Dust wipe media must meet what criteria?

Dust wipe media must meet what criteria?

• A. ASTM E 1792 laboratory criteria
• B. ISO 9001
• C. EPA Method 3050B
• D. ASTM D 4318

Answer: (A)

Dust wipe sampling relies on media that won’t skew the results. ASTM E 1792 provides the laboratory criteria for wipe media, outlining the quality assurance characteristics the material must meet—such as low background contamination, clean and consistent surface properties, and proper lot testing. Meeting these criteria ensures that any lead detected comes from the surface being sampled, not from the media itself, and allows results to be reliable and comparable across samples and labs. The other standards listed aren’t specific to wipe media quality: ISO 9001 is a general quality-management standard, EPA Method 3050B is a digestion method for metals, and ASTM D 4318 relates to soil properties.
