| Objective | OP3 Protection of Adjacent Buildings from Fire |
| Attribution | |
| Application | Application 1: Calculating the area of unprotected
openings in an exposing building face,
where the surface temperature on the unexposed surface of a wall assembly
exceeds the temperature limit of a standard fire test as provided in Article 3.1.7.2., in buildings described in Sentence 1.3.3.2.(1) of Division A. Application 2: This also applies to the rating for exposure to fire
of exterior walls in buildings to which Part 9

9], as stated in Sentence 9.10.3.3.(2). |

| Intent | Intent 1: To state how to treat radiation from the hot unexposed wall
surface and add an equivalent area in calculating the area of unprotected
openings in an exposing building face. This is to limit the probability of
the spread of fire from the building to an adjacent building, which could
lead to damage to adjacent buildings. |
