ASTM E 1728 and AST M E 1792-96a pertain to which of the following?

ASTM E 1728 and AST M E 1792-96a pertain to which of the following?

• A. ASTM E 1728 governs wipe sampling protocols, and ASTM E 1792-96a governs wipe sampling materials.
• B. ASTM E 1728 governs wipe sampling materials, and ASTM E 1792-96a governs wipe sampling protocols.
• C. Both standards relate to blood lead testing.
• D. These standards do not pertain to wipe sampling.

Answer: (A)

The key idea is understanding what each ASTM standard covers for wipe sampling in lead-dust assessment. ASTM E1728 defines the wipe sampling protocols—the procedures you follow in the field or lab to collect wipe samples, including how to prepare surfaces, how much area to sample, handling of samples, and QA/QC and documentation. ASTM E1792-96a, on the other hand, specifies the wipe sampling materials themselves—the type of papers or pads to use, and their properties to ensure reliable sampling. So the pairing that E1728 governs the wipe sampling protocols and E1792-96a governs the wipe sampling materials is correct. This topic isn’t about blood lead testing, which is addressed by different standards and methods, and it isn’t about wiping sampling being irrelevant.
