Paragraph Index: 4676

(5) In no case shall pressure receptacles be filled in excess of the limit permitted in the following requirements: (a) For compressed gases, the working pressure shall be not more than two thirds of the test pressure of the pressure receptacles. Restrictions to this upper limit on working pressure are imposed by special packing provision "o". In no case shall the internal pressure at 65 °C exceed the test pressure. (b) For high pressure liquefied gases, the filling ratio shall be such that the settled pressure at 65 °C does not exceed the test pressure of the pressure receptacles. The use of test pressures and filling ratios other than those in the table is permitted provided that the above criterion is met, except where special packing provision "o" applies. For high pressure liquefied gases for which data is not provided in the table, the maximum filling ratio (FR) shall be determined as follows: h g P x d x x 5,8 FR − = where FR = maximum filling ratio dg = gas density (at 15 °C, 1 bar)(in kg/m3) Ph = minimum test pressure (in bar). If the density of the gas is unknown, the maximum filling ratio shall be determined as follows: x R x MM x P FR h − = where FR = maximum filling ratio Ph = minimum test pressure (in bar) MM = molecular mass (in g/mol) R = 8.31451 x 10-2 bar.l.mol-1.K-1 (gas constant). For gas mixtures, the average molecular mass is to be taken, taking into account the volumetric concentrations of the various components. (c) For low pressure liquefied gases, the maximum mass of contents per litre of water capacity shall equal 0.95 times the density of the liquid phase at 50 °C; in addition, the liquid phase shall not fill the pressure receptacle 2006/128. szám at any temperature up to 60 °C. The test pressure of the pressure receptacle shall be at least equal to the vapour pressure (absolute) of the liquid at 65 °C, minus 100 kPa (1 bar). For low pressure liquefied gases for which filling data is not provided in the table, the maximum filling ratio shall be determined as follows: ld x 0,24) - BP x (0,0032 FR = where FR = maximum filling ratio BP = boiling point (in Kelvin) dl = density of the liquid at boiling point (in kg/l). (d) For UN No. 1001 acetylene, dissolved, and UN No. 3374 acetylene, solvent free, see (10), special packing provision "p".
