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!! ;)
 
I take it he is on about standard domestic meter set up and that is nothing special
 
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.
 
monoxide .read the pages in the book before it mentions19 mb

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.

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.
 
Why don't you read your books in stead of asking silly questions here? All you need to know for you exam is in there.
