For example, I have a flow-down list of document numbers, however it only lists one form number for a calibration list, using F-715-001. Currently we have a calibration form for each piece of lab equipment. Same form just, individual form for each thermometer, balance, etc. Would this form then be F-715-002?
New version of the standard doesn't change the coding system, so you can keep the existing one and there is no reason for change. What will change during the transition are the documents themselves and their version number should be changed but they can have the same identification code.
