Abstract

Both NB/T47013.2 and DL/T 821 are widely used in radiographic nondestructive testing of power plant boilers. This paper analyzes and compares the main differences between the two standards from three aspects: evaluation range, quality classification and radiographic process, and points out the improvement measures of DL/T 821 standard for boiler radiographic nondestructive testing.
