Qualification User Requirement Specification URS: Document to collect all requirements define usage very precisely (which kind of samples will be stored?) define climatic condition -nominal value, according ICH Q1A, WHO (e.g. accelerated conditions: 40 C ± 2 C / 75 % r.h. ± 5 % r.h.) - limits, according ICH Q1A, - additional conditions (e.g. Humidity in 5 C-Cells is not recommended, but very important)
Qualification User Requirement Specification URS: Document to collect all requirements define location, shape and area needed define equipment (shelves, drawer needed?) define safety and enviromental aspects (fire detector) define security requirements (on-line monitoring, locking system) define budget define basis and scale of qualification
Qualification analysis of local conditions Find the best location (building) for stability chambers consider flow line (Short way, minimal horizontal moving) infrastructure (water, air condition, additional deconstruction) safety and enviromental aspects (energy saving) security requirements (available access control-systems)

Qualification 1. Phase: DQ-Design Qualification Start need of a climatic chamber write and approve DQ-Plan getting different tenders Check technical manuals URS available write and approve DQ-Report (with reported open issues) before starting IQ End Order of the designed chamber
Qualification 2. Phase: IQ-Installaltion Qualification Start delivery of the climatic chamber write and approve IQ-Plan compare ordered and delivered material Installation of the climatic chamber according local requirements / standards first function check prepare a (technical) logbook Installation of additional equipment (monitoring sensor or flash-light) write and approve IQ-Report (with reported open issues) before starting OQ End installed climatic chamber
Qualification 3. Phase: OQ-Operational Qualification Start installed climatic chamber write and approve OQ-Plan OQ-tests with empty chamber: running of the climatic cell: does it work as expected perform extensive Temperature- and Humidity-Room-Mapping testing any influence of the climatic conditions (light, open doors) simulate a power failure and protocol the behavior of the chamber to make conclusions find a representative position for the monitoring sensor write and approve OQ-Report (with reported open issues) before starting PQ End Climatic chamber ready for operation
Qualification 4. Phase: PQ-Performance Qualification Start running / working climatic chamber (without samples) write and approve PQ-Plan repeat the OQ-tests with filled chamber: running of the climatic cell: does it work as expected perform extensive Temperature- and Humidity-Room-Mapping testing any influence of the climatic conditions (light, open doors) simulate a power failure and protocol the behavior of the chamber to make conclusions Go live with the on-line monitoring, if available Calibrate the sensors write + approve PQ-Report (without any open issues) End completely qualified climatic chamber
Qualification 4. Phase: PQ-Performance Qualification perform extensive Temperature- and Humidity-Room-Mapping Possible data logger positions to map temperature and humidity
Qualification data logger to collect temperature and humidity data
Qualification 1. Qualification of stability chambers: 1.1 General aspects 1.2 URS, analysis of local conditions 1.3 Qualification: DQ, IQ, OQ, PQ 1.4 periodic Re-Qualification 2. Calibration of equipment: 3. Maintenance of stability chambers:
Qualification Periodic Re-Qualification Start running climatic chamber Strategy: Review of qualification status after a pre-defined time period write and approve Re-Qualification-Plan check all relevant parameters (i.e. MSR) is the change documentation complete? Repeat the Temperatur- and Humidity- Room-Mapping write and approve PQ-Report before writing the Final Report End re-qualified climatic chamber
Calibration 1. Qualification of stability chambers 2. Calibration of equipment of stability chambers 3. Maintenance of stability chambers
Calibration concepts Calibration of equipment (e.g. sensors for on-line monitoring) in place Calibration including whole measured distance one point calibration at set point Calibration of equipment (e.g. data-logger for temperature mapping) with a certified, adjusted master tool (Certified Institution) Calibration without measured distance Multi point calibration all set points must lie within calibration range Data logger must be suitable for intended conditions (e.g. 40 C / 75%r.H.)
