摘要

Reference System for checking a Liquid contained in a Container transparent to the Detection Method Descriptive The invention relates to a reference system for the non-destructive checking and detection of imperfections in a liquid in a container which is transparent to the selected method of detection. The system according to the invention is characterised in that it is composed of a set of identical standardized containers all containing the same liquid and each having a single known, deliberate imperfection which is stable and reproducible and capable of producing a signal in the detection system used and which varies in size from one container to another. For pharmaceutical checks the system may comprise in particular a set of pharmaceutical ampoules. The system according to the invention allows a high degree of accuracy and a saving of time to be achieved for automatic checking and also allows the quality of a visual check to be improved to an appreciable degree.
