Hello,

I have a question concerning cvn testing to AWS D1.5. When calculating the average ft/lb for the 5 weld metal cvn samples are the high/low values excluded or are all five specimens averaged?

Thank you.

I am pretty new to this... I am currently studying the D1.1 for exam next month. I am only replying because I just went over this last week. If it's not specified in D1.5, D1.1 4.37.3 stipulates that the high and low should be discarded, average derived from the remaining 3 and that 2 out of those 3 shall equal or exceed the minimum average value.
