In this phase several new procedures have been developed regarding the use and maintenance of equipment that should be described in the SOPs specific for each piece of equipment. An example is the procedure for calibration and maintenance. This procedure is highly specific for each piece of equipment and should therefore be added to the Equipment SOP specific for every piece of equipment.

In phase 2 the document control system will be launched. This system ensures that all the SOPs of the laboratory are reviewed and, if necessary, revised annually. Read through the Equipment SOPs and see which SOPs need to be amended with procedures developed in phase 2. Write these procedures on a Document Revision Form (developed earlier in this phase) and place this in front of each SOP. This way the author of each SOP knows what to adapt when he must review and revise the SOP.
