Kiwa can provide a NSF/ANSI 61 certification mark, which identifies the strict compliance of municipal water supply products, plumbing products, including individual components and materials. All NSF/ANSI 61 certified drinking water system components are controlled by annual testing and annual factory audits to ensure continued consistency of required quality levels.
Kiwa is ISO/IEC 17065 accredited by the American National Standard Institute (ANSI). Our accreditation status and accredited scope is displayed on ANSI accreditation Kiwa Nederland.
Using NSF/ANSI 61 certified products ensures that new and installed components will not leach contaminants to the drinking water that can cause health effects and regulatory problems.
To maintain certification, manufacturers cannot change suppliers or formulations without evaluation and approval from Kiwa.
For manufacturers of practically any type of plumbing products, whether valves, faucets, tubing, backflow preventers, etcetera, etcetera) Kiwa is the right address for the testing and certifications needed to become product acceptance and code compliance across North America. Kiwa has a close cooperation with recognized North American certification agencies.
When is it required?
The vast majority of US states require NSF/ANSI 61 for municipal water product components. State agencies can issue penalties and can order removal of noncertified products.
When products are not certified to NSF/ANSI 61, manufacturers have no restrictions on changing formulations. That can lead to contamination issues as well as performance problems.
