Hi All,
I posted a thread on FB about this and thought it would benefit some folk that might not have access to the CDG group on FB.
I have some old taper thread IWKA HOT cylinders, 21 cubic ft and 30 cubic ft. 2840 psi working pressure. Sorry I?m too old to tell you the metric capacity 😁. I bought them in the early 1990?s and, then, everyone quoted cylinder capacities in cu ft.
They are nice and light and great for longish transits to short sumps, or for a back up stage tanks. But it seems that the current Dive Shop cylinder testing regime; IDEST, will not touch them.
It was suggested I approach a tester of industrial cylinders, specifically a well respected company, CTS, who are based in Liverpool. http://www.ctsukltd.com. Thanks for the tip Chris J.
I contacted CTS who confirmed they can test HOT IWKA taper thread cylinders 👍
I dropped them off today and the costs are as follows
Taper thread Hydro test = ?15
Parallel thread test = ?16 (?1 for the new ?O? ring!)
Zinc & paint ?18
There is a 2 week lead time.
My cylinders were a bit battered so needed Zinc and pant.
The testing CTS carry out conforms to UKAS and Arrowhead standards. They were quick to mention that these testing standards exceed the IDEST requirements 😮.
See weblinks I found

They might pass, might fail, but at least they will test them.
