NSF/ANSI/CAN 61 Compliance

Keeping You in Compliance

On January 1, 2024 the NSF/ANSI/CAN 61 Section 9 Lead Leachate Standard will become mandatory.

 

Be ready with our lead-free* and low-lead brass solutions
We have excellent American-made brass solutions that will ensure you comply with the current and coming standards. Our three brass options, ECO FORGE®, ECO BRASS®, and Low Lead Brass, have been successfully used for part production and are the ideal fit to keep your components compliant as we move toward 2024. These three options provide sound solutions to continue operating in compliance with NSF/ANSI/CAN 61, Section 9 lead leachate standard. Select the brass alloy that works best for the products you are manufacturing.

 

NSF/ANSI/CAN 61 Section 9 Requirements:

    • Mandated as of January 1, 2024
    • Reduced from 5 to 1 µg for endpoint devices (e.g. faucets)
    • Reduced from 5 to 0.5 µg for components (e.g. valves)

Average “Q” values for drilled, water contact surfaces, extrapolated to 8, 20, 50 and 120 in2
