That doesn't sound correct. Here's the PDF from IDEST about ISO DIS 18119 UPDATEdated 12th May 2017Originally Posted by AlBur
Finally had to take my air cylinder for refilling. 7L, 300barg. As it was out of test a few years ago knew it required a full hydro test. However got a bit of a shock.
First I was informed that the pillar valve was a dive cylinder valve (I bought the complete setup from our sponsors several years ago. I assumed, incorrectly it would seem that the pillar valve was the correct "only to be used out of water" valve. The correct valve has the pressure gauge indicating the pressure in the tank being charged attached to the pillar & not on the connected filling line as mine is).
He added that it did not matter as the current ruling is that ALL cylinders must be hydro tested every 18 MONTHS. No more is it 5 years for an airgun only cylinder. Come August 2017 this may be reduced to hydro testing every 12 MONTHS. Again for ALL air cylinders. There is of course an interim dry internal check which must be carried out mid cycle. Cost for the hydro test is £35. To collect in a week, or so !!.
Anyone heard similar information.

...As many of you will know the current Cylinder Testing Standards BS EN 1802:2002 and BS EN 1968:2002 are in the process of being replaced with a new standard ISO 18119.
As this is an International Standard and not just a BS or EN, the adoption of the ISO standard is automatically undertaken by the countries who signed up to the ViennaAgreement in 1991 and this includes the UK.
The proposed ISO 18119 calls for annual visual inspections and a hydrostatic test every five years for Self-contained breathing air, O2, etc and Gases for underwater breathing apparatushttps://www.sita.org.uk/cms-assets/d...119-update.pdfThe standard now recommends:
“Local regulations will specify the interval of periodic inspections and test. In the absence of any local regulation, as a guide an internal examination every year with a periodic inspection test at 5 yearly intervals should be carried out.
However, if on completion of a risk assessment and the specific use of a cylinder indicates that there is a low risk of internal degradation then the interval for carrying out an internal examination can be increased to a maximum of 2.5 years”

It seems from reading the rest of that text that the ISO standard has not been fully decided, but that IDEST have taken that a stance. So all cylinders being hydo'd every 18 seems a bit off. I had a cylinder done for exactly that by my local dive shop recently who is very particular about regs (as he supplies are to the more extreme divers around here) and he made no mention of it.
