Working on a airplane deicing vehicle. Would this reference give my nitrogen bottles a 12year hydro interval? They are Dot 3AA bottles, would this supersede the normal 5 or ten year Dot requirement? Vehicle use on airport only. Thanks
I am thinking no on the 12 year
Call the manufacture tech support and ask
