GB/T 23901.5-2019 Non-destructive testing—Image quality of radiographs—Part 5:Determination of the image quality unsharpness and basic spatial resolution value using duplex wire-type image quality indicators
Abstract
This part of GB/T 23901 specifies the method for determining the image blur and spatial resolution in radiographic inspection.
The double-wire type image quality meter specified in this part is suitable for tube voltages up to 600 kV, while the tube voltages suitable for double-wire type image quality meters exceeding 13 line pairs are less than 225 kV. When using high-energy radiographic inspection with a voltage exceeding 1 MeV, the double-wire type image quality meter specified in this part can be referenced, but the measurement results may have significant deviations.
