Temperature Qualification

Temperature qualification  is the process of qualifying and certification of assets which are used for critical applications. This ensures  that the tested item is capable of maintaining the specified critical parameters throughout thdifference-between-mapping-study-and-qualificatione entire area under normal operating conditions. Such a test and certification will provide an insight into the performance aspects of the equipment or the enclosed area.

Temperature is a major parameter to be tested for qualifying an equipment. However, this need not be the only parameter or the main parameter to be tested depending on the application and type of equipment. In the article, we mainly explain about Temperature Qualification.

What is Difference between Mapping study and Qualification?

This is often a subject of confusion which we will like to clarify. In brief terms, qualification is much more elaborate process than a mapping study. A mapping study only analyzes the distribution of temperature and humidity (if applicable). The result will show whether the distribution is uniform. Mapping study is only one part of the qualification process. The qualification procedure has a lot of other verification and tests. These are to check whether all the major equipment is installed and being operated properly. Also whether they are capable of achieving the desired temperature and humidity. Eg. If a cold room is qualified for 1-8 Deg C, it means that the entire cold room and associated machines are capable of maintaining the temperature of 2-8°C. Nowadays all international pharmaceutical companies prefer  their distributors to have qualification for their critical assets such as cold rooms, vans, boxes etc.

The following are some of the major assets for which the process is applicable and temperature is one of the main factors to be tested:

 

  1. Cold room for keeping medicine, vaccine, food , consumer goods etc.
  2. Refrigerators for keeping medicines, vaccines.
  3. Freezers below 0°C which keep vaccines, frozen food etc.
  4. Cryo Freezers for keeping Cryogenic items.
  5. Reefers used for transporting medicines over long distances.
  6. Vans used for transporting medicines for local distribution.qualification-process-flow-chart
  7. Insulated Boxes which keep medicines under controlled temperature for a small duration such as 24 hours.
  8. Thermal Insulated Containers which keep medicine with or without auxiliary power.
  9. Stability chambers which have controlled temperature and humidity environment.
  10. Humidity Chamber having controlled humidity environment.
  11. Incubators (Temperature & Humidity)
  12. Clean rooms having controlled temperature, humidity and particle count.
  13. Trailer and Trucks, Reefer trucks used for consumer goods, perishable items, FMCG, frozen food, fruits and vegetables.

 

Temperature Qualification Process

The process involves various type of tests carried out as per the protocol specifically prepared of reach equipment and client. Irrespective of model and type of the tested piece, the protocol need to be specifically prepared for each device and to be tested separately. The process is classified as under:

  1. Design Qualification

    Temperature Qualification of a Reefer

    The design of the equipment should be adequate to achieve the desired results. The results are not to be defined by the installed equipment. eg. A cold room should maintain a temperature of 2 to 8 Deg Celcius for keeping medicines.Here the desired result is that the temperature should always  be within this limits. Hence all the installed equipment should be suitably designed to ensure the same.

  2. Installation Qualification

    This process involves various checking to test

    • Various components are properly calibrated periodically.
    • The equipment is properly maintained as per the recommendations of the manufacturer.
    • The equipment is operated as per the recommended operational procedures of the manufacturer.
  3. Operational Qualification

    This procedure involves checking all aspects affecting operations of the equipment. Among various other tests, this involves checking various controlling instruments of the asset to ensure that the asset can be properly controlled. eg. a Thermostat of a freezer is a controlling instrument, which if not working properly will affect the operation of the asset.

    Temperature mapping study also is generally a part of the procedure which is explained separately in this article.

  4. Performance Qualification

    The performance of the equipment varies as per the distribution and the type of material kept inside the area. Hence it is important to test the equipment under all such circumstances. The whole process will involve rigorous testing for extreme conditions to ensure the reliability of the same.

You may contact us for any specific protocol requirements such as SFDA temperature mapping protocol, NHS cold shipment validation protocol etc.

If all the above tests and verification are completed successfully, the temperature qualification process of the asset is completed and is certified in its entirety. It is possible that certain deviation or non-conformances may be observed during the processes. These need to be rectified and retested based on the criticality and the qualification process will be completed.
