EEMUA 225 : 2017

This Publication is aimed at owners and operators of above-ground plastic tanks, which are typically cylindrical in shape. The document’s content is aimed mainly at tanks being operated at atmospheric pressure or at pressures above the liquid head up to 0.5 barg. It is not therefore intended for tanks which would be classed as pressure vessels under the Pressure Equipment Directive (PED), although some of its content may still be relevant and useful to users operating plastic pressure vessels in what are usually quite specific applications. The publication covers a range of topics, from how to specify the design, through inspection, maintenance, and repair, to decisions at end-of-life and safe disposal.
