It is vital for health and safety that water system products must meet the minimum health effect requirements

What is NSF/ANSI 61?

The NSF/ANSI-61 certification was created by the National Sanitation Foundation (NSF), which is an international non-government organization whose purpose is to maintain universal health. The certification makes sure that all water system products that are related to drinking water and water-based products meet the minimum health effect requirements in regards to chemical contaminants and impurities.

The requirements for this certification are unrelated to the performance of the system or the taste of the water. This certification is now required within the majority of  Canada and the United States and is revised by a board of Canadian, American, utility representatives and product manufactures.

How Do You Certify Water Meters?

  • The first step in the process is an application sent to the NSF containing any materials or product that water comes into contact with.
  • The company must complete all of NSF’s information forms containing product information.
  • NSF then performers a toxicology report on all information submitted by the company.
  • The NSF then conducts a site inspecting of the submitted products
  • The products submitted are then taken through a 3-week testing period.
  • Using the results of the prior test the NSF conducts a toxicology report as the last step of the certification process.

After the certification is completed, the products are tested annually to make sure that the products continue to meet the standards of the certification.

Installing certified water meters is crucial for all building owners and property managers in order to maintain a healthy building environment. It also protects against any possible illness that could be caused by drinking water contamination.
As we mentioned before water certifications are mandated by almost every state and province between Canada and the U.S. so in most places it is required to be NSF/ANSI 61 certified. 

If you have any additional questions regarding NSF can be answered on our prior blog post or the NSF Library section of their website, or read more from the QMC blog below.
