Thank you for the reply.
If I understand well, the solution was to eliminate the frangibility requirement for tanks other than those designed to 5.10.2.6 d
i.e. removing
Uplift criteria Frangibility Pressure [(3 × Pf – 0.08th) × D2 × 785] – W3
in SI units.

Do you remove as well:
Uplift criteria Failure Pressure [(1.5 × Pf – 0.08th) × D2 × 785] – W3 ?
or rather do you interpret this criterion as in package with "frangibility"?

Best regards.
