Went to get a 30# propane tank refilled last week and was told it needed to be inspected prior to being refilled. I thought the certification was 12 years and I was a few months shy of that. I needed the propane, so paid the $7 fee for a 60 second soapy water test and got a new sticker for the tank that allows it to be refilled for 5 years.
Here's what I found with a Google search today; lifted from lpgasmagizine.com:
"The rule reduces the initial requalification period for DOT cylinders from 12 years to 10 years from the date of manufacture. It reduces the period from 12 years to 10 years for cylinders requalified using volumetric expansion testing. However, the requalification period for DOT cylinders following a proof pressure test increases from seven years to 10 years. The five-year visual inspection method for cylinder requalification does not change."
The new rule was effective 23 January 2018.
