I am interesting to see you use 'nuances', but i think it's true.
Here is something even more funny.
NB inspect and adult the manufacturers on behalf of ASME. If manufacturer pass it, they will have ASME certificate which is they should do, but they also will have NB certificate.
See, one visit...
My company has got the ASME certficate, but all the certifcation is issued by NB.
And some details of our product have been published on NB website
Why? What's the relationship between ASME and NB?
