(See A-3 in Appendix A .) (See also Article 3.1.6.3.)2) The area of the unprotected openings in an exposing building face shall be the aggregate area of unprotected openings expressed as a percentage of the area of the exposing building face in Table 3.2.3.1.A, Table 3.2.3.1.B, Table 3.2.3.1.C or Table 3.2.3.1.D (See Sentence 3.2.3.2.(1).)
3) For the purpose of determining the type of
construction and cladding and the fire-resistance rating of an exterior wall,
a)the exposing building face shall be taken as the projection of the exterior wall onto a vertical plane located so that no portion of the exterior wall of the building or of a fire compartment, if the fire compartment complies with the requirements of Article 3.2.3.2., is between the vertical plane and the line to which the limiting distance is measured, and
b)the area of unprotected openings shall be determined from Table 3.2.3.1.A, Table 3.2.3.1.B, Table 3.2.3.1.C or Table 3.2.3.1.D
4) For the purpose of determining the actual percentage
of unprotected openings permitted in an exterior wall, the location of the exposing building face is permitted to be taken at a
vertical plane located so that there are no unprotected openings between the vertical plane and the line to which the limiting distance is measured. (See Appendix A.)
5) If a building has any storey that is not sprinklered and firefighting facilities cannot reach it within 10 min of the alarm being received, the limiting distance shall be doubled.
6) If the surface temperature on the unexposed surface of
a wall assembly exceeds the temperature limit of a standard fire
test as permitted by Article 3.1.7.2., an allowance shall be made for the radiation from the hot unexposed wall surface by adding an
equivalent area of unprotected opening to the area of actual openings as follows:
where
| AC | = corrected area of unprotected openings including actual and equivalent openings, |
| A | = actual area of unprotected openings, |
| AF | = area of exterior surface of the exposing building face, exclusive of openings, on which the temperature limit of the standard test is exceeded, and |
| FEO | = an equivalent opening factor derived from the following expression: |
| Tu | = average temperature in degrees Celsius of the unexposed wall surface at the time the required fire-resistance rating is reached under test conditions, |
| Te | = 892°C for a fire-resistance rating not less than 45 min, 927°C for a fire-resistance rating not less than 1 h, and 1 010°C for a fire-resistance rating not less than 2 h. |
7) Unless a closure used to protect an opening in an exposing building face has a protective performance equivalent to that
required for the wall assembly in which it is located, an
equivalent area of unprotected opening, determined in accordance with the procedures of
Sentence (6)shall be added to the greater of
a)the actual area of unprotected openings, or
b)the corrected area of unprotected openings.
