Hollow Load Test
gke Steri-Record® process monitoring systems (PMS) are used for routine monitoring in steam sterilization processes in each cycle to detect insufficient air removal, leaks and/or non condensable gases (NCG) in steam. The PMS is a hollow load test which is designed to monitor steam penetration at the most difficult positions inside of the sterilization load. Monitoring temperature and pressure alone does not provide sufficient information to ensure steam penetration.
This PMS simulates the penetration requirements of simple hollow devices, tubes, porous loads and solid instruments. However, this PMS is less demanding regarding air removal and steam penetration than the hollow load test described in EN 867-5. The daily use as a process monitoring system has to be validated according to the reference load configuration during the performance qualification (PQ).
