Hello HyunJoo

My opinion (no such thing as definite answers in NDT - everything is ring-fenced with conditions) as follows;

1) Definitely - I think that's an easy one with no explanation/clarification required

2) Definitely (though I did start typing "Hmmm"). You need to know that indications are not caused by using the wrong process, e.g. use of post-emulsiifiable penetrant on a rough-surfaced, unmachined casting or that defects have been missed through insufficient penetranetdwell time.

3) The easy answer is to say "Yes" again, and therefore Yes also to (4) and No to (5). I WILL say yes as the penetrant lab should have a Technical Instruction or Procedure available for each particular part with ALL relevant information on it.

Regards

Nigel
