Reference block for pipe longitudinal weld seam inspection with phased array UT

Dear All, I would appreciate if anyone advice which code and/or standard specify the requirements for reference block for pipe longitudinal weld seam inspection using phased array UT
Thank you

European standards don't indicate any rules for reference blocks for phased array method. Actually the type of the reference block depends on what kind of flaws you wish to detect. If the diameter is large enough (EN 583-2 requirements for probe dimensions) and the thickness is equal/more than 8mm you can utilize reflectors used in standard manual UT such as 3mm diameter side drilled holes (used for DAC method). The only case is that you have to create DAC curves for angle beams that you use in the further examination i.e. 45 60, 70 [deg]. If you do it this way you will meet the reqiurements of the EN 583-2 and EN 1714 about the number of angles and you can replace the old manual UT with the phased array

All depends on the potential of your defectoscope (u may have a software that can provide DGS curves) and the application. If you seek for a particular type of flaw/imperfection it's better to use a reference block and reflectors simmilar to the expected defect. I'm not going to give you exact directions for the test block because it requires lots of calculations and the reference piece needs to fulfil the reqiurements of EN 583-2 (apendixes)
I hope that I helped a bit
