Which term means equipment included on an acceptable evaluation organization's list?

• A. Approved
• B. Labeled
• C. Listed
• D. Shown

Answer: (C)

Listing is the term used to mean that an independent testing organization has evaluated the equipment and, if it meets the applicable standards, includes it on its official list. Being listed shows the device has been tested, complies with the standard, and is recognized for use in the system by authorities having jurisdiction. Approved is broader and not the formal indication of a product being on a specific evaluation organization’s list. Labeled refers to the presence of a label, which usually accompanies listing but does not by itself indicate inclusion on the list. Shown isn’t a standard term used to describe equipment acceptance.
