— welded and brazed steel LPG cylinders with a specified minimum wall thickness (see EN 1442 and EN 12807 [1] or an equivalent standard); — welded steel LPG cylinders without specified minimum wall thickness (see EN 14140 or an equivalent standard); — welded aluminium LPG cylinders (see EN 13110 [2] or an equivalent standard); — composite LPG cylinders (see EN 14427 or an equivalent standard); and — over-moulded cylinders (OMC). Specific requirements for the different types of cylinders are detailed in Annex A, Annex B, Annex C, Annex D and Annex G. This draft standard is intended to be applied to cylinders complying with RID/ADR [6] [7] (including pi marked cylinders) and also to existing non RID/ADR cylinder populations. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

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, 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. Table A.2 — Corrosion on the cylinder wall Type of corrosion Description Rejection limit Isolated corrosion pits A pitting of metal occurring in isolated areas at a concentration not greater than 1 pit per 500 mm2 of surface area. When the depth of discrete pits exceeds 0,6 mm. A greater depth of corrosion can be accepted provided that depth of corrosion does not reduce the wall thickness below the minimum calculated wall thickness. SIST EN 1439:2018
