In response to requests from IAS-accredited testing laboratories, inspection agencies and
authorities having jurisdiction (AHJs), IAS developed an accreditation program for the field
evaluation of unlisted electrical equipment. The program is designed to formalize an
accreditation process for agencies conducting evaluations of electrical equipment. The request
for these types of evaluations usually comes from a building department, code enforcement
official, fire marshal or similar regulatory body. The request for field evaluation is primarily to
determine compliance with applicable codes or standards of one-of-a-kind, limited production,
used or modified products that are not listed or labeled under a full listing or certification
program. The evaluation process may be completed at the point of manufacture, interim points
of distribution, in the evaluating organization’s facilities, in situ or a combination of the above.
The criteria used to assess field evaluation bodies pursuing accreditation is IAS Accreditation
Criteria for Field Evaluation of Unlisted Electrical Equipment (AC354).
