B31.3 2016 Chapter IX - high pressure - DPI MPI accpetance criteria

Is someone is aware of a code case which state the acceptance criteria to be used for chapter IX for DPI and MPI?
My understanding based on K341.3.2 & K341.5 is acceptance criteria for VT described in table K341.3.2 to be used for surface NDT.
This approach is similar to AWSD1.1 and to have have white PT at such pressure is understandable.
The better answer would be an code case to prove my understanding.

There will be no changes to the sections you have noted in the 2020 edition of B31.3 so there are no code cases applicable.

Research Center IDEKO develops an ultrasonic train wheel inspection system for CAF

The Basque Research centre IK4-IDEKO has developed a state-of-the-art ultrasonic inspection system f
or the train wheel. This system secures a sound condition of train wheels and is thus a significant contribution to rail transport safety. The device was delivered to CAF recently and its use allows the manufacturer to become an approved supplier of rolling stock in Italy, as it meets the demanding homologation standards of this country. \\\\r\\\\n

MUSE Mobile Ultrasonic Equipment

The MUSE, a portable ultrasonic imaging system, was developed for in-field inspections of light-weig
ht structures. The MUSE consists of a motor-driven manipulator, a water circulation system for the acoustic coupling and a portable ultrasonic flaw detector (USPC 3010). The MUSE provides images of internal defects (A-, B-,C- and D-scan).

GEKKO - Portable Phased Array Testing with TFM in Real-Time

The portable phased array testing system GEKKO provides 64 parallel test channels. On creating testi
ng parameters the operator is assisted by the CIVA software. Due to its modular set-up the GEKKO instrument is suitable for operators of all skill levels.
