Update; I found a global assessment for the doors in a single acting double door set.
It failed before 30 minutes on the latch but there is a note stating if the forend etc had intumescent strips it would likely hold for 30.
I've sent this on with a pointer to the AD and the requirement for FD20 asking for confirmation. I await the outcome.
