摘　　要：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/ mm^2 , when k=2 and Rp0. 2=270 N/ mm^2.
