适用范围：This part of ISO 12004 specifies the testing conditions to be used when constructing a forming-limit curve(FLC) at ambient temperature and using linear strain paths. The material considered is flat, metallic and ofthickness between 0,3 mm and 4 mm.NOTE The limitation in thickness of up to 4 mm is proposed, giving a maximum allowable thickness to the punchdiameter ratio.For steel sheet, a maximum thickness of 2.5 mm is recommended.
