Is there a performance standard limiting the leaching of lead into drinking water from faucets, fittings, fixtures, pipes, and plumbing devices?

A voluntary standard, NSF International's consensus Standard 61,(NSF/ANSI Standard 61: Drinking water System Components-Health Effects), including inline and endpoint devices has been established. The criteria for lead in the NSF Standard limits the amount of lead that can leach into the water from a particular product. The standard does not specify the lead content in that product. Devices that are made of brass alloys that contain lead may be certified if they pass the performance test prescribed by the standard. Some manufacturers modified their manufacturing processes to meet the NSF Standard. NSF Standard 61, section 9 covers endpoint devices. The NSF Standard defines endpoint devices as mechanical plumbing devices, components, and materials which are typically installed within the last liter of the distribution system and are intended by the manufacturer to dispense water for human ingestion. The devices include kitchen and bar faucets, lavatory faucets, water dispensers, ...  more
