Intent 1:
To limit the probability of waterproofing materials,
components, assemblies and systems not being capable of:
- providing an adequate resistance to water transfer in
relation to the load, or
- bridging imperfections or joints, which could lead to
discontinuity of protection at joints,
which could lead to ingress 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.
