| B14 | Each bulk packaging, except a tank car or a multi-unit-tank car tank, must be insulated with an insulating material so that the overall thermal conductance at 15.5 °C (60 °F) is no more than 1.5333 kilojoules per hour per square meter per degree Celsius (0.075 Btu per hour per square foot per degree Fahrenheit) temperature differential. Insulating materials must not promote corrosion to steel when wet. Browse special provision B14 |

| B32 | MC 312, MC 330, MC 331, DOT 412 cargo tanks and DOT 51 portable tanks must be made of stainless steel, except that steel other than stainless steel may be used in accordance with the provisions of §173.24b(b) of this subchapter. Thickness of stainless steel for tank shell and heads for cargo tanks and portable tanks must be the greater of 6.35 mm (0.250 inch) or the thickness required for a tank with a design pressure at least equal to 1.3 times the vapor pressure of the lading at 46 °C (115 °F). In addition, MC 312 and DOT 412 cargo tank motor vehicles must: - a. Be ASME Code (U) stamped for 100% radiography of all pressure-retaining welds;
- b. Have accident damage protection which conforms with §178.345-8 of this subchapter;
- c. Have a MAWP or design pressure of at least 87 psig; and
- d. Have a bolted manway cover.

| TP2 | a. The maximum degree of filling must not exceed the degree of filling determined by the following:  Where: t r is the maximum mean bulk temperature during transport, t f is the temperature in degrees celsius of the liquid during filling, and α is the mean coefficient of cubical expansion of the liquid between the mean temperature of the liquid during filling (t f) and the maximum mean bulk temperature during transportation (t r) both in degrees celsius. b. For liquids transported under ambient conditions α may be calculated using the formula:  Where: d 15 and d 50 are the densities (in units of mass per unit volume) of the liquid at 15 °C (59 °F) and 50 °C (122 °F), respectively.
