Field Labeling

NSF sanitation certification of commercial food equipment is the preferred method of receiving acceptance of the equipment by the authority having jurisdiction (AHJ), such as state and local health departments. Periodically, there may be special circumstances where a piece of equipment that is not certified needs to be installed and operated in a commercial food establishment. This could happen when a specialty equipment item is not currently available as a certified product, when prototype equipment undergoes in-use testing or in other instances when an establishment has purchased a piece of equipment that is not certified. Under these circumstances the AHJ typically does not have the necessary knowledge of the equipment or the confidence to accept it without a sanitation certification.

In these cases, the AHJ may be willing to review a field evaluation report from NSF to determine acceptance of the equipment in lieu of certification. NSF's field labeling services can provide the necessary information about the compliance of the product, allowing the AHJ to make an informed decision on its acceptance.

NSF's field labeling services include:

  • A physical evaluation of the product to applicable NSF/ANSI sanitation standards by NSF technical experts
  • A detailed report of the findings
  • An "NSF Field Evaluated" label placed on the product to indicate that is has been field evaluated.


NSF's field labeling services offer a solution for prototype testing and the operation of equipment that is not NSF certified. In order for field labeling to become a solution, it must first be accepted by the authorities having jurisdiction. It is not intended to replace certification, but serves as a solution when certification is not possible. This service provides an evaluation to applicable NSF/ANSI sanitation standards, a detailed report and an NSF field label for equipment already in the field.

Why Work With NSF?

Working with NSF means you benefit from the experience of the developer and main certifier of the NSF/ANSI sanitation standards. The NSF field label offers customers and regulators an evaluation report of your products by the experienced technical experts who developed and maintain the NSF standards.


The NSF field labeling process provides a thorough and efficient field evaluation by NSF technical experts. The process is coordinated by experts dedicated to expedite your evaluation and involves these steps:

  1. An equipment manufacturer or restaurant operator identifies a need for a field evaluation for a pre-production prototype or a product that is not certified.
  2. The authority having jurisdiction confirms that a field evaluation may be a solution in that instance.
  3. The representative of the establishment or of the equipment manufacturer contacts NSF to request the evaluation and a quote for services. They also provide details of the equipment, the location of the equipment and the desired timing of the evaluation.
  4. NSF schedules and conducts the evaluation, and labels the evaluated product with an NSF field evaluation label.
  5. NSF generates the evaluation report and sends it to the representative requesting the evaluation and the authority having jurisdiction.
