EN 14795:2005 (E) 3 Foreword This European Standard (EN 14795:2005) 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of an identical text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the latest by May 2006.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 the present standard are normative only when the standards themselves are referred to in the RID and/or in the technical annexes of the ADR. 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 14795:2005 (E) 4 Introduction The primary objective of the periodic inspection of transportable refillable welded aluminium liquefied petroleum gas (LPG) cylinders is that, at the completion of the test, the cylinders can be re-introduced into service for a further period of time. The very large populations of LPG cylinders in use have led to the development of alternative methods of inspection.
Periodic inspection is normally carried out at a test station operated under the responsibility of a competent gas organisation, or of a third party. The specification has now been prepared to reflect the current state of the art for periodically inspecting LPG cylinders, and is based upon the operating experience of millions of cylinder years of service over a period of more than 50 years. 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.

(see EN 13110). This 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.

3 Terms and definitions For the purposes 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 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 and marking to attest conformity

hydraulic test (see 5.4.2), pneumatic proof and leak test (see 5.4.3) 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. 5.2 External visual inspection 5.2.1 Preparation for external visual inspection a) If required, the cylinder shall be cleaned and have all tar, oil, labels or other foreign matter removed from
