NSF Offers Certification For Low Lead Plumbing Products To Support New State Requirements

February 16, 2009
Kohler, Moen and Price Pfister become first NSF-certified faucet companies to demonstrate compliance with new lead regulations.

NSF International announced that Kohler, Moen and Price Pfister have become the first faucet companies to get NSF certification for their plumbing products that comply with the new low lead requirements. Certification allows manufacturers to demonstrate compliance with new state laws, established to help protect the public from exposure to lead, well ahead of the January 1, 2010 deadline. Previously, it was reported that both Delta Faucet and Chicago Faucets had received similar certification for certain products from the CSA, an alternative certifying body.

The new section of NSF/ANSI Standard 61 - Annex G – Weighted Average Lead Content Evaluation Procedure to a 0.25 Percent Lead Requirement – includes the recently enacted legislation in California and Vermont that mandates a maximum weighted average lead content requirement of ≤ 0.25 percent. Other states are also considering low lead content legislation. The new lead requirements apply to manufacturers of faucets, valves, water fittings, and other products that come in contact with drinking water. Compliance with NSF/ANSI Standard 61, the American National Standard for Drinking Water Products, is also required.

NSF/ANSI Standard 61: Drinking Water System Components - Health Effects was updated in December to incorporate requirements for use when the ≤ 0.25 percent lead content requirement must be met, in addition to current chemical extraction requirements of the standard. Compliance is determined by a weighted average calculation involving the maximum percent lead content of material specifications and wetted surface areas.

To receive certification, Kohler, Moen and Price Pfister met the new lead content requirement of ≤ 0.25 percent and the requirements of NSF/ANSI Standard 61, Annex G. All three companies have been certified by NSF to Standard 61 for many years, and they now comply with the new low lead requirements well ahead of the deadline. Kohler, Moen and Price Pfister are listed on the NSF Web site with a footnote indicating compliance with the new requirements.

“By obtaining Annex G certification, Kohler, Moen and Price Pfister are emphasizing their commitment to quality and public health protection,” said Nasrin Kashefi, General Manager, NSF Plumbing Programs. “Certification is important because it expands the choices available to consumers when selecting products for their homes. We congratulate these leading manufacturers for being proactive in their response to these 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.

"Annex G is a consensus standard that took into consideration comments from key stakeholders in California and nationwide. It gives companies a valuable tool for assessing compliance with California's lead content standard. Companies that meet the standard will be at a competitive advantage,” said Bruce La Belle, Chief, California Department of Toxic Substances Control, Environmental Chemistry Laboratory.
