| Nosaukums | This standard 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) at normal ambient temperature conditions (-20 °C to +50 °C) 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 1,9 kg/l 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 10-3 m2/s. Tanks designed to this standard allow for an earth cover of 1.5m and for the tank to withstand traffic loads from a properly constructed roadway This standard is not applicable for the storage of liquids having dangerous good classes listed in Table 1 because of the special dangers involved. |
