Abstract��According to the requirements of the standard GB/T 228��2002 "metallic materials tensile testing at ambient temperature", the measurement uncertainty for the percentage elongation after fracture of cold��rolled austenitic stainless steel plates was studied in this paper. It shows that the uncertainty of percentage elongation after fracture is 2.0%, when k=2 and A=62.5%.��
