le-cerveau Posted December 6, 2017 Share Posted December 6, 2017 As I get ready to go to the next stage I need to prepare for MVHR testing but I am looking for collected advice: The regulations state that systems need to be “commissioned in accordance with a procedure approved by the Secretary of State.” (Regulations below): This is the Part L1(b): This is Part F1(2): Throughout it refers to procedure approved by the Secretary of State. From the Domestic Ventilation Compliance Guide Table 8 this is the approved procedure: This talks about UKAS accredited calibration. In the BSRIA guide there is details about calibration: After all that I have come up with the following: I need to use the approved methodology. The equipment need to be calibrated and in date. The calibration needs to be UKAS, and not just traceable. The calibration need to be volumetric not speed. 1 &2 easy, 3 and 4 not so. And comments advice.

Jeremy Harris Posted December 6, 2017 Share Posted December 6, 2017 I think we've all found that, in practice, BC just aren't interested in calibration certs etc. A pretty simple report seems to satisfy BCOs in every case I've heard of. Mine wasn't even glanced at during the completion inspection........... Link to comment Share on other sites More sharing options...

Auchlossen Posted December 6, 2017 Share Posted December 6, 2017 When I found that BC didn't even want a certificate or report, I rather lost interest in precise calibration. Link to comment Share on other sites More sharing options...
