This document specifies testing conditions for use when constructing a forming-limit curve (FLC) at ambient temperature and using linear strain paths. The material considered is flat, metallic and of thickness between 0,3 mm and 4 mm.<\/p>\n

\n
\n NOTE\n <\/div>\n

The limitation in thickness of up to 4 mm is proposed, giving a maximum allowable thickness to the punch diameter ratio.<\/p>\n<\/div>\n
