39、drical, 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) and installed in industrial processes or in petrol stations at normal ambient temperature conditions (20 C to +50 C)

40、within the following limits: from 800 mm up to 3 000 mm nominal diameter and; up to a maximum overall length of 6 times the nominal diameter; with an operating pressure (Po) of maximum 50 kPa (0,5 bar(g) and minimum 5 kPa (50 mbar(g) and; for double skin tanks with a vacuum leak detection system whe

41、re the kinematic viscosity does not exceed 5 103m2/s. Tanks designed to this standard allow for an earth cover of up to 1,5 m. If there are imposed traffic loads or a greater earth cover, calculation is expected to be carried out. This document is not applicable to tanks used for storage and/or supp

42、ly 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. Guidance on installation of tanks is presented in Annex A, which does not include special measures th

43、at might be necessary in areas subject to flooding. This document is not applicable for the storage of liquids having dangerous goods classes listed in Table 1 because of the special dangers involved.
