Danfer,

there were posted some great responses a time ago at the same topic, as I could see.

Have you for instance tried to get in contact with the manufacturer of the steel, as Prof. Crisi has recommended, or considered eventually the advices coming from Goose-em or js55?

I can remember there were quite many discussions in the forum dealing with CV-testing, amongst others e.g.

http://www.aws.org/cgi-bin/mwf/topic_show.pl?pid=53256;hl=Charpy%20V#pid53256

Please have a look as well upon the attached file, but however, I would seriously bear in mind the posts coming from the above mentioned experts.

Best,
Stephan
