Boat or Scoop Test

[Leo_IWI_EWI_MSc_BSc]

Hi,
Could someone tell me that the applicable standard to Scoop Test or Boat Steel on steel?. I can not find an specific reference in ASME VIII, Div.1 or 2.

Non-Destructive Scoop Sampling - Stress Engineering Services, Inc

Stress Engineering develops and validates a wide range of material condition assessments using specimens cut from small scoop samples.

Thanks in advance.

This is a very new technology as I understand from the link.The company that does this would be able to refer to relevant inspection standard. ASME Sec V has not included it yet.
The first thing that comes to my mind is that, in some oil and gas industries, there is a trend to usher in new inspection techniques, and this could be one.
However, its applicability seems quite limited as conventional inspection methods do quite well.

That looks like a much shallower version of a trepanning cutter. I've used trepanners to cut out crack tips in-situ on large machines. Unfortunately trepanners cut a rounded wedge that is quite deep and destructive. You may find value studying standard practices for trepanning.

This technology is interesting as a way to get physical samples without necessarily losing fitness for service.

This is a variation of an old method.
This has been done for decades when you have to positively identify material (and its HT condition).
Often these sites are then weld repaired.

As Ed stated, the boat sampling method has been used for decades and the site often requires repair by welding. The scoop sampling method is much more shallow and often doesn't require weld repair; it has also been used for at least 20 years.
