An abbreviated test can be performed when

• A. the owner agrees
• B. the owner agrees; all components tested are the same in each room equivalent; the component tested is positive for lead based paint in the first five rooms tested.
• C. all components tested are the same in each room equivalent; the component tested is positive for lead based paint in the first five rooms tested.
• D. the owner agrees; all components tested are the same in each room equivalent; the component tested is positive for lead based paint in the first five rooms tested.

Answer: (D)

Abbreviated testing works when you can confidently extend the result from a small, representative set to other similar surfaces. That requires three things: the owner has given consent to proceed with testing, the components being tested are the same across room equivalents (so results in one room can be applied to the others), and the initial testing shows lead-based paint in the first five rooms tested. When all three conditions are met, you can responsibly shorten the sampling effort by assuming the same condition across all equivalent rooms. If any of these aren’t met—no consent, or non-uniform components, or no positive results in the initial rooms—then abbreviated testing isn’t appropriate, and full sampling is required.
