  • NSF 61

    NSF/ANSI 61 addresses the human health effects of drinking water system components. This performance-based standard evaluates the amount of contaminants that leach from the products into potable drinking water. The origin for this standard was lead reduction/ removal. Any lead that elutes into the water at over 0.25% fails this standard.

  • NSF 372

    NSF/ANSI 372 establishes a standardized methodology for the determination and verification of product compliance to minimize lead contaminants. This standard is consistent with the United States Safe Drinking Water Act (SDWA) and its lead-free plumbing requirements, as well as the requirements of individual U.S. states such as California.
