现场评估

Understanding field evaluations

It is common for products and electrical equipment to be unevaluated, customized or modified in the field to meet the specific needs of an application. Modifications may affect existing certifications. A field evaluation allows products and equipment lacking certification or modified to be evaluated in accordance with the appropriate product safety standard(s) for the specific application and location where the product is being utilized. Construction reviews and other on-site tests can be completed to confirm that applicable standards and regulations are being met.

This process helps fulfill regulatory requirements and assists the code authority to approve the installation. The process includes construction inspection for use of components and other on-site tests, including assembly and limited nondestructive testing, to complete the assessment.
