Definition(s)
Relevant Indication
Any indication [liquid penetrant (LP) or magnetic particle (MP) examination] with a major dimension greater than 1.6 mm (0.062 in.).
- NOTE: Inherent indications not associated with a surface rupture are considered nonrelevant indications.

Relevant Indication
Surface NDE indication (iquid penetrant or magnetic particle examination) with a major dimension greater than 1.6 mm (0.062 in)

Relevant Indication
Surface-rupture NDE indication with major dimensions greater than 1,6 mm (1/16 in). NOTE Inherent indications not associated with a surface rupture are considered non-relevant.

Relevant Indication
Only those indications with major dimensions greater than 1⁄16 inch shall be considered relevant. Inherent indications not associated with a surface rupture (for example, magnetic permeability variations and non-metallic stringers) are considered non-relevant. If magnetic particle indications are believed to be non-relevant, they shall be examined by liquid penetrant surface NDE methods or removed and reinspected to prove their non-relevancy.
