Intent 1:

To limit the probability that sheet steel exposed to continual wetting will corrode, which could lead to premature failure.

This is to limit the probability of compromised integrity, which could lead to, where sheet steel is used in an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

This is to limit the probability of:

  • precipitation ingress, or
  • compromised thermal performance of components intended to provide resistance to heat transfer.

This is to limit the probability of:

  • an inadequate control of indoor air and surface temperatures or relative humidity,
  • the generation of pollutants from biological growth or from materials that become unstable upon 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.
