Behind the Mark: Product Certification Explained
Learn about the six steps to getting certified to NSF/ANSI 60 and NSF/ANSI 61, both widely recognised standards in the water industry.
NSF/ANSI/CAN 60 and 61: The standards behind safe drinking water
NSF/ANSI/CAN 60 and NSF/ANSI/CAN 61 are North America’s leading health effects standards for drinking water safety. These standards protect public health by ensuring that chemicals and system components used in water treatment do not introduce harmful contaminants into potable water.
- NSF/ANSI/CAN 60 covers any chemical added—directly or indirectly—to treat drinking water, whether or not it remains in the finished water.
- NSF/ANSI/CAN 61 applies to any material or product that comes into contact with drinking water or treatment chemicals, from source to tap.
Why certification matters
Certification to these standards confirms that treatment chemicals and water system components meet strict health and safety requirements. This process includes:
- Full disclosure of product information by the manufacturer
- Comprehensive technical review
- Rigorous laboratory testing
- On-site audits of all manufacturing facilities.
Only products that meet every requirement earn the NSF certification mark, a trusted symbol of compliance and quality.
