I'd like to see the VIP sticker on your cylinder...
There is O2 cleaned for max 40% service...there is also 100% oxygen service cleaned...for either 100% oxygen service...and partial pressure fill service where 100% oxygen is introduced into the cylinder first...before it is topped up with 21 % (air)...
A cylinder that is cleaned for 40% oxygen service...cannot be filled by the partial pressure fill method...
Then there is the ''blend stick'' pre-mix fill method to 40% max...where the cylinder does not have to be oxygen service cleaned at all...
The best way to be sure is to always have your cylinders/valves cleaned for 100% oxygen service...and ensure the shop you use is always using hyperfiltered air...if not the cylinder will have to be recleaned...
Personally...I'm not a believer in a cylinder cleaned for max 40%...in my mind the cylinder/valve is either cleaned for 100% oxygen service...or it's not...
I've seen shops that claim to be performing 100% O2 cleaning on the cylinders...but leave the valves untouched...
The attached is the VIP sticker I use...with the appropriate punch-outs for 100% oxygen service cleaned...
This yellow/green VIP sticker also eliminates the need for large NITROX bands...
Hope this helps...
Best...

Dear Warren,
Thank you for this explanation.
As far as i understood from the Technician that serviced my tank they inspect it to be complete O2 safe as part of the regular VIP.
How ever, when ill get home in a couple of hours ill take a picture of the sticker and upload it here. I could be just mashing things up in my memory.
