mentioned in clause 4 without suchdeformation which could affect safety and which could lead to leakage.This requirement can be validated by:?the calculation;?the calculation and pressure strengthening method(see EN 14398-2);?the calculation and experimental method.The mechanical loads to be considered are given in 5.2 and 5.3.5.2 Load during the pressure testThe load exerted during the pressure test is spp3,1t?where?tp=test pressure(in bar);?sp=allowable working pressure(=relief device set pressure)(in bar).5.3 Other mechanical loads during normal operation5.3.1 The following loads shall be considered to act in combination where relevant:?a pressure equal to the maximum allowable working pressure in the inner vessel and pipework;?the pressure exerted by the liquid column when filled to capacity;?loads produced by the thermal movement of the inner vessel,outer jacket and interspace piping;?loads imposed in lifting and handling fixtures(at the vessel);?load due to dynamic effects,when the vessel is filled to capacity,giving consideration to:?the inner vessel support system including attachments to the inner vessel and outer jacket;?the interspace and external piping;?where applicable the outer jacket supports and the supporting frame.5.3.2 The following dynamic loads during normal operation shall be considered for the fastenings and the supportsystem of the inner vessel:?equal to twice the mass of the inner vessel when filled to the capacity shown on the data plate exerted by theinner vessel in the direction of travel and vertically downwards;?equal to the mass of the inner vessel when filled to the capacity shown on the data plate exerted by the innervessel at right angel to the direction of travel and vertically upwards;for tank-containers:equal to twice themass in each horizontal direction if the direction of travel is not clearly determined.Licensed Copy:sheffieldun sheffieldun,na,Tue Oct 31 01:55:12 GMT+00:00
