Which ASTM standard covers field collection of dried paint samples for lead determination?

• A. ASTM E 1645
• B. ASTM E 1775-96
• C. ASTM E 1979-98
• D. ASTM E 1729

Answer: (D)

Field sampling of dried paint for lead determination is guided by a standard that explains how to plan and perform specimen collection in real-world settings, so the samples are representative, uncontaminated, and suitable for lab analysis. ASTM E1729 provides this guidance for sampling building materials for lead in paint, including dried paint films, covering where to take samples, how many should be collected, and how to package, label, and preserve them for transport to the laboratory. This ensures the integrity of the samples from collection through analysis and helps achieve reliable lead determinations. The other standards focus on different aspects—such as procedures for analysis or preparation after collection—instead of the field collection process itself, so they don’t address choosing sampling locations, collecting dried paint films, and preserving them in the field to the same extent.
