Underwriters Laboratory – UL – is a well-known and trusted laboratory which examines and certifies thousands of products.
UL certifies drinking water treatment chemicals under NSF Standard 60, possibly including fluoridation materials such as silicofluorides and sodium fluoride.
ANSI/NSF Standard 60 — Drinking Water Treatment Chemicals — Health Effects
UL provides the expertise and quality services you need to meet the requirements of ANSI/NSF Standard 60. Our comprehensive compliance services include a Follow-Up Services program, which involves periodic surveillance of manufacturing facilities as a requirement to maintain UL product certification.
Our comprehensive testing and certification services include certification to ANSI/NSF Standard 60. Product categories include:
- pH adjustment
- Coagulation and flocculation
- Disinfection and oxidation
- Corrosion and scale control
- Softening
- Sequestering
- Precipitation
We also work to make sure that your needs are being met in the industry. Our dedicated team of toxicologists actively participates in national water products standards committees. We also retain a council of experts in environmental and public health to oversee what we do, ensuring that we continue to deliver the highest quality work to you.
When your products bear the UL Water Quality Mark, you get the mark that is recognized by the Environmental Protection Agency, accredited by ANSI, accepted in all 50 states and preferred by regulators.

A phosphate fertilizer company will have toxic waste slurry liquor, containing silicofluorides and scores of other acids, compounds, and elements left over after manufacturing super-phosphate fertilizer.
To be able to sell this toxic waste slurry liquor to water departments, a company needs to obtain NSF 60 certification. UL provides such certification. To start the process a company fills out UL’s application form, found here.
The National Sanitation Foundation claims that suppliers of fluoridation materials provide toxicological studies or that NSF performs toxicological studies. NSF representatives have admitted that there are no toxicological studies.
For these reasons Underwriters Laboratory should be on notice that it may be subject to potential liability for its certification of silicofluorides as appropriate for injection into drinking water.
