In the long-term use of our in-house radionuclide method we have gained experience and numerous data, which serve as the basis for a constant further development of this method. Within the scope of a research project, the question has been raised as to how the carrier for technetium can be optimized in order to better identify problems during cleaning.
The removal behavior of a test soil or the cleaning performance of cleansers is examined under controlled conditions depending on concentration, temperature, and exposure time. For this purpose, a defined amount of clotting sheep blood is applied to a larger number of test samples.
After conditioning the test devices are subjected to a cleaning process and subsequently evaluated.
Since 2007, SMP GmbH is contributing to research projects and interlaboratory tests together with other renowned laboratories to reach a standardization of test soils for the ISO/TS 15883-5.
The background of this work is that there is no standardized test soil for evaluating the performance of washer/disinfectors. Same is true for suitable detection methods.
According to the standard EN ISO 11140-04 „Non-biological systems for use in sterilizers - Part 4: Specification for indicators as an alternative to the Bowie and Dick test for the detection of steam penetration“ alternative Systems are tested with respect to the detection of lack of steam penetration in the sterilizer.
This is achieved by simulating relevant faults in an especially equipped steam sterilizer.
