic flaw detection ； AE stands for acoustic emission testing.

The screenshot posted by the original poster must be related to some standard – what is the standard number?
Eddy current testing is mainly used for what types of materials? Is it stainless steel? Is acoustic emission what they call TOFD?
I think we can take a look at NB/T 47013.1-2015 Non-destructive testing of pressure equipment – Part 1: General requirements

The attachment is the complete set of NBT47013; compared to the dozen-plus attachments mentioned in several posts on the forum, this single attachment makes it more practical for people to download. Haha
ET is eddy current testing, MT is magnetic particle testing, PT is penetrant testing, RT is radiographic testing, and AE is acoustic emission. Magnetic powder is preferentially used for the surfaces of ferromagnetic materials, while penetrant testing is used for stainless steel surfaces. Eddy current testing is generally applicable to the inspection of heat exchange tubes or air-cooled tube banks.
