标准摘要
[中文适用范围]： 本文件规定了在环境温度下构建成形极限曲线 (FLC) 并使用线性应变路径时使用的测试条件。 所考虑的材料是扁平的金属材料，厚度在 0.3 毫米到 4 毫米之间。 注：建议厚度限制为 4 mm，给出了最大允许厚度与冲头直径之比。 [外文原描述]： 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. NOTE The limitation in thickness of up to 4 mm is proposed, giving a maximum allowable thickness to the punch diameter ratio.
