Intent 1:
To limit the probability of the inadequate bonding
of plies, which could lead to inadequate tensile strength, which could
lead to an inadequate resistance to traffic loads or resistance to
water infiltration and freeze-thaw cycling, which could lead to tearing
or puncturing of membranes, which could lead to:
- water penetrating directly to roof decking or sheathing,
or
- compromised thermal performance of components intended
to provide resistance to heat transfer.
This is to limit the probability of:
- an inadequate control of relative humidity, temperatures
of interior spaces 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 roofs or assemblies protected by roofs.
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.
