This Standard specifies the performance of computed radiography (CR) systems and the measurement of the parameters for the system scanner and storage phosphor imaging plate (IP). It describes the classification of these systems in combination with specified metal screens for industrial radiography to ensure that the quality of images (as far as this is influenced by the scanner-IP system) is in conformity with the requirements of AS 2168.2.Manufacturers tests are described, which allow the determination of exact system parameters. Simpler user tests are also described, which are designed for a fast test of the quality of CR systems and long term stability.The classifications can be determined accurately by the manufacturer tests as described in this Standard. Individual test targets, which are recommended for practical user tests, are described for quality assurance. These tests can be carried out either separately or by the use of a CR Phantom (see Appendix B).
