What is the allowed quantity of lead in dry surface paint when testing with paint chip?

• A. 1000 ppm
• B. 5000 ppm
• C. 100 ppm
• D. 0.5%

Answer: (B)

In paint-chip testing, the threshold used to classify paint as lead-based is 5,000 parts per million, which is the same as 0.5% by weight. If a dry film shows lead at or above this level, it is considered lead-based and requires the appropriate safety and regulatory handling. So the allowed quantity that defines lead-based paint is 5,000 ppm (0.5%). The other values are either below the threshold (1,000 ppm or 100 ppm) or simply another way to express the same limit (0.5%), confirming that 5,000 ppm is the critical cutoff.
