NSF International certified the first three European brass suppliers to low lead requirements for drinking water products.
The three companies are all from Italy:
• K.M.E Brass S.R.L.
• S.A. Eredi Gnutti Metalli S.P.A.
• Trafilerie Carlo Gnutti S.P.A.
The new standard outlines the testing requirements for any product that comes into contact with drinking water to ensure the product does not contribute excessive levels of contaminants, including lead, to drinking water.
NSF/ANSI Standard 61, Annex G – Weighted Average Lead Content Evaluation Procedure to a 0.25 Percent Lead Requirement – was developed to help protect the public from exposure to lead by mandating a maximum weighted average lead content of ≤ 0.25 percent in products that come into contact with drinking water. The requirements for Annex G also include compliance with NSF/ANSI Standard 61, the American National Standard for drinking water products.
The requirements apply to manufacturers of faucets, valves, pipes, water fittings, and any product that comes in contact with drinking water. Products made from an NSF-certified brass alloy require separate testing and certification to NSF 61, Annex G to ensure contamination does not occur during processing.
