Why it’s credible

The standard was first published by NSF at the request of the U.S. Environmental Protection Agency in the late 1980s. Today, it serves as a basis for drinking water requirements around the world.

NSF/ANSI/CAN 61 remains independent, as it is managed by a joint committee of 33 representatives, consisting of equal expertise in public health, end use and industry. This structure also allows the standard to be updated to adapt to new technological advancements.

Pathway to certification

The pathway to NSF/ANSI/CAN 61 certification can be broken up into seven steps.

  • Application

    Your company submits an application (with support from our experts).
  • Submission

    You provide product formulation, toxicology, and product use information.
  • Review

    Our technical team reviews your formulations and/or parts lists to determine the testing required.
  • On-Site Audit

    We perform an on-site audit of the production facility and collect/request samples.
  • Testing

    Our laboratory conducts testing on the product.
  • Technical Evaluation

    We review the findings of the testing, audit, and compliance with the standard.
  • Certification

    If the product passes, NSF certification is granted (and maintained annually).
