multi-modal applicability. PHMSA is adding the following defined terms:
Aircraft battery: This term means a battery designed in accordance with a recognized
aircraft battery design standard (e.g. FAA technical standard order) that is capable of
meeting all aircraft airworthiness requirements and operating regulations.
Currently the HMR does not define aircraft battery. The recent amendment of
special provision A51 in the ICAO TI require PHMSA to define this term to ensure
appropriate application of this special provision.
Flexible Bulk Container (FBC): This term means a flexible container with a capacity not
exceeding 15 cubic meters and includes liners and attached handling devices and service
equipment.
Currently the HMR do not prescribe requirements for the transport of FBCs. In this
final rule, PHMSA is adopting various transportation and manufacturing requirements for
FBCs. Prior to adoption of such standards, the term “Flexible Bulk Container” must be
defined. Therefore we are adopting the above definition of an FBC based on the definition
for FBC adopted in the IMDG Code and 17 th Revised Edition of the UN Model
Regulations.
