EN 14767:2005 (E) 3 Foreword This European Standard (EN 14767:2005) has been prepared by Technical Committee CEN/TC 286 “Liquefied petroleum gas equipment and accessories”, the secretariat of which is held by NSAI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006. This European Standard has been submitted for reference into the RID and/or in the technical annexes of the ADR. Therefore the standards listed in the normative references and covering basic requirements of the RID/ADR not addressed within this European Standard are normative only when the standards themselves are referred to in the RID and/or in the technical annexes of the ADR. Photographs presented in Annex B should be considered in colour in order to improve pictorial guidance. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
EN 14767:2005 (E) 4 Introduction The primary objective of the periodic inspection of transportable refillable composite liquefied petroleum gas (LPG) cylinders is that, at the completion of the tests, the cylinders can be re-introduced into service for a further period of time. Periodic inspection is normally carried out at a test station operated under the responsibility of a competent gas organisation, or of a third party. This European Standard has now been prepared to reflect the current state of the art for periodically inspecting composite LPG cylinders. 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 periodic inspection intervals, procedures for inspection, inspection and testing for transportable refillable composite LPG cylinders with a water capacity from 0,5 l up to and including 150 l. This European Standard is applicable to cylinders that comprise a liner of metallic material (welded or seamless), or non-metallic material, (or a mixture thereof), reinforced by a wound composite consisting of fibres of glass or carbon or aramid (or a mixture thereof) embedded in a matrix. This European Standard is also applicable to composite cylinders without liners. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

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.
EN 14767:2005 (E) 6 4 Written scheme of inspection The determination of the interval between periodic inspections shall be dependent on the content of a written scheme that shall be approved by a competent authority as complying with the conditions outlined in Annex A. NOTE The interval between periodic inspections shall be 5 years. Nevertheless, a longer interval may be agreed provided the requirements of Annex A are fully 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, an internal visual inspection as described in 5.3, and additionally, at least one of the procedures listed in 5.4.
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.
EN 14767:2005 (E) 7 Those criteria shall be at least those established by the manufacturer taking into account the design conditions of the cylinder type (e.g.: nature of the casing if any, nature and type of the fibre and of the resin system). Rejection criteria for defects on cylinders are described in Table 1. For rejection criteria described in Table 1, if applicable, the limit shall be defined in accordance with the following method: for each type of cylinder as defined in EN 14427:2004, A.2.1, the manufacturer shall provide samples; for each rejection criteria, the manufacturer shall provide at least 4 cylinders with the same defect.
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.
EN 14767:2005 (E) 8 Table 1 —Acceptance/Rejection criteria Defect Description Rejection limit Abrasion damage or damage from cuts
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
