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. The main changes between this version of the standard and the 2005 version is that this version combines EN 1439:2005, EN 14763:2005, EN 14794:2005 and EN 14913:2005 into a single standard. This European Standard supersedes EN 1439:2005, EN 14763:2005, EN 14794:2005 and EN 14913:2005. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

NOTE
This is not a composite cylinder; see EN 14427 and Figure G.1 3.6 casing permanently attached sleeve covering part of or the whole of the pressure containing envelope of a composite cylinder, usually incorporating a foot ring and a shroud NOTE Permanently attached means that casing cannot be removed during service without destruction, or by using special tools. 3.7 filling ratio ratio of the mass of gas introduced into a cylinder to the mass of water at 15 °C that would fill the same cylinder fitted ready for use NOTE See Annex E for filling ratios. 3.8 reference temperature temperature used for the calculation of safe filling quantity NOTE See Annex E for reference temperatures. 3.9 filled to a level filled to a fixed level using a fixed liquid level device

establishment where filling and checking of LPG cylinders takes place 3.13 reconditioning major repairs to cylinders, which can include hot work, welding or de-denting carried out by specialists away from potential sources of flammable air/gas mixture 3.14 periodic inspection activities carried out at defined intervals, such as examining, measuring, testing or gauging the characteristics of a cylinder, comparing these with specified requirements as defined in EN 1440 and marking to attest conformity 3.15 tare mass 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 4 Segregation of cylinders prior to filling 4.1 General Cylinders shall be checked and segregated into the categories specified in 4.2 to 4.4. A flow diagram of the checks before, during and after filling is given in Annex F. 4.2 Cylinders suitable for filling The cylinder shall be deemed suitable for filling if the following conditions apply: a) design code/specification is identifiable; b) tare indication and water capacity are known or marked; c) allowed quantity and identification of the product (butane, propane or mixtures thereof, the properties of which were considered for the design of the cylinder) are indicated; d) cylinder is within the test date as determined from the marked manufacture date or periodic inspection date; e) cylinder does not have defects as described in 4.4.
For metallic cylinders, the inspection of the foot-ring for corrosion or damage shall determine the need for a more thorough external visual examination of the cylinder base; f) cylinder is fitted with a pressure relief valve, if required by the manufacturing standard.

Cylinders leaking through the body shall be disposed of in accordance with EN 12816 (where applicable).
Leaking or damaged valves shall be repaired or replaced. Valves can be removed and refitted safely from and to a pressurized LPG cylinder, provided the facility includes dedicated equipment.
This equipment shall be operated only by competent personnel working in accordance with a written procedure. Rejection limits for physical, material and other defects on the cylinder shell are given in Annex A, Annex B, Annex C and Annex D. NOTE Rejection limits for a particular type of protected cylinder are given in Annex G 6 Filling conditions 6.1 Safe filling quantity Cylinders shall not be filled in excess of the safe filling quantity.
The safe filling quantity is determined from the safe filling ratio agreed by the relevant national competent authorities in accordance with Annex E.
6.2 Safe filling mixture and quality Cylinders shall be filled with the appropriate mixture and quality of LPG, as specified in EN 13952.

When cylinders are filled to a level, the fixed liquid level device shall be checked for operability.
7 Post filling checks 7.1 Check of filled amount Each cylinder shall be checked to ensure that the maximum mass has not been exceeded, either by check weighing within the tolerances as determined by the relevant national competent authorities or by a determination of the ullage space remaining.
Where accepted by the relevant national competent authorities, other systems of checking, such as sample weighing or statistical-data application, may be used when the filling mass is controlled automatically. 7.2 Action necessary for over / under-filled cylinders If the cylinder is over-filled, the excess LPG shall be removed as soon as reasonably practical and the cylinder re-checked. If the cylinder is under-filled, the appropriate amount of LPG shall be added and the cylinder re-checked. 7.3 Final checks Cylinders, valves and valve seals shall be checked for leakage.
Leaks shall be dealt with in accordance with the procedures in Clause 5. Cylinders shall be checked prior to despatch or storage, for the correct fitting of valve caps or plugs, valve protection caps/guards and labelling if required.

Specific requirements for welded and brazed steel LPG cylinders Rejection limits for physical, material and other defects on the cylinder shell are given in Table A.1, Table A.2 and Table A.3.
Table A.1 — Physical defects in the cylinder wall Defect Description Rejection limit Bulge Visible swelling of the cylinder All
Dent A depression in the cylinder that has neither penetrated nor removed metal, when its width at any point is greater than 2 % of the external cylinder diameter. When the depth of the dent exceeds 25 % of its width at any point a. Cut or gouge A sharp impression where metal has been removed or redistributed. Where the original calculated wall thickness is known:
depth of cut or gouge is such that the
undamaged (remaining) wall is less than the
minimum calculated wall thickness. Where the original calculated wall thickness is not known:
all. Dent containing cut or gouge A depression in the cylinder within which there is a cut or gouge. When the size of the dent or cut or gouge exceeds the dimensions for rejection as an individual defect. Crack A split or rift in the cylinder shell. All Lamination Layering of the material within the cylinder wall appearing as a discontinuity, crack, lap or bulge at the surface. All a Appearance (e.g. sharp dent) and location (e.g. on shoulder of the cylinder) also play a part in the evaluation of dent severity.

A greater depth can be accepted providing that the depth of corrosion does not reduce the wall thickness below the minimum calculated wall thickness. Chain pitting or line or channel corrosion A series of pits or corroded cavities of limited width along the length or around the cylinder circumference. 1) When the total length of corrosion in any direction exceeds 50 % of the circumference of the cylinder; or 2) When the depth of penetration exceeds 0,4 mm. A greater depth can be accepted providing that the depth of corrosion does not reduce the wall thickness below the minimum calculated wall thickness; or
3) When the depth of corrosion cannot be measured. Crevice corrosion Crevice corrosion occurs in the area of the intersection of the foot-ring or shroud with the cylinder. When the depth of penetration exceeds 0,4 mm or when the depth of corrosion cannot be measured. Table A.3 — Other defects
Defect Description Rejection limit Depressed bung Damage to the bung which has altered the profile of the cylinder. A limited level of depression/alignment deviation, as agreed by the competent body. Otherwise, all Arc or torch burns Burning of the
