A little knowledge can be dangerous,have not seen a cubic ft dial in at least ten years nor worked on low pressure reg for the same amount but i still have to know how to test and rate them,its known as competence

What do you mean by "Medium Pressure"???? if OP is more than 75Mb
you will need to test to IGE UP1 which is far and beyond a Domestic UP1/B test and will require the services of one or more operatives with the relevent qualifications!! icon_wink.gif

Medium pressure is in scope for CCN1. Not a problem testing and purging it on domestic ticket.

Maybe a bit confusing to some , gas service pipe up to medium pressue regulator will be 2 bar pressure as opposed to 75mb , tightness test is carried out @ 19mb.

Not in CCN1 any more.
A meter inlet valve should now be fitted after the governor to test installation.

What book are you refering too? , 5th edition-revised?

TT without MIV........ Let-by @ zero mb , TT 19mb.

TT with MIV.....Let-by @ 10mb , TT 20mb.

No MIV = NCS.

Does your refference material suggest otherwise?

Thanks.

Petite.
There is only 1 question on medium pressure and its a really basic one, think it was double ecv.


Monoxide yep its one of those trick questions where if asked it would be easy to answer either 19 or 20 but then have to explain what pressure is used and when.
