Intent
Intent 1: 
To limit the probability that improper installation or the use of inappropriate materials will lead to performance that falls significantly below expectations, which could lead to:
  • conditioned air not being delivered 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 mould and mildew growth, or
    • an 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.
