ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

F63

To limit moisture condensation.

Objective:

OS2.1, OS2.3

 

APPLICATION:

Glass, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], including glass in doors and sidelights [see Sentence 9.6.6.2.(1)].
This also applies in buildings to which Part 3 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 3], with respect to glass in doors and in sidelights that could be mistaken for doors, within or at the entrance to dwelling units and in public areas, as stated in Sentences 3.3.1.19.(5) and 9.6.6.2.(1).

INTENT:

To limit the probability that the performance of glass will fall significantly below expectations, which could lead to failure, which could lead to harm to persons.
[Clause (e)] To limit the probability that the performance of insulating glass will fall significantly below expectations, which could lead to inadequate control of heat transfer, which could lead to compromised structural integrity of window assemblies and adjacent exterior wall assemblies, which could lead to condensation on interior glass surfaces, which could lead to deterioration, which could lead to harm to persons.

APPLICATION:

Insulating glass, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], including glass in doors and sidelights [see Sentence 9.6.6.2.(1)].
This also applies in buildings to which Part 3 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 3], with respect to glass in doors and in sidelights that could be mistaken for doors, within or at the entrance to dwelling units and in public areas, as stated in Sentence 3.3.1.19.(5) and Sentence 9.6.6.2.(1).

INTENT:

To limit the probability that the performance of insulating glass will fall significantly below expectations, which could lead to the inadequate control of heat transfer, which could lead to:
  • the inadequate control of temperatures in interior spaces, or
  • condensation.
This is to limit the probability of:
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of windows or adjacent exterior wall assemblies.
This is to limit the probability of:
  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.
This is to limit the probability of harm to persons.

Functional Statement:

F03

To retard the effects of fire on areas beyond its point of origin.

Objective:

OS1.2

 

APPLICATION:

Wired glass, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9]:
  • in doors or sidelights installed in fire separations between exit enclosures and floor areas, or as closures in vertical fire separations that are required to have a fire-resistance rating of not more than 1 h,
  • that is not less than 6 mm thick,
  • that has not been tested in accordance with the test methods described in Part 3, A-9.10.3.1. in Appendix A, or Appendix D, and
  • that is mounted in fixed steel frames having a metal thickness of not less than 1.35 mm and a glazing stop of not less than 20 mm on each side of the glass.

INTENT:

To limit the probability that the performance of wired safety glass will fall significantly below expectations, which could lead to failure, which could lead to the spread of fire to adjacent fire compartments, which could lead to harm to persons.
