按照GB/T 2282002《金属材料室温拉伸试验方法》标准的要求，对冷轧奥氏体钢板规定非比例延伸强度Rp0.2测量结果的不确定进行了评定。确定了当k=2时非比例延伸强度的不确定度。

According to the requirements of the standard GB/T 2282002 “metallic materials tensile testing at ambient temperature”, the measurement uncertainty for the Rp0.2 of coldrolled austenitic stainless steel plates was studied in this paper. The result shows that the expanded uncertainty of Rp0.2 is 8 N/ mm2, when k=2 and Rp0.2=270 N/ mm2.
