A series of two or more Type F specimens may be used to cover the full thickness of the plate. Alternative test specimen may be used in place of the standard test specimen. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? The Type B specimen provides a reduced section length of 21? Strains in the through-thickness direction can cause individual inclusions to fractures or decohere from the surrounding steel matrix, thus initiating a void.

This specification covers procedures and acceptance standards for the determination of reduction of area using steel plates as tension test specimen. It’s easy to join and it’s free.
