A testing combination is defined as a unique combination of

• A. weather, time, and humidity
• B. the color of the paint
• C. room equivalents, building component types, or substrates
• D. the type of soil

Answer: (C)

In lead-based paint testing planning, a testing combination is the specific set of conditions you use to plan which surfaces to test. It means a unique pairing of room equivalents, building component types, and substrates. This ensures you sample surfaces that represent the range of conditions found in the building, so the results reflect potential lead hazards across different areas and materials. For example, one testing combination might be a living room wall (room equivalent) made of drywall (substrate) as a particular component type, while another might be a kitchen doorframe (different room equivalent and component) made of wood. The other options describe factors or surface characteristics that don’t define how testing combinations are chosen.
