Sample temperature mapping dossier

A temperature mapping dossier is more than a graph with minimum and maximum values. It should show why the measurement setup was logical, how the study was performed, what the data mean and which storage and monitoring choices follow from it.

Example structure

Sample dossier aligned with WHO/ISPE principles

A temperature mapping dossier is more than a graph with minimum and maximum values. It should show why the measurement setup was logical, how the study was performed, what the data mean and which storage and monitoring choices follow from it.

WHO/ISPE

Based on the practical structure in WHO TRS 961 Annex 9 Supplement 8 and the ISPE Good Practice Guide for Controlled Temperature Chamber Mapping and Monitoring.

1. Document control and approval

Version history, author, review, authorization and any change history. When a third party supports the work, internal approval by the responsible organization remains necessary.

2. Scope, rationale and objectives

Description of the room or equipment, storage condition, use, loading, study period and purpose of the mapping, such as qualification, requalification or investigation after a change.

3. Site survey, risk assessment and 3D room overview

Dimensions, floor plan, racking, doors, HVAC, existing sensors, product zones and expected risks such as air discharge, solar load or height differences. A 3D room overview helps document the relationship between layout, risk zones and logger placement visually.

3D overview of room, product zones and logger positions for temperature mapping
Example of a 3D room overview: product zones, doors, airflow and logger positions are recorded visually.

4. Acceptance criteria

Predefined temperature limits, for example 2-8 °C or 15-25 °C, including any agreements on door tests, allowed recovery time and deviation assessment.

5. Measurement strategy and logger placement

Logger IDs, positions on drawings, placement rationale, heights, recording interval, start time, study duration and justification of representative and risk-based product locations.

6. Equipment and calibration

Data loggers used, serial numbers, calibration status, certificates, measuring range, accuracy and traceability to suitable standards.

7. Execution records and observations

Start and stop time, loading condition, door movements or access log, disruptions, moved loggers, relevant events and confirmation that loggers were positioned as planned.

8. Data analysis

Trend graphs, minimum, maximum, mean where useful, hot and cold spots, comparison with acceptance criteria and assessment of patterns by location, height and time.

9. Deviations, CAPA and impact

Temperature excursions, protocol deviations, missing data, possible product impact and any corrective or preventive actions.

10. Conclusion and recommendations

Conclusion on suitability of the room or equipment, safe storage zones, zones to exclude, monitoring position and any need for remapping.

Annexes

Typical annexes

Annexes make the dossier traceable and reviewable. Typical items include floor plans with logger positions, raw data, graphs per logger, calibration certificates, photos, access log, deviation reports and signed forms.

Floor planLogger positions, product zones, doors, airflow and existing sensors.
Raw dataDownload files, trend graphs and summary per logger.
CalibrationCertificates, serial numbers and traceability of the loggers used.
DeviationsEvents, door movements, excursions and any CAPA or remapping advice.
