NSF International recently announced that MGS Progetti has become one of the first European faucet manufacturers to demonstrate compliance with Annex G. Certification to NSF’s Annex G, which contains requirements for low lead plumbing products, helps protect the public from exposure to lead.

The new section of NSF/ANSI Standard 61-Annex G – Weighted Average Lead Content Evaluation Procedure to a 0.25 Percent Lead Requirement – includes requirements that mandate a maximum weighted average lead content of ≤ 0.25 percent. The new requirement applies to manufacturers of faucets, valves, water fittings, and other products that come in contact with drinking water.

To receive certification, MGS Progetti met the new lead content requirement of ≤ 0.25 percent and the requirements of NSF/ANSI Standard 61, Annex G. Compliance is determined by a weighted average calculation involving the maximum percent lead content of material specifications and wetted surface areas.

For meeting the new requirements, MGS Progetti’s products bear the NSF Annex G Certification Mark. MGS Progetti is also listed on the NSF Web site www.nsf.org/certified to demonstrate compliance with the new requirements.

To ensure ongoing compliance with the new lead requirements, NSF will conduct annual, unannounced inspections of the manufacturing facilities for certified products and re-test products on a regular basis.

For more information on NSF/ANSI Standard 61/Annex G requirements or NSF testing and certification services, visit NSF’s Web site or contact Pete Greiner at (734) 769-5517 or greinerp@nsf.org. A copy of Annex G as adopted in NSF/ANSI 61 – 2008 is available on the Web site.

Additional Background on the Development of Annex G The annex was developed by NSF’s Lead Task Group with guidance from key regulators, proponents of the California lead bill, industry representatives and the NSF Standard 61 Joint Committee. The NSF Joint Committee is comprised of equal representation from public health, user communities and industry to ensure an open, transparent and consensus process.
