This standard 22/30441056 DC BS EN 12285-4. Workshop fabricated steel tanks is classified in these ICS categories:
  • 13.300 Protection against dangerous goods
  • 23.020.10 Stationary containers and tanks
This document specifies the requirements for metallic shop fabricated cylindrical vertical steel tanks, single and double skin for the aboveground storage of water polluting liquids (both flammable and non-flammable) within the following limits: — from Ø 1250 mm up to Ø 4 000 mm inner tank nominal diameter, and — up to maximum overall shell length of 6 times the nominal inner tank diameter (or max 14 m shell lenght Lz), and — tank possible to be divided from 1 to 5 compartments, — for liquids with maximum density of up to 1,9 kg/l, and — with an operating pressure (P0) of maximum 50kPa (0,5 bar (g)) and minimum – 5 kPa (- 50 mbar (g)), and — where double skin tanks with vacuum leak detection system are used the kinematic viscosity of the stored media shall not exceed 5 × 10−3 m2/s. This document is applicable for normal ambient temperature conditions (−40 °C to + 50 °C). Where temperatures are outside this range, additional requirements need to be taken into account. This document is not applicable to tanks used for storage and/or supply of fuel/gas for building heating/cooling systems, and of hot or cold water not intended for human consumption, nor to loads and special measures necessary in areas subject to risk of earthquakes. This document is not applicable for the storage of liquids having dangerous goods classes listed in Table 1 because of the special dangers involved. Table 1 - List of dangerous goods which are not covered by this document UN-classification Type of dangerous goods Class 1 Explosives Class 4.2 Substances liable to spontaneous combustion Class 4.3 Substances which in contact with water emit flammable gases Class 5.2 Organic peroxides Class 6.2 Infectious substances Class 7 Radioactive substances, hydrocyanic or hydrocyanic solvent liquids, metal carbons, hydrofluoric acid, bromide liquids NOTE 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 6.2).
