Abstract��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.

Key words�� cold��rolled austenitic stainless steel plates uncertainty
