Back5.6.1.3.(1)

ATTRIBUTION:

Functional Statement:

F61

To resist the ingress of precipitation, water or moisture from the exterior or from the ground.

Objective:

OH1.1, OH1.2, OH1.3

 

APPLICATION:

Installation of materials to provide protection against precipitation ingress in sloped or horizontal assemblies that are exposed to precipitation, where such installation is within the application of the standards listed.
This applies to building materials, components or assemblies and their interfaces described in Sentence 5.1.2.1.(1) that are installed in buildings to which Part 5 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 5].

INTENT:

To limit the probability that the performance of the installed material, with respect to protection against precipitation ingress, will fall significantly below expectations, which could lead to precipitation ingress.
This is to limit the probability of:
  • the inadequate control of relative humidity or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of environmental separators.
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.

ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

F61

To resist the ingress of precipitation, water or moisture from the exterior or from the ground.

OS2.1, OS2.3

 

APPLICATION:

Installation of materials to provide protection against precipitation ingress in sloped or horizontal assemblies that are exposed to precipitation, where such installation is within the application of the standards listed.
This applies to building materials, components or assemblies and their interfaces described in Sentence 5.1.2.1.(1) that are installed in buildings to which Part 5 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 5].

INTENT:

To limit the probability that the performance of the installed material, with respect to protection against precipitation ingress, will fall significantly below expectations, which could lead to precipitation ingress.
This is to limit the probability of:
  • the inadequate structural strength and integrity of the installation, which could lead to falling components, or
  • deterioration, which could lead to compromised structural integrity of the separators or of elements supported or protected by the separators.
This is to limit the probability of harm to persons.
