The new standard for cylinder periodic inspection and testing ISO 18119 is likely to be published later in 2018.

BSAC, as the National Governing Body for scuba diving, is maintaining an ongoing liaison with all elements of the diving industry that may be affected by this. Part of this liaison has been to obtain a clarification statement from Luxfer on the inspection and testing of aluminium alloy cylinders - read the statement from Luxfer.

As a diver please check to see if any of your cylinders are manufactured or suspected to be manufactured from aluminium alloys HE30/AA6082 or AA6351. Check for specific alloy-related markings or for a manufacture date (the earliest date stamped on the cylinder) prior to 1995. 

Please read the HSE’s safety alert for further guidance on how to check your scuba cylinders -  Cylinders manufactured from aluminium alloys HE30/AA6082 and AA6351 and used primarily for gases for underwater breathing apparatus.
