Temperature mapping from scratch
Plan, run, analyse and report a mapping study that stands up to a GDP or GMP inspection — in the order the work actually happens.
12 articles · about 39 min · for QA, validation and facilities engineers running their first (or first defensible) mapping study.
- 01Temperature MappingWhat is temperature mapping?Why regulated storage spaces are mapped, what a study produces, and how the results are used.6 min
- 02Temperature MappingWhat GDP expects from temperature mappingEU GDP asks for an initial mapping exercise before use, repeated after significant changes — and for the results to drive where monitoring equipment is placed.3 min
- 03Temperature MappingWhat a temperature mapping protocol should containThe protocol is the contract for the study: fix the purpose, limits, sensor plan and analysis rules before a single logger is placed.3 min
- 04Temperature MappingHow many sensors are needed for temperature mapping?There is no single number: sensor count follows from the geometry, the risk points and the acceptance limits of the space.3 min
- 05Temperature MappingSensor placement principles for mapping studiesPlace sensors where product is, where risk is, and where the monitoring probe might go — and write down why.3 min
- 06Temperature MappingChoosing sampling interval and study durationA 30-minute logging interval does not blur an excursion, it deletes it. A 17-minute event peaking at 9.64 °C is caught at 1 minute and invisible at 30.3 min
- 07Temperature MappingEmpty versus loaded mapping studiesAn empty space shows the equipment; a loaded space shows what product will experience. Most qualification approaches want both.3 min
- 08Temperature MappingSetting acceptance criteria for a mapping studyAcceptance criteria come from the product's storage condition: limits, a definition of a permitted excursion, and a rule for what happens at the boundary.3 min
- 09Temperature MappingData-quality checks before analysing mapping dataStatistics computed on bad data are precise and wrong. Check the data first.3 min
- 10Temperature MappingHow to identify hot and cold spotsHot and cold spots are defined by the data and the limits together — and the definition should be fixed before the analysis starts.3 min
- 11Temperature MappingWhat a temperature mapping report should containA report is a technical record that lets a reader who was not present understand what was done, what was found and what was decided.3 min
- 12MonitoringChoosing monitoring locations from mapping resultsPermanent sensors go where the mapping found the worst case — the hot spot, the cold spot, the slowest-recovering position — not where the cable reaches.3 min
