Electrical Field Evaluations
- Scope and Services
- Why Work With NSF?
- Review Process
Did an electrical or building inspector red tag your piece of equipment or want more information? Do you have a piece of equipment that is in need of a label? NSF International can provide next-day field evaluation services in most areas of the United States and Canada.
NSF is accredited by OSHA as a Nationally Recognized Testing Lab (NRTL) under the scope of field evaluation to conduct the evaluations and apply a label to meet inspectors’ criteria.
NSF’s electrical field evaluation verifies that the equipment in your facility complies with OSHA requirements. NSF provides evaluation to commonly used standards:
- UL 508A- Standard for Industrial Control Panels
- NFPA 790 and 791 standards
- Evaluations to NEC 2014 standards
- NFPA 70E: Standard for Electrical Safety in the Workplace®
- NFPA 79: Electrical Standard for Industrial Machinery
- NFPA 791- Recommended Practice and Procedures for Unlabeled Electrical Equipment Evaluation
- BE EN 61010-1 - Safety Requirements for Electrical Equipment for Measurement Control and Laboratory Use
- BS EN 60204-1 - Safety of Machinery. Electrical Equipment of Machines
- OSHA 1910.303 - General Requirements-Standard Interpretations
For companies located in southeast Michigan, NSF can offer a free and same-day on-site estimate. For more information, contact firstname.lastname@example.org.

Part of the evaluation requires a safety check. NSF may have to test the equipment using these different types of tests:
- Grounding and continuity test: Testing proper grounding of the entire piece of equipment
- Dielectric voltage test: Testing for proper spacing between parts. The test is performed between primary and ground as well as primary and secondary of the equipment.
- Load current test: Testing the input current during max load operation and checking for all protection mechanisms such as fuses, circuit breakers, wire size and overloads
- Strain relief: Testing the strength of the strain relief of cords through a push and pull test
- Emergency/interlock test: Testing the emergency stop functions of the equipment as well as testing the interlocking system to ensure the system shuts off in case of a fault
- NEMA 3R testing: The NEMA 3R test evaluates the overall construction of the equipment to ensure all gaskets and housings are rain-/water-tight.
NSF’s field evaluation service offers electrical power risk assessments, which are used to increase production uptime and reduce electrical-related injuries. This assessment is comprised of four steps, including risk management planning, risk identification, risk analysis and response planning.
Also offered are electrical safety and arc flash training. NSF International can conduct on-site training for your employees to meet OSHA standards, as all employees must be trained on electrical safety for all equipment used in the workplace. Arc flash training is designed for any qualified worker at your facility, typically maintenance workers and or electricians, and details the dangers and consequences of arc flash.
Field evaluations protect your company and employees, ensure that the equipment is safe for use and demonstrate product safety and reliability.
An evaluation can lower the risk of product liability action, reduce the occurrence or cost of a workplace injury and/or employee downtime and assure that the equipment adheres to safety requirements.
Field evaluations can also help your organization comply with regulation, as local inspectors may require that equipment be evaluated by an OSHA Nationally Recognized Testing Laboratory (NRTL).
NSF field evaluation services also provide:
- Highly trained auditors with knowledge of safety standards
- Ability to work congruently with inspector and authorities having jurisdiction (AHJ)
- Compliance to OSHA standards for electrical safety in the workplace
- Expert assistance to non-compliant equipment
- Preliminary scheduling of equipment at the original location to speed up evaluation process
Why Work With NSF?
NSF is accredited by OSHA as a Nationally Recognized Testing Laboratory (NRTL) to provide electrical safety approval to various UL/ANSI/NFPA standards in the United States and by the Standards Council of Canada for product listing and certification. We have trained professionals throughout the United States, Canada, Mexico and Europe. As a NRTL, we determine what equipment and materials meet consensus-based safety standards, as required by OSHA, and that these products are safe for use in the U.S. workplace.
We listen to your company and can recommend a custom solution for your organization’s specific needs. Based on your company’s assessed risk level and other needs, NSF has the capability and expertise to offer a number of solutions custom-tailored for your company, from field evaluations to modified UL listed products, safety training and more.
As NSF is based in Ann Arbor, MI, we can provide free and same-day on-site estimates to companies located in southeast Michigan.
NSF credentials include:
- A Nationally Recognized Testing Laboratory (NRTL) accredited by OSHA
- Accepted throughout the United States and Canada
- Member of IAEI (International Association of Electrical Inspectors)
- Member of NFPA (National Fire Protection Agency)
- Member of ANSI (American National Standards Institute)

The electrical review process consists of the following steps:
- Documentation: Contact NSF and provide us with all documentation pertaining to the equipment to be inspected.
- On-site evaluation: NSF will conduct an on-site evaluation of the equipment and provide steps to correct the equipment if needed.
- Corrective action report: Our expert staff will issue a corrective action report after the on-site evaluation. The corrective action report will document any items that are in need of correction.
- Final labeling: If corrections are made and the equipment passes, NSF will approve the equipment and send the test report to your company.
