NSF International is at the forefront of the low-lead plumbing products issue, having actively worked with the State of California and other key States for over fifteen years, through the ongoing development of NSF/ANSI Standard 61 (NSF 61). The standard has played a key role in CA Proposition 65 lead settlements and is now the American National Standard for lead content in plumbing products.
Most recently, NSF developed the evaluation procedures in NSF/ANSI Standard 372 (NSF 372) to establish an American National Standard to determine product compliance with the ≤0.25% percent maximum weighted average lead content requirement. NSF/ANSI Standard 61, Annex G (NSF 61-G) references NSF 372. Certification to NSF 61-G or NSF 372 meets the requirements of the California Health and Safety Code (Section 116875; commonly known as AB1953) as well as for other states developing similar regulations. This also meets the new low lead requirements of the U.S. Safe Drinking Water Act, which go into effect in January 2014.
NSF offers certification to NSF 61-G and NSF 372 to manufacturers of products that contact drinking water, including faucets, flexible plumbing connectors, valves, meters and many other product types.

NSF/ANSI Standard 61 was revised in December 2008 to establish requirements for use when a 0.25% lead content requirement needs to be met in addition to current chemical extraction requirements of the standard. The requirements were placed in Annex G - Weighted Average Lead Content Evaluation Procedure to a 0.25% Lead Requirement. In addition, mandatory language placing restrictions on the use of lead as an intentional additive in water contact materials was also added to Section 3. To view the full content of the annex as adopted in NSF/ANSI 61 - 2008, download the PDF document.
A request was made to add these requirements to the standard to allow manufacturers the option of being certified to a lead content standard, such as California's Health & Safety Code (Section 116875) commonly known as AB1953. That law, which goes into effect January 1, 2010, applies to any pipe, pipe of plumbing fitting, or fixture intended to convey or dispense water for human consumption through drinking or cooking. A similar law has been enacted in Vermont and is also to take effect January 1, 2010.
The annex was developed through the Lead Task Group of the Drinking Water Additives Joint Committee and includes requirements that enable conservative and consistent application of the lead content evaluation procedure. Highlights include:

To search for of NSF-61 Annex G certified products, visit the NSF listings page on the public website. Remember to look for the Annex G footnote on the listings page which states, "Product also Certified to NSF/ANSI Standard 61, Annex G (weighted average lead content of ≤0.25%) and is in compliance with California's Health & Safety Code Section 116875 (commonly known as AB1953.)."
You may also access the complete lists of NSF-certified products to Annex G:
Products that are NSF-certified to NSF/ANSI Standard 61, Annex G utilize a special certification mark that designates the addition of Annex G certification. This will vary slightly depending on whether the product is certified to NSF/ANSI Standard 61, NSF/ANSI Standard 61, Section 9, or NSF/ANSI Standard 14 (which references NSF 61).
The NSF Annex G certification marks can be downloaded via the NSF marks download page.
Should you have any questions about product marking, contact your NSF certification project manager, or Hilary Brazin, NSF Marketing Manager, at (+1) 734-827-5678 or email@example.com.
Products that have been certified only for the weighted average lead content and not NSF 61 compliance may bear the following marks:
