I have a LUXFER p12e-1 air tank thinking to send it of tomorrow for a retest as its been out of date for a while death date is 2020/05 would it be worth sendibg of to sell if it passes test?
It has 7 years of life, so is just over half way through
To get its full lifetime will still need two tests, one now to get it usable, and one anytime from 2015 to 2018 (EG test now and it's valid to 2018, but will have 2 years left when the current test expires)
Best if you can test without paying for postage
As for resale value fibre cylinders often go for about £80 irrespective of the lifetime
A depreciated value would be a little complex depending on the buyers opinion on retesting for 2 years
So it would either be worth 5 years of life - (estimated 15 year lifetime cost £200, so cylinder with 5 years life is depreciated to £66, or if you count 7 years then its depreciated to £93, but you have to deduct the last test to achieve that remaining life = £68 (assuming a test without postage) with limited life on the last test gaining only 2 years a test over £25 isn't realy financialy viable)
The 'value' based on a comparison to it as a second hand cylinder as opposed to a new cylinder is in the region of £60
Basic answer is yes - it's worth testing
If doing so to sell on then its best done sooner then later to maximise viability
