BS EN 12285-1:2003 Workshop fabricated steel tanks - Horizontal cylindrical single skin and double skin tanks for the underground storage of flammable and non-flammable water polluting liquids
This standard specifies the requirements for shop fabricated cylindrical, horizontal steel tanks, single and double skin for the underground storage of water polluting liquids (both flammable and non-flammable) 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 and,
— for liquids with a maximum density of up to 1,9 kg/I and,
— with an operating pressure (po) of maximum 1,5 bar (abs.) and,
— for double skin tanks with a vacuum leak detection system where the kinematic viscosity does not exceed 5×10m/s.
This standard is applicable for normal operating temperature conditions (-20 ℃ to +50 ℃). Where temperatures are outside this range, additional requirements should be taken into account.
For guidance on the liquid-material combinations see Annex B.
This standard is not applicable to the liquid classes listed in Table 1 because of special dangers involved. This standard does not deal with internal coating.
The classifications referred to are those adopted by the United Nations Committee of Experts on the Transport of Dangerous Goods (not to be interpreted as tank classes described in 3.4).
