Temperature mapping is a method to determine the hot and cold spots of an area so that sensors can be installed for permanent registration. It is a vital process for the verification of temperature controlled areas such as freezers and conditioned storage areas. Besides determining hot and cold spots, temperature mapping also makes clear whether or not the temperature is evenly distributed.
Some protocols call for mapping every three months while others can suffice with yearly. The validation plan should take into consideration any seasonal impacts such as weather changes or product volume trends. Any major event in the facility such as construction or HVAC changes could justify an unscheduled validation run. Consider these variables when making your frequency decisions.
Be sure to plan the duration of your study for a realistic period of time that represents an adequate sampling of what the environment is exposed to. For instance, make sure the testing period covers weekends, when there may be little or no activity and also during a busy time when doors are constantly being opened and closed. Depending on the workflow of the facility, this may be more efficient to do in several small studies versus one long one.
