Intent

Intent 1:

To limit the probability of material incompatibility or a high rate of deterioration in the expected service environment, which could lead to the premature failure of components and assemblies of environmental separators.

This is to limit the probability of:

  • air infiltration and exfiltration,
  • condensation,
  • precipitation ingress,
  • moisture ingress from the ground, or
  • pollutant ingress, including soil gas, combustion products from parking garages, or particulates.

This is to limit the probability of:

  • the inadequate control of temperatures of interior spaces, drafts, 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 further 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.
