Q about PIR's

[LukeScotty]

ritey, just outta interest on domestic installations, on pir's do you have to test 100% of the installations?

hi there.
Providing your tests at the board are ok (ze pfc I/R) then you need only test 25% of the installation. (if in your opinion, the installation visually is good)

Hope this helps.

In GN3 it says the following:

Where sampling is applied, the percentage used is at the discretion of the tester. However, a percentage of less than 10% is inadvisable.

So I guess it really depends on how bad the Install looks for further investigation?
