This European Standard gives requirements for the design, fabrication, inspection, testing and verification of GRP tanks and vessels with or without Thermoplastics lining for storage or processing of fluids, factory made or site built, non pressurised or pressurised up to 10 bar, for use above ground.
The terms vessels and tanks as used in this European Standard include branches up to the point of connection to pipe work or other equipment by bolting and supports, brackets or other attachments bonded directly to the shell. In addition to the definitive requirements, this European Standard also requires the items in Clause 5 to be fully documented.
This European Standard covers vessels and tanks subject to temperatures between – 40 °C and + 120 °C.
NOTE It is possible that future advances in resin technology would allow tanks and vessels to be considered for operating temperatures above + 120 °C. Should such a situation arise and a manufacturer wishes to take advantage of such developments, then all other requirements of the standard shall be maintained and such tanks and vessels shall only be designed in accordance with the advanced design method given in 7.8.3.
Excluded from this European Standard are:
-- tanks and vessels for the transport of fluids;
-- underground storage tanks;
-- spherical vessels;
-- vessels and tanks of irregular shape;
-- tanks and vessels with double containment;
-- tanks and vessels which are subject to the risk of explosion, or failure of which may cause an emission of radioactivity;
-- specification for fibre reinforced cisterns of one piece and sectional construction for the storage, above ground, of cold water (see EN 13280:2001).
