Title: Room integrity tests- methodology
Post by: kurnal on September 05, 2011, 11:01:44 AM: Please does anybody have access to a document outlining changes to the integrity testing procedures under BS ISO 14520- the 2000 edition and the 2006 edition. I believe Bob Whitely did an article on it in the 1 September 2006 edition of FSE online but cant find that either.

I think the changes were to do with concentration levels at the height of the highest risk in the room rather than at lower levels as per the earlier standard, I dont mind buying standards but am loath to pay for an obsolete standard just to identify the changes!

Yes its part 1 and in particular appendix E - I have the 2006 version (even though I am not sure if I would understand the differences if I did read the 2000 version).

For that reason I was hoping to find a document summarising the changes

Thanks for pointing me in the right direction.

As for my bedtime reading it looks just the ticket. zzzzzzzz

Post by: Tom Sutton on September 05, 2011, 10:30:24 PM: I had a look at appendix "E" and that's more frightening a much better ~~aphrodisiac~~ soporific, I better stick to the blue guide. ;D

Pah! What a load of academic guff!

"And the value for dimensionless time is calculated as 5318008"
"How long is that then?"
"It's dimensionless"
"Is it something to do with time?"
"Yes"
"So how long does it last then?"
"It's dimensionless"
"Is it in seconds?"
"It's dimensionless!"
"You just wanted to have something that spelled 'BOOBIES' when the calculator was turned upside down didn't you?"
"Yes I did."

Post by: BLEVE on September 08, 2011, 06:15:35 PM: It can be any dimensionless parameter and not exclusively related to time. It is nondimensionalisation in relation to the use in any differential equation. Still a load of b*****x mind

Post by: CivvyFSO on September 11, 2011, 10:43:46 PM: I think we ultimately agree on something BLEVE. I think we should leave it at that.
