19、876:2007 (E) 5 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
20、 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 docu
