Thermal mapping starts with a defined question.
Which space, under which conditions, against which limits? Scope a temperature mapping study for your warehouse, cold room or other controlled environment before setting the deployment and reporting plan.

A new storage area, a changed layout and an investigation are different assignments. Tell us which decision the study must support.
- Warehouses
- Identify the storage zones, usable rack heights, receiving or staging areas, and any seasonal conditions you want considered.
- Cold rooms and freezer rooms
- Provide the target range, usable storage volume, loading state and operating schedule. Discuss any door-opening, recovery or power-loss tests separately.
- Chambers and other equipment
- Share the equipment type, model, intended use and study requirements. Suitability and the required methodology are confirmed during scoping.
Specify the documentation in the quote
Use this as the deliverable checklist for the proposed engagement. The written scope confirms what is included and who prepares, reviews and approves each item.
- Protocol and placement plan
- Study boundaries, conditions, acceptance criteria, recording interval, duration, sensor locations and responsibilities, ready for the agreed review process before execution.
- Study evidence
- Sensor identification and relevant calibration records, recorded data, placement records, and the operating events or deviations documented during the study. Confirm the required file formats.
- Analysis and report
- Results against the agreed criteria, observed hot and cold locations, limitations and recommendations. Define any additional calculations, review rounds or supporting documents in the scope.
Keep the scope boundaries visible
- No universal study duration
- Collection time and total project lead time are separate. The protocol defines collection time; access, operating cycles, seasonal needs and document review affect the schedule.
- Not automatically included
- Equipment repair, HVAC changes, ongoing monitoring, alarm commissioning, broader qualification work and repeat studies after corrective action require their own agreed scope.
- No blanket compliance guarantee
- A completed study is not a regulatory approval or an unconditional pass. Your quality team must review the findings and decide what further action is necessary.
Bring these inputs to the first conversation
- Site and space
- Location, number of areas, dimensions or volume, usable storage height, and a layout if available. We confirm service availability for your location during scoping.
- Use and timing
- Stored products and target ranges, normal loading and access patterns, the reason for mapping, your deadline, and any access or shutdown restrictions.
- Quality and documentation
- Applicable internal requirements, existing protocols or studies, required deliverables, and the person responsible for protocol and report review.
Methodology and further reading
WHO describes mapping as a documented study of temperature distribution, including hot and cold locations. Its methodology separates protocol approval, execution, reporting and follow-up actions.
- WHO: Temperature mapping of storage areas, Supplement 8 (2015)
- ATEK guide to USP <1079.4>
- ATEK guide to ISPE temperature mapping
These resources inform scoping; they do not determine which requirements apply to your facility. Your quality team confirms the applicable requirements and approves the protocol.
