Room equivalent is a part of a residence EG: room, house exterior, hallway, etc.
Each room equivalent is comprised of components such as floor, wall or ceiling.
A testing combination is comprised of the room equivalent, component type, substrate and visible paint color
Inspect each testing combination in each room equivalent, unless similar building component types with identical substrates (such as windows) are all found to contain lead-based paint in the first five interior room equivalents.
