9.10.13.2.(1)

Intent

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.
