Electrical Field Evaluation and Field Labeling

Let NSF review custom or low-volume product runs for field evaluation and labeling to ensure the products meet applicable safety requirements.

Manufacturers: Have you designed a custom product? One you’re producing in low volume? A specialty product for a single client? A prototype you want to put into service in the field? (That is, it’s not a product for mass consumption and production, which would require certification.)

The National Electrical Code (NEC) specifies in Article 90.7 that all electrical equipment must be approved. The U.S. Occupational Safety and Health Administration (OSHA) states in 29 CFR 1910.310 and the NEC states in Article 110.3 that all equipment in the workplace must be listed and labeled by a Nationally Recognized Testing Lab (NRTL) prior to operation of the equipment. As an OSHA-approved NRTL, NSF can verify that your products meet relevant electrical and safety standards.

Electrical field evaluation is ideal for ensuring a product meets OSHA requirements.
