What body sets the standards for dust wipe sample approval?

The organization responsible for setting the standards for dust wipe sample approval is ASTM (American Society for Testing and Materials). This body's standards are crucial for ensuring consistency and reliability in the testing methods used to assess lead dust levels in various environments, particularly in homes and buildings where lead exposure is a concern.

ASTM develops these standards to provide guidelines that professionals can follow when collecting and analyzing dust samples, ensuring that the methodology adheres to strict quality control measures. These standards help to ensure that the results obtained from dust wipe samples are valid and comparable across different assessments, which is essential for effectively managing lead hazards in residential and commercial settings.

The other organizations mentioned have different focuses; for instance, the EPA (Environmental Protection Agency) deals with broader environmental regulations and guidelines but does not specifically set the standards for dust wipe sample approval. The ISO (International Organization for Standardization) provides international standards but may not focus specifically on lead sampling protocols. The CDC (Centers for Disease Control and Prevention) primarily focuses on public health guidelines and safety standards but does not set the technical standards for dust sampling.

In summary, ASTM is the key organization responsible for establishing consistent testing protocols that ensure accurate assessments of lead dust contamination, making it the correct answer.
