Intent 1:
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.
