Intent 1:
To limit the probability of an inadequate resistance
to moisture transfer in relation to the moisture load, which could
lead to moisture ingress from the ground.
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.
