Temperature mapping of storage areas ISO13485

Hi all, We had an audit last month and one of the non-conformities was as follows: Infrastructure qualification A temperature mapping exercise is not available in the Company therefore it is not possible to evaluate the hottest and coldest points representative of the worst conditions for placing the Data Logger. Temperature is controlled and monitored in all our areas, however, there was no temperature mapping qualification performed. Temperature mapping is required for e.g. storage of pharmaceutical products (GLP/GMP/GDP), however, I cannot find evidence this is a requirement for storage of medical devices. I would like to know if this is mandatory. Thanks in advance!

Yes, you are right when you say that temperature mapping is not mandatory or required in ISO 13485. However, what is required in point 7.5.11 is that the manufacturer must protect the product from alteration, contamination, or damage when exposed to expected conditions during processing, storage, handling, and distribution. If your warehouse is racked and tall or divided (to have more rooms), then temperature mapping is needed to make sure that the temperature distribution is equal, that is, that the products, regardless of where they are located within the warehouse, are stored at the same temperature.

If this is not the case, and your storage is in one room, of normal height, and you can prove that the temperature distribution is equal, then you can justify that temperature mapping is not necessary.
