Bar internal soundness
Bar internal soundness
(OP)
This is a query basically related to the language and its interpretations (my native language is Spanish).
A client request us: "Each rolled bar which will be used for tube manufacture shall be examined for internal soundness by taking macro specimens at each end of the bar".
My doubt is related to the word "soundness". Does it mean, free from defects? is it about inclusions content? pores? all of them?
Unfortunately my client (who did not make the specification) also has difficulties in interpreting it
Thanks in advance.

RE: Bar internal soundness
I wouldn't link it to inclusions or stringers which are more microstructural defects.
But relate it to pipe, porosity, cracks, lapps and those types of defects.
Normally when someone says this they give you an acceptance criteria.
A macro from each end is fine, but what is the standard? Simply that they are solid?

I fully understand that in order to evaluate some carachteristics a criteria is necessary. In this case my question was more of a lenguaje interpretation. Many times the literal translations do not show the real expectations of the person requesting it.

If you took it to extremes you could condemn a bar on the basis of atomic vacancies. (Don't laugh, I have interacted with adult engineers at mega EPCs who wanted to take requirements to almost such a ridiculous extreme.)
