21、SI EN 12285-1:2003 (E) 3 Foreword This document (EN 12285-1:2003) has been prepared by Technical Committee CEN /TC 221 “Shop fabricated metallic tanks and equipment for storage tanks and for service stations“, the secretariat of which is held by DIN. This European Standard shall be given the status
22、of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2003, and conflicting national standards shall be withdrawn at the latest by September 2003. This standard is part of a series of standards in the field of shop fabricated metallic tanks.
23、 The titles of the standards which are already edited or are under preparation are: Workshop fabricated steel tanks; Horizontal cylindrical single skin and double skin tanks for the underground storage of flammable and non-flammable water polluting liquids Workshop fabricated steel tanks; Horizontal
24、 cylindrical single skin and double skin tanks for the aboveground storage of flammable and non-flammable water polluting liquids. Further standards will be evaluated according to former decisions of CEN/TC 221 and according to the common rules for standard works for CEN-standards. Annexes A, B and
25、C are informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembou

27、ricated 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 an
28、d, 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 x 10-3 m2/s. This standard is applicable for normal operating temperat
29、ure conditions (-20 C to +50 C). 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.
30、 This standard does not deal with internal coating.
