Intent 1:
To limit the probability that an inadequate resistance
to moisture or corrosion will lead to condensation in ducts due to
contact with wet soil or other sources of moisture, which could lead
to the deterioration and collapse of ducts, which could lead to a
reduction in airflow, which could lead to:
- the inadequate control of:
- relative humidity or indoor air temperatures,
- surface temperatures, or
- air velocity, or
- an inability to maintain adequate indoor air temperatures,
which could lead to the condensation of moisture from interior spaces
on interior surfaces or within assemblies, which could lead to compromised
integrity of environmental separators or of elements protected by
such separators.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
and
- the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
