EN 1440:2008 (E) 5 Introduction The primary objective of the periodic inspection of transportable refillable 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. The very large populations of traditional steel LPG cylinders in use have led to the development of alternative methods of inspection. This European Standard has now been prepared to reflect the current state of the art for period inspecting of LPG cylinders, and is based on the operating experience of many hundreds of millions of cylinder years of service. 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. This standard is a combination of EN 1440:2005, with EN 14767:2005, EN 14795:2005 and EN 14914:2005. SIST EN 1440:2008
EN 1440:2008 (E) 6 1 Scope This European Standard specifies procedures for periodic inspection and testing, for transportable refillable LPG cylinders with a water capacity from 0,5 l up to and including 150 l.

If the cleaning method involves the wetting of the outside surface, the outside surface shall be completely dried before commencing the test procedure.
5.3.2.3 Test equipment Pressure gauges that are used to read the cylinder test pressure shall be in accordance with EN 837-1 and EN 837-3 accuracy class 1,6 or better.
They shall be calibrated or checked for accuracy against a master gauge at regular intervals and in any case not less frequently than once a month.
The master gauge shall be re-calibrated in accordance with national requirements.
The design and installation of the equipment and the cylinders connected to it shall ensure that no air is trapped in the system. All joints within the system shall be leak tight. A device shall be fitted to the test equipment to ensure that no cylinder is subjected to pressure in excess of its test pressure by more than the tolerance given in 5.3.2.4. The test equipment shall not restrict the expansion of the cylinder. 5.3.2.4 Procedure a) Cylinder shall be positioned so that the welds are visible during the test. b) Pressure of the test shall be at least the test pressure marked on the cylinder. c) Pressure shall be increased gradually in the cylinder until the test pressure is reached.
Then the cylinder shall be isolated from the pumping system. d) Test pressure shall not be exceeded by more than 20 % or 6 bar, whichever is the least.
More than one cylinder may be tested at a time provided they all have a test pressure within the tolerance specified.
If SIST EN 1440:2008
EN 1440:2008 (E) 11 the cylinder is tested to a higher pressure than that marked, a competent person shall check that the actual pressure applied does not result in a general membrane stress in the cylinder wall exceeding 95 % of the guaranteed minimum yield strength of the material used in the finished cylinder. e) Test pressure shall be held for the time necessary to inspect the cylinder and check it out for any leak and/or other defects, but not less than 15 s. f) If there is leakage in the pressure system, it shall be corrected and the cylinders re-tested. g) Cylinders, that do not leak or show any visible permanent distortion after the pressure has been released, shall be deemed to have passed this test.
Cylinders, showing visible defects, shall be examined by a competent person. h) Cylinders that fail shall be rejected.
NOTE If a cylinder leaks through a pinhole at the weld, it should be examined by a competent person to determine whether it can be repaired by welding or rendered unserviceable.
Welding or repairing should be carried out in accordance with the manufacturer’s requirements.
These types of repairs are not permitted by the ADR. 5.3.3 Internal visual inspection 5.3.3.1 Internal visual inspection for welded and brazed steel LPG cylinders and LPG cylinders of alternative design and construction 5.3.3.1.1 General Internal visual inspection is applicable to cylinders where the wall thickness is equal to or greater than the minimum calculated wall thickness and the design burst pressure is known, or can be shown to be at least: 35 bar for commercial butane cylinders, and
