The population of stainless steel cylinders used for pressurized beverages is over 25 million, and the population of LPG stainless steel cylinders is over 4 million.
This experience of stainless steel cylinders has shown that there was no problem of ageing, and that the burst pressure remains within the specification. Periodic inspection is normally carried out at a test station operated under the responsibility of a competent gas organization, or of a third party. This European Standard calls for the use of substances and procedures that can be injurious to health if adequate precautions are not taken.
It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. Where judgements are called for, it has been assumed that they are made by competent persons who have been trained specifically for the tasks.

1 Scope This European Standard specifies inspection intervals, procedures for periodic inspection and testing, for transportable refillable welded steel LPG cylinders of alternative design and construction of water capacity from 0,5 l up to and including 150 l (see EN 14140). This European Standard does not apply to cylinders permanently installed in vehicles, or to plant and filling equipment. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

An interval of 10 years shall apply if any of the conditions specified in Annex A are not met. The inspection procedures to be applied shall be selected from the alternatives given in Clause 5. 5 Procedures for periodic inspection 5.1 General Procedures for periodic inspection shall consist of an external visual inspection as described in 5.2 and, additionally, at least one of the procedures described in 5.3. Periodic inspections/tests shall be carried out under the responsibility of a body approved by a competent authority. Cylinders rejected shall be segregated to be reconditioned, re-tested or rendered unserviceable. The decision to render a cylinder unserviceable may be taken at any stage during the periodic inspection procedure.
With the agreement of the owner, a cylinder shall be rendered unserviceable in accordance with EN 12816, so that it cannot be re-issued into service as a pressure vessel. NOTE In some countries, render unserviceable means scrapping.

The size of this defect is recorded.
If the defects of the cylinders are different sizes, the size of the smaller defect shall be recorded;  two cylinders shall be submitted to the burst test as described in EN 14140 and two cylinders shall be submitted to the fatigue test as described in EN 14140;  if the cylinders pass the tests, the defect is acceptable.
The rejection limit can then be defined by the size of that defect;  when all rejection criteria have been established for a design of cylinder as defined in EN 14140, Table 1 and Table 2 sha
