intended for the transport of refrigerated liquefied gases
6.7.4.1 Definitions
Copyright@United Nations, 2011. All rights reserved.
For the purposes of this section:
Holding time means the time that will elapse from the establishment of the initial filling condition until the
pressure has risen due to heat influx to the lowest set pressure of the pressure limiting device(s);
Jacket means the outer insulation cover or cladding which may be part of the insulation system;
Leakproofness test means a test using gas subjecting the shell and its service equipment, to an effective
internal pressure not less than 90% of the MAWP;
Maximum allowable working pressure (MAWP) means the maximum effective gauge pressure permissible at
the top of the shell of a loaded portable tank in its operating position including the highest effective pressure
during filling and discharge;
Maximum permissible gross mass (MPGM) means the sum of the tare mass of the portable tank and the
heaviest load authorized for transport;
Minimum design temperature means the temperature which is used for the design and construction of the
shell not higher than the lowest (coldest) temperature (service temperature) of the contents during normal
conditions of filling, discharge and transport;
Portable tank means a thermally insulated multimodal tank having a capacity of more than 450 litres fitted
with service equipment and structural equipment necessary for the transport of refrigerated liquefied gases.
The portable tank shall be capable of being filled and discharged without the removal of its structural
equipment. It shall possess stabilizing members external to the tank, and shall be capable of being lifted
when full. It shall be designed primarily to be loaded onto a transport vehicle or ship and shall be equipped
with skids, mountings or accessories to facilitate mechanical handling. Road tank-vehicles, rail tankwagons,
non-metallic tanks, intermediate bulk containers (IBCs), gas cylinders and large receptacles are not
considered to fall within the definition for portable tanks;
Reference steel means a steel with a tensile strength of 370 N/mm 2 and an elongation at fracture of 27%;
Shell means the part of the portable tank which retains the refrigerated liquefied gas intended for transport,
including openings and their closures, but does not include service equipment or external structural
equipment;
