Intent 1:
To exempt certain door assemblies from the requirements
of Sentence 9.10.13.1.(1), which would otherwise require testing
to determine the fire-protection rating, on the basis that:
- such doors are constructed in a manner that has been
shown to provide the required 20 min fire performance,
and
- the fire load represented by the doors and their frames
is limited, and there is no structural consequence of their eventual
failure.
