Back5.6.2.1.(1)

ATTRIBUTION:

Functional Statement:

F61

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

F62

To facilitate the dissipation of water and moisture from the building.

Objective:

OH1.1, OH1.2, OH1.3

 

APPLICATION:

Materials, components, assemblies, joints in materials, and junctions between components or assemblies that are:
  • exposed to precipitation, and
  • installed to provide protection against precipitation ingress in assemblies.
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].
This also applies to cladding assemblies installed on buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] where:
  • the cladding assembly is not addressed in Section 9.27., or
  • the cladding assembly does not comply with the prescriptive requirements of Section 9.27.

INTENT:

To limit the probability of:
  • the inadequate control of precipitation ingress, or
  • the inadequate provision for dissipation of precipitation that does enter an assembly, which could lead to the ingress or accumulation of water.
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.

INTENT:

To limit the probability of:
  • the inadequate control of precipitation ingress, or
  • the inadequate provision for dissipation of precipitation that does enter an assembly, which could lead to ingress or accumulation of water.
This is to limit the probability of deterioration, which could lead to compromised structural integrity of the separators or of elements supported or protected by the separators, which could lead to structural failure, which could lead to harm to persons.
