W artykule zaprezentowano wybrane wyniki badań nieniszczących środków bojowych znajdujących się na wyposażeniu Sił Zbrojnych RP, wykonanych aparatem rentgenowskim typu MU-17F-225-9 firmy YXLON. Badania prowadzono w celach diagnostycznych, ze względu na ich ogromne znaczenie w procesie oceny stanu środków bojowych. Uzyskane wyniki decydują również o wyborze metodyki późniejszych badań.

Some results of non-destructive tests of explosive ordnance (munitions) used by the Polish Armed Forces and performed by X-ray apparatus MU-17F-225-9 from YXLON are presented in the paper. Tests were performed in diagnostic purposes as they are significant for munitions status evaluation process. Received results decide also about the selection of final testing methodology.

The forecast of structure and properties of casting is based on results of computer simulation of physical processes which are carried out during the casting processes. For the effective using of simulation system it is necessary to validate mathematica-physical models describing process of casting formation and the creation of local discontinues, witch determinate the casting properties. In the paper the proposition for quantitative validation of VP system using solidification casting defects by information sources of II group (methods of NDT) was introduced. It was named the VP/RT validation (virtual prototyping/radiographic testing validation). Nowadays identification of casting defects noticeable on X-ray images bases on comparison of X-ray image of casting with relates to the ASTM. The results of this comparison are often not conclusive because based on operator's subjective assessment. In the paper the system of quantitative identification of iron casting defects on X-ray images and classification this defects to ASTM class is presented. The methods of pattern recognition and machine learning were applied.
