Interested to know what other people do about IR testing results on a MWC. If your additions contain new fixed wiring then you test that and record those results, obviously. But what if you're just replacing a fitting with a brand new one, the IR testing of which seems pointless? Do you leave blank or strike through these entries (which are in a section called "Essential Tests")? You're not under any obligation to IR test the existing wiring you're connecting/adding to to sign off the MWC IMHO.
