3 Terms and definitions For the purpose of this European Standard, the following terms and definitions apply. 3.1 competent body person or corporate body defined by the national authority, which by a combination of appropriate qualification, training, experience and resources is able to make objective judgements on the subject 3.2 competent person person who by a combination of training, experience and supervision is able to make objective judgements on the subject 3.3 periodic inspection activities carried out at defined intervals, such as examining, measuring, testing or gauging the characteristics of a cylinder and comparing these with specified requirements as defined in EN 14427 and marking to attest conformity 3.4 LPG (liquefied petroleum gas) mixture of predominantly butane or propane with traces of other hydrocarbon gases classified in accordance with UN number 1965, hydrocarbon gases mixture, liquefied, NOS or UN number 1075, petroleum gases, liquefied NOTE In some countries, UN number 1011, 1978 may also be designated LPG. 3.5 tare weight sum of the mass of the empty cylinder, the mass of the valve including a dip tube where fitted, and the mass of all other parts that are permanently attached to the cylinder when it is being filled, e.g. fixed valve guard 3.6 casing permanently attached sleeve covering part of or the whole of the pressure containing envelope usually incorporating a foot ring and a shroud NOTE Permanently attached means that the casing cannot be removed during service without being destroyed, or by using special tools.

For transparent composite cylinders, the internal visual inspection may be made from outside. Periodic inspections/tests shall be carried out under the responsibility of a body approved by a competent authority. 5.2 External visual inspection 5.2.1 Preparation If required the cylinder shall be cleaned and have all labels, tar oil or other foreign matter removed from its external surface e.g. by water jet cleaning, chemical cleaning or other suitable methods. Care shall be taken to avoid damaging the cylinder. Cylinders rejected shall be segregated for rendering unserviceable. NOTE In some countries, render unserviceable means scrapping. 5.2.2 Inspection procedure The entire surface of the cylinder shall be inspected for: a) Cuts, gouges, bulges, cracks or de-laminations, applying the criteria for acceptance/rejection in 5.2.3. b) Other defects e.g. depressed bung or fire damage applying to the criteria for acceptance/rejection in
Table 1. c) Integrity of all permanent attachments. d) The integrity of the mandatory permanent marking. Any cylinder rejected by the competent person shall be segregated for scrapping. 5.2.3 Visible defects The owner (or his authorized representative) shall provide to the filler acceptance/rejection criteria for physical and material defects and heat damage on the cylinder/casing.

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 (see EN 14427:2004, 5.2.5) and two cylinders shall be submitted to the pressure cycle test (see EN 14427:2004, 5.2.6);  if the cylinders pass the tests, the defect is acceptable.
The rejection limit can be defined by the size of that defect;  when all rejection criteria have been established for a design of cylinder as defined in EN 14427:2004, A.2.1, Table 1 shall be completed by the owner/manufacturer of the cylinder.
Annex B shows an example of a completed table.

Abrasion damage caused by wearing, grinding or rubbing material away by friction. Cuts or gouges caused by contact with sharp objects in such a way as to cut into the composite, reducing its thickness at that point. See 5.2.3 De-lamination and
impact damage Inter-laminar de-lamination where there is a separation of layers of stran
