Sec. 820.181 Device master record (DMR) states, in part "...(b) Production process specifications including the appropriate equipment specifications..."
Sec. 820.184 Device history record (DHR) requires, in part"...to demonstrate that the device is manufactured in accordance with the DMR..."
So, the DMR has to include equipment specifications, and the DHR has to show the DMR was followed. I think this answers your question as far as which piece of equipment is approved (and used) for the product.
