What is the measurement of a wipe called that is required in the lead testing process?

At least 1 hour
0.5%
All layers of paint
15 ppb

The correct answer is: At least 1 hour

In the lead testing process, the measurement of a wipe refers to a specific time period during which a surface is wiped to collect samples for analysis. The correct answer indicates that the wipe must be conducted for at least 1 hour to effectively collect lead dust or residues present on surfaces. This duration is significant because it allows for a thorough and adequate collection of samples that are representative of lead presence in the environment. By ensuring that the wipe test covers this time frame, the results will reflect a more accurate measurement of lead exposure risk. Other choices relate to different aspects of lead testing and exposure but do not specifically address the required measurement duration of the wipe. For instance, percentages and parts per billion (ppb) are concentration measurements rather than time-based methodologies for sample collection. The reference to all layers of paint pertains to the evaluation of paint surfaces but does not connect to the wipe sampling technique used in assessing lead levels.
