Annex A (informative) A-deviations

Establishes rules for the design and calculation of welded static, vertical, non-pressurized, cylindrical, flat-bottom thermoplastic tanks. Applicable to tanks fabricated in the following thermoplastics. Polyethylene (PE), Polypropylene (PP) Poly (vinyl chloride) (PVC) Poly (vinylidene fluoride) (PVDF). Does not take into account wind and/or snow loading. If wind or/and snow loading has to be taken into account additional calculations are necessary. Applicable to tanks in which the cylindrical shell is made of welded plates or a wound cylinder or an extruded pipe. Short-term and long-term active pressures as well as the hydrostatic loading are taken into account in the calculation.
