Scope

This document specifies the requirements for metallic shop fabricated cylindrical, horizontal steel tanks, single and double skin for the aboveground storage of water polluting liquids (both flammable and non-flammable) 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 and,
- 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,
- where double skin tanks with a vacuum leak detection system are used the cinematic viscosity of the stored media shall not exceed 5  10-3 m2/s.

This document is applicable for normal ambient temperature conditions (- 20 °C to + 50 °C). Where temperatures are outside this range, additional requirements need to be taken into account.
