The filling factor varies in different containers; what value is generally appropriate? Which new standards specify the filling coefficient values, and what are the specific regulations? Drawing on other older standards: SH3007-1999 stipulates that 1) for fixed-roof tanks and internal floating-roof tanks, a) if the tank volume is 1000 m3 or more, a value of 0.90 should be used; b) if the tank volume is less than 1000 m3, a value of 0.85 should be used. 2) For floating-roof tanks, a value of 0.90 should be used. 3) For spherical tanks and horizontal tanks, a value of 0.90 is generally appropriate. The old regulations state that for fixed pressure vessels containing liquefied gases, the filling coefficient is usually set at 0.9; for vessels whose volume has been measured actually, a value higher than 0.9 can be used, but it must not exceed 0.95 ； The filling coefficient can be adjusted appropriately according to the properties of the medium; for example, for lethal or flammable and explosive media, it is safer to use a lower filling coefficient! For example: 0.8
