Permissible air loss in a dry pipe system

[ContractorDave]

I was responding to an article in a trade magazine and I was going to include the sentence from what I thought was NFPA 25 in regards to acceptable air loss in a dry pipe system - I recall from SOMEWHERE something along the lines of "Air loss of more than 10 psi a week shall be investigated and repaired" but for the life of me I can't find it in either the 25 or 13 handbook. Has this been removed or replaced by a variation on the theme, or am I remembering it from one of the AFSA or NFSA inspection reports?
