What Class rating is associated with the smoker damper leakage?

In the context of commercial building inspections, the rating of smoke dampers is crucial for ensuring compliance with safety standards related to fire and smoke control within buildings. The Class rating associated with smoke damper leakage is Class I and Class II, which are meant to define the level of permissible leakage for dampers operating under specific conditions.

Class I dampers are typically designed for low leakage applications, while Class II dampers can allow a higher level of leakage but still meet certain performance standards. The classification usually depends on the construction and intended use of the damper in the HVAC system and its ability to control smoke in case of a fire.

Given that both Class I and Class II dampers are recognized based on their respective leakage criteria, the appropriate rating for dampers dealing with smoke is indeed either Class I or Class II. This dual possibility reflects the need to accommodate different building environments and designs while still addressing safety and regulatory requirements. Thus, recognizing that both classes are applicable points to the correct answer being that either could indeed describe the smoke damper leakage classification.
