This European Standard shall be given the status o
30、f a national standard, either by publication of an identical text or by endorsement, at the latest by January 2019, and conflicting national standards shall be withdrawn at the latest by April 2020. Attention is drawn to the possibility that some of the elements of this document may be the subject o
31、f patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document, together with prEN 12285-3:2016, supersedes EN 12285-1:2003. Compared to EN 12285-1:2003, this document has been revised as follows: exclusion of tanks covered by the Mandate M/131; old C
32、lause 3, Terms and definitions has been combined with old Clause 4, Symbols and abbreviations; old Clause 5, Designation and purchasers specification has been combined with new Clause 7, Classification and designation; old Clause 6, Materials, Clause 7, Design, Clause 8, Fabrication and Clause 10, H
33、andling and installation have been replaced by new Clause 4, Product characteristics; old Clause 9, Testing has now become Clause 5, Testing, assessment and sampling methods; old Clause 11, Marking of the tank and manufacturers statement has now been combined with new Clause 8, Marking, labelling an
34、d packaging. The informative Annexes A and B give further guidance: A on transport, storage and installation procedures and B on the liquid-material combinations to be chosen. Annex C provides guidance on environmental aspects. This European Standard Workshop fabricated steel tanks consists of 3 par
35、ts: Part 1: Horizontal cylindrical single skin and double skin tanks for the underground storage of flammable and nonflammable water polluting liquids other than for heating and cooling of buildings; Part 2: Horizontal cylindrical single skin and double skin tanks for the aboveground storage of flam
36、mable and non-flammable water polluting liquids; Part 3: Horizontal cylindrical single skin and double skin tanks for the underground storage of flammable and nonflammable water polluting liquids for heating and cooling of buildings. According to the CEN-CENELEC Internal Regulations, the national st
37、andards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

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.

44、ngerous 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 c
45、arbons, 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).
