If the material has a flash point at or above 38 °C (100 °F) and below 93 °C (200 °F), then the bulk packaging requirements of § 173.241 of this subchapter are applicable. If the material has a flash point of less than 38 °C (100 °F), then the bulk packaging requirements of § 173.242 of this subchapter are applicable.
<sub>Authorized IBCs:</sub> Metal (31A, 31B and 31N); Rigid plastics (31H1 and 31H2); Composite (31HZ1).<br><sub>Additional Requirement:</sub> Only liquids with a vapor pressure less than or equal to 110 kPa at 50 °C (1.1 bar at 122 °F), or 130 kPa at 55 °C (1.3 bar at 131 °F) are authorized.
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.
(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.
