ASTM E 1728 addresses which of the following?

• A. dust collection devices standards
• B. wipe sampling protocols
• C. laboratory analysis methods
• D. soil sampling methods

Answer: (B)

Wipe sampling protocols are the focus here. This standard provides the procedures for collecting surface dust samples with wipes to measure lead on various surfaces, ensuring consistency and reliability across different sites and observers. It outlines what materials to use for the wipe, how to moisturize or prepare the wipe if required, where and how large an area to sample, the technique for wiping (such as the number of passes and directions), and how to handle and preserve samples in the field. It also covers quality control aspects like field blanks and chain-of-custody to make sure results reflect the actual surface contamination rather than sampling variability. Dust collection device standards would pertain to the equipment used to collect dust, not the surface-wipe procedure. Laboratory analysis methods refer to how the collected samples are analyzed in the lab, not how the samples are collected in the field. Soil sampling methods deal with gathering samples from soil, not surface dust wipes.
