Updated: 1 day ago

A formal GMP document that defines how a temperature mapping study will be planned, executed, monitored, and evaluated to prove that a storage or processing area consistently maintains the required temperature conditions. It is a pre-approved, controlled document and forms the basis for qualification and regulatory compliance.


Purpose of a Temperature Mapping Protocol

The protocol ensures that temperature-sensitive products are stored or handled under validated and uniform conditions. It demonstrates compliance with GMP, GDP, WHO, FDA, EU GMP, and other regulatory expectations by providing documented evidence of temperature control.


Temperature Mapping Protocol may contain

  • Objective and Scope

  • Regulatory References

  • Responsibility Matrix

  • Equipment and Instruments

  • Design of the Study

  • Acceptance Criteria

  • Execution Methodology

  • Deviation Handling

  • Data Interpretation

  • Recommended Changes

  • Requalification
