9.13.2.1.(3)

Intent

Intent 1:

To exempt certain floors from the application of Sentence 9.13.2.1.(2), where:

  • the ingress of moisture that is not under hydrostatic pressure will not adversely affect health or safety owing to
    • the high air leakage rate of the floors, which rapidly removes moisture from the space, or
    • the typically short duration of the presence of occupants, or
  • other actions are taken to limit the ingress of moisture.
