For the calculations required under [§ 154.406(a)(4)](/cfr/46/154.406.md?p=a-4), the following determined loads must be specially approved by the Commandant (CG-ENG):

- (a) Transient thermal loads for the cooling down periods of cargo tanks for design temperatures lower than −55 °C (−67 °F).
- (b) Stationary thermal loads for cargo tanks for design temperatures lower than −55 °C (−67 °F) that cause high thermal stress.
