About (NSF/ANSI 61)
NSF/ANSI 61 is a standard developed by NSF International and the American National Standards Institute (ANSI) to ensure the safety and quality of drinking water system components. It specifically focuses on the health effects of materials, products, and systems that come into contact with drinking water.
The NSF/ANSI 61 standard establishes criteria and testing protocols for evaluating the chemical and physical properties of products that may have contact with drinking water. This includes materials such as pipes, fittings, faucets, valves, coatings, and other components used in water distribution systems.
The main objective of NSF/ANSI 61 is to prevent the contamination of drinking water by harmful substances or excessive levels of regulated contaminants. The standard sets maximum allowable levels for various contaminants, including heavy metals, organic compounds, disinfection by-products, and other potential contaminants that may leach from materials into the water.
To achieve NSF/ANSI 61 certification, manufacturers of drinking water system components must undergo rigorous testing and evaluation by accredited laboratories. This testing includes assessing the material's impact on water quality, such as its potential to leach contaminants, as well as evaluating its overall performance and durability.
Certification to NSF/ANSI 61 provides assurance to regulators, water utilities, and consumers that the certified products meet the stringent requirements for drinking water safety. It demonstrates that the products have undergone comprehensive testing and comply with the established health-based standards.
By choosing products with NSF/ANSI 61 certification, consumers can have confidence that the materials and components used in their drinking water systems meet the necessary safety and quality standards. It helps to ensure the protection of public health by minimizing the risk of contaminants entering the drinking water supply.
In summary, NSF/ANSI 61 is a standard that evaluates and certifies the safety and quality of materials and products that come into contact with drinking water. It provides assurance that these products meet strict requirements for preventing contamination and ensuring the safety of the water supply.
