| Zusammenfassung | In legal metrology, protection against manipulation and quality assurance of software-controlled instruments are becoming increasingly important in view of the introduction of a modular conformity assessment procedure for industrial products and the increasing use of such measuring instruments. However, neither commonly accepted approval procedures nor quality assurance systems for software used in measurement instruments exist. it was the objective of this project to fill this gap. Under certain conditions a software analysis is necessary in an approval procedure as well as in quality assurance. Software analysis requires special know-how and is very costly. In the project technical aids have been developed which reduce the expenditure of examination and make the examination procedure more systematic. A program is described ("examination assistant") which is designed for registering and modelling a complex measuring system. This program decides whether a complicated software analysis is necessary according to the standard in legal metrology. The software examination itself is performed by another program ("DFA tool", or Data Flow Analysis tool). It has been constructed on the Basis of a data flow model and of structured software requirements. The examination assistant collects all data necessary for the data flow analysis from the knowledge gathered before. After the analysis of data flow the examination assistant receives the results and interprets them. The state of the art achieved at the end of the project results in a technical aid which is ready to be used in practice. Apart from some minor technical restrictions and handling difficulties, the essential features of the tools have been realized. |
