used with each application in the QC Plan. Do not start work until the QC Plan has been reviewed and the JMF has been submitted. When unsatisfactory results or other conditions make it necessary, a new JMF may be required. If a change in sources of materials is made, submit a revised JMF to the DME/DMM before using any new material.
