In accordance with the specification of the steel product standards, ReH may be replaced by Rp0,2.b
A higher value is accepted provided that Cr + Mo + Ni + Cu + V < 0,75 %.4.2 Pressure parts other than shells and endsMaterials for pressure parts other than shells and ends shall comply with the appropriate harmonised EuropeanStandard for the material or a similar specification, which has European materials approval, or particular materialapproval.SIST EN 14075:2003

Suitabilityof the chosen consumables shall be demonstrated in accordance with 7.6.3.4.5 CertificatesThe tank manufacturer shall obtain certificates showing the chemical analysis and details of the mechanicalproperties of the steel supplied for the construction of the pressure retaining parts of the tank. The certificates shallbe in accordance with EN 10204, certificate Type 3.1.B.4.6 Non metallic materials (gaskets)Non metallic materials shall be compatible with both phases of LPG over the full range of pressures andtemperatures anticipated in service.5 Design5.1 GeneralTank thicknesses shall be calculated in accordance with annex E.For tanks intended to contain LPG which complies with ISO 9162 supplied to a national or international standard orother equivalent specification, no internal corrosion allowance is required.For tanks protected against external corrosion in accordance with 10.1, no external corrosion allowance is required.The appropriate weld joint coefficient for the material used and the level of non-destructive testing to be adoptedshall be selected in accordance with Table 2.The tank shall be designed to withstand the forces of pressure, vacuum conditions, weight of the surroundingground in operating condition, anti flotation devices and liquid load in accordance with 5.3, 5.4 and 5.5.Where necessary, attachments to the tank shall be welded using a backing plate.A fully detailed, dimensional drawing shall be produced.SIST EN 14075:2003
