[askingwhy]

What is the section of Indication Types(for Magnetic Particle Inspection) in API 1104 20th ed.? (It contains "false indications","relevant indications")

 

[ndeguy]

API 1104 9.4.1. Classification of Indications. But follow through with referenced document ASTM E-709 to ASTM E-1316 Standard Terminology for NDE.
Para 1.3 and the accompanying diagram show the decision process for interpretation and evaluation of indications and Section A defines the terms used in that paragraph.
