Type C Packages The 1996 Edition of the IAEA Transport Regulations introduced a requirement for a more robustly designed package – the Type C Package – to transport the more highly radioactive material by air. Type C packages must satisfy all the additional requirements of Type A packages and most of the additional requirements of Type B packages. Type C packages are subjected to a series of tests to prove their ability to withstand transport incidents and accidents. This type of package has not yet been developed.

Type C Package Requirements
Criteria
Requirements
General requirements for all packages. Additional pressure and temperature requirements if transported by air, Type A additional requirements, Type B additional requirements (internal heat generation and maximum surface temperature). Each of the following tests must be preceded by a water spray test: Free drop (from 0.3 to 1.2 metres), depending on the mass of the package, Stacking or compression, Penetration (6kg bar dropped from 1 metre). Test sequence on one specimen in the following order: Free drop from 9 metres, Dynamic crush test (drop of a 500kg mass from 9 metres onto a specimen), Puncture test, Enhanced thermal test (fire of 800°C intensity for 60 minutes), A separate specimen may be used for the following test: Impact test (not less than 90 metres per second). If packages are altered from their original form their licence may no longer be valid. For example, the TC05 package used to be licensed for transport purpose but the addition of additional shielding to contain FGMSP skips invalidated its original license. In order to move it on the road it would need to be transported within a licensed package such as an overpack.
