What NSF/ANSI Standard covers coatings, construction materials, and components?

• A. Standard 60
• B. Standard 61
• C. Standard 62
• D. Standard 63

Answer: (B)

NSF/ANSI 61 covers materials that come into contact with drinking water, including coatings, construction materials, and components used in potable water systems. It sets health-effect criteria and testing requirements to ensure these materials won’t leach harmful substances into the water at unsafe levels. That focus on the safety of materials in direct contact with drinking water is why this standard is the correct choice for coatings, construction materials, and components. The other standards address different areas—such as drinking water treatment chemicals or other product categories—not the materials themselves, so they don’t fit this particular topic.
