Installed electrical products or assemblies that are not previously certified, listed, recognized, or classified undergo a "field evaluation" to ensure electrical safety. Newly created to meet industry needs, the 2012 edition of NFPA 790: Standard for Competency of Third-Party Field Evaluation Bodies provides qualifications and competencies for third parties performing field evaluations and specifies how they are to be completed.

Used in tandem with the new NFPA 791: Recommended Practice and Procedures for Unlabeled Electrical Equipment Evaluation, this Standard is essential for personnel involved with evaluating:

• Electrical products not pre-certified, listed, recognized, or classified to an applicable product safety standard
• Electrical products and assemblies that are unique or modified after the manufacturing process

Users of this first-time Standard include fire marshals and AHJs.
