1 Scope This European Standard deals with welded steel transportable pressure drums intended for compressed and liquefied gases under pressure of water capacity from 150 litres up to 1 000 litres. This European Standard specifies the requirements for periodic inspection and testing to verify the integrity of such pressure drums to be re-introduced into service for a further period of time. It also defines a procedure to qualify existing pressure drums for free movement between member states of the European Union (see Annex A). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 14208, Transportable gas cylinders — Specification for welded pressure drums up to 1 000 litre capacity for the transport of gases — Design and construction EN ISO 11114-1, Transportable gas cylinders — Compatibility of cylinder and valve materials with gas contents — Part 1: Metallic materials (ISO 11114-1:1997) EN ISO 11114-2, Transportable gas cylinders — Compatibility of cylinder and valve materials with gas contents — Part 2: Non-metallic materials (ISO 11114-2:2000) EN ISO 11621, Gas cylinders — Procedures for change of gas service (ISO 11621:1997) EN ISO 13341, Transportable gas cylinders — Fitting of valves to gas cylinders (ISO 13341:1997) EN ISO 13769, Gas cylinders — Stamp marking (ISO 13769:2002) 3 Intervals between periodic inspection and test In order to ensure continued safe operation, pressure drums shall be subjected periodically to inspection and test in accordance with Annex B. A pressure drum shall fall due for periodic inspection and test on its first receipt by filler after expiry of the interval in Annex B. NOTE 1 Table B.1 gives a list of the intervals between periodic inspections for some gases which conforms to the current RID/ADR regulations and also gives recommendations which can be subsequently adopted by the RID/ADR regulations. Provided that the pressure drum has been subjected to normal conditions of use and has not been subjected to abusive and abnormal conditions making the pressure drum unsafe, there is no requirement for the user to return a pressure drum before the contents have been used even though the test interval may have been exceeded. However, it is suggested that pressure drums are re-tested at a period not exceeding twice the normative time interval specified in Table B.1. NOTE 2 Certain products such as hydrogen fluoride require an intermediate check of wall thickness as well as the contents to be checked for pressure rise due to the generation of gases such as hydrogen. Other products such as hydrogen bromide should not be allowed to exceed one and a half times the time interval for the normative test interval in Table B.1.
