ASTM E 1645 describes which process?

• A. Field collection of paint samples.
• B. Preparation of dried paint samples for laboratory analysis.
• C. Ultrasonic extraction of samples.
• D. On-site analysis of lead.

Answer: (B)

ASTM E1645 describes how to prepare dried paint samples for laboratory analysis. This standard covers converting collected paint into a consistent, homogeneous material suitable for accurate lab testing, typically involving controlled drying, grinding to a uniform particle size, and proper sub-sampling and handling to avoid contamination. By standardizing these preparation steps, lab results reliably reflect the lead content of the original paint and are comparable across laboratories. This is distinct from field sampling, on-site analysis, or extraction methods, which are governed by other procedures.
