EN 12285-3:2019 Workshop fabricated steel tanks - Part 3: Horizontal cylindrical single skin and double skin tanks for the underground storage of f lammable and nonflammable water polluting liquids for heating and cooling of buildings
This document specifies the product characteristics and test/assessment methods for workshop fabricated cylindrical@ horizontal steel tanks@ single (type S) and double skin (type D) intended to be used for the underground storage of water polluting liquids (both flammable and non-flammable)@ specifically used for storage and/or supply of fuel for building heating/cooling systems@ and of hot or cold water not intended for human consumption at normal ambient temperature conditions (?20 ??to +50 ?? within the following limits: ?? from 800 mm up to 3000 mm nominal diameter and; ?? up to a maximum overall length of 6 times the nominal diameter; ?? for liquids with a maximum density of up to 1@1 kg/l and; ?? with an operating pressure (Po) of maximum 50 kPa (0@5 bar(g)) and minimum ?C 5 kPa (?C50 mbar(g)) and; ?? for double skin tanks with a vacuum leak detection system where the kinematic viscosity does not exceed 5 ?? 10?3 m2/s. Two tank types are distinguished: ?? Type S: Single skin; ?? Type D: Double skin. Tanks designed to this document allow for an earth cover of up to 1@5 m. If there are imposed traffic loads or a greater earth cover@ calculation will occur. This document is not applicable to tanks installed in industrial processes or in petrol stations@ nor to loads and special measures necessary in areas subject to risk of earthquakes and/or to flooding.
