Look, you seem to have got your back for some reason, but if you don't explain the context or why you need the test and what it needs to demonstrate and to whom then the thread's gonna keep going round in circles.
If I asked someone in the street did they know where the Post Office is, they wouldn’t ask why do I need to know or for what reason do you need to know where the Post Office is.
I asked, did anyone know of the certification of an air blower/air tightness/smoke test, although it’s not needed for building regs.
Then I elaborated further and provided YouTube footage, that’s more than enough, I want an industry standard certified report, to give any such test credibility, that’s it.
A test and written report has credibility when backed up by an industry standards verification from the relevant certified body.
So if the relevant Certification doesn’t come to mind when you read my post, then you don’t know the answer.
