According to TEPD (PI), ADR 220.127.116.11 P200 table, re-test for a compressed air aluminum cylinder is every 10 years. There is no expiry date for these cylinders as long as they pass the retest requirements.
Please note the chart below and if the cylinder is used for a listed gas the testing period may need to be adjusted. For our normal user 10 year for aluminum cylinders used to contain compressed air is correct.
Each UN pressure receptacle that becomes due for periodic requalification must be requalified at the interval specified in the following table:
