Dear all. I am new on this forum. I want to start with one question if you are kind to answer.

I have found in some companies that they use A106 Grade B in group 1 (conform to EN ISO 15608) even in the CEN ISO TR 20173 this material can be found in group 11 (according to the equivalence from EN to ASTM). I have attached a picture which says that the material was made according to ASTM, so it doesn't have any equivalence to EN.



But if we check the chemical composition of the material according to EN ISO 15608, the material fits in group 1.

So, it can be used as group 1 according to EN ISO 15608?

Thank you.
Best regards.
