The RRP federal standard states paint is considered lead positive at or above the level from the XRF. What is that level?

• A. 0.5 mg/cm2
• B. 2.0 mg/cm2
• C. 5.0 mg/cm2
• D. 1.0 mg/cm2

Answer: (D)

Lead-based paint under the RRP is defined by the amount of lead per area measured by XRF. The level used for XRF screening is 1.0 mg of lead per square centimeter. If an XRF reading is at or above 1.0 mg/cm2, the paint is considered lead-positive and falls under the lead-based paint requirements. This threshold aligns with the traditional destructive testing threshold of 0.5% by weight, providing a consistent standard across testing methods.
