ASTM E 1792-96a defines a standard specification for which of the following?

ASTM E 1792-96a defines a standard specification for which of the following?

• A. wipe sampling protocols
• B. dust sample transport guidelines
• C. wipe sampling materials
• D. lead content measurement methods

Answer: (C)

The main idea this item tests is understanding what ASTM E1792-96a actually sets out to specify. This standard defines the exact requirements for the wipe sampling materials used to collect lead dust from surfaces. It’s about the physical properties and performance characteristics of the wipe itself—things that ensure the material won’t contaminate the sample or behave unpredictably during collection. Think of aspects like low background lead content, minimal shedding or linting, inertness so the wipe doesn’t react with the sample, appropriate absorption and surface area to pick up dust efficiently, and defined size or area for consistent sampling. By standardizing these wipe materials, results become comparable across different sites and laboratories. It’s not about how you perform the wipe sampling (that would be a protocol), nor about how you transport the collected samples (that would be packaging/chain of custody), nor about how lead is measured once the sample is in the lab (that would be the measurement method).
