The new  BS EN ISO 18119:2018 Gas Cylinders-Seamless steel and seamless aluminium-alloy cylinders and tubes – Periodic inspection and testing has been issued which supersedes BS EN 1968:2002 and BS EN 1802:2002

The standard recommends:

Local regulations will specify the interval of periodic inspection and test. In the absence of any local regulation as a guide, an internal examination every year with a periodic inspection test as 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.’

The last sentence was inserted at the last minute by the concerted efforts of the UK Recreational diving community, who have also prepared the attached Risk Assessment, which will mean that for the majority of ScotSAC members the current 2.5 year cycle will remain provided the good practice noted in the Risk Assessment is followed.

Members should be aware that these regulations will require cylinders to be tested annually unless compliance with best practice outlined in the risk assessment can be demonstrated.
