a. The maximum degree of filling must not exceed the degree of filling determined by the following:<br><br>Where: <br>t<sub>r</sub> is the maximum mean bulk temperature during transport, <br>t<sub>f</sub> is the temperature in degrees celsius of the liquid during filling, and <br>α is the mean coefficient of cubical expansion of the liquid between the mean temperature of the liquid during filling (t<sub>f</sub>) and the maximum mean bulk temperature during transportation (t<sub>r</sub>) both in degrees celsius. <br>b. For liquids transported under ambient conditions α may be calculated using the formula:<br><br>Where: <br>d<sub>15</sub> and d<sub>50</sub> are the densities (in units of mass per unit volume) of the liquid at 15 °C (59 °F) and 50 °C (122 °F), respectively.
A portable tank having a minimum test pressure of 4 bar (400 kPa) may be used provided the calculated test pressure is 4 bar or less based on the MAWP of the hazardous material, as defined in § 178.275 of this subchapter, where the test pressure is 1.5 times the MAWP.
(i) The material may be stowed “on deck” or “under deck” on a cargo vessel and on a passenger vessel carrying a number of passengers limited to not more than the larger of 25 passengers, or one passenger per each 3 m of overall vessel length; and
(ii) “On deck only” on passenger vessels in which the number of passengers specified in paragraph (k)(2)(i) of this section is exceeded.
