About ASTM E2737
The standard ASTM E2737 describes the evaluation of DDA systems for industrial radiology. It is intended to ensure that the evaluation of image quality, as far as this is influenced by the DDA system, meets the needs of users and their customers and enables process control and long term stability of the DDA systems.
These tests are to monitor the system performance for degradation and to identify when action needs to be taken if the system degrades by a certain level - i.e. influenced after repairs, hardware / software upgrades.
