Popis
BS EN ISO 19232-5:2018
This standard BS EN ISO 19232-5:2018 Non-destructive testing. Image quality of radiographs is classified in these ICS categories:
- 19.100 Non-destructive testing
This document specifies a method of determining the total image unsharpness and basic spatial resolution of radiographs and radioscopic images. The IQI with up to 13 wire pairs can be used effectively with tube voltages up to 600 kV. The IQI with more than 13 wire pairs can be used effectively at tube voltages lower than 225 kV. When using source voltages in the megavolt range, it is possible that the results are not be completely satisfactory.
