Intent

Intent 1:

To limit the probability that the performance of ducts or fittings will fall significantly below expectations, which could lead to:

  • a failure to deliver conditioned air to designated locations, which could lead to
    • an inability to maintain adequate indoor air temperatures or to control relative humidity, which could lead to condensation, which could lead to the growth of mould and mildew, or
    • the inadequate control of airborne pollutants, or
  • in the case of ventilation systems, depressurization in buildings, which could lead to the spillage of combustion products from fuel-fired appliances.

This is to limit the probability of negative effects on the air quality of indoor spaces, which could lead to harm to persons.
