REQUIREMENTS

The basic standard used to investigate products in this category is UL 6500, "Audio/Video and Musical Instrument Apparatus for Household, Commercial and Similar General Use," or ANSI/UL 60065, "Audio, Video and Similar Electronic Apparatus - Safety Requirements."

Products investigated for use in air-handling spaces are marked "Suitable for Use in Other Environmental Air Space in Accordance with Section 300.22, (C) of the National Electrical Code," or "Suitable for Use in Air-Handling Spaces." These products have been additionally investigated to UL 2043, "Fire Test for Heat and Visible Smoke Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces." Products that bear the marking are suitable for installation in accordance with Article 300 of ANSI/NFPA 70, "National Electrical Code," Chapter 4 of ANSI/NFPA 90A, "Standard for the Installation of Air-Conditioning and Ventilating Systems," Section 602 of the "International Mechanical Code," and Section 602 of the "Uniform Mechanical Code."

Carts and similar apparatus having a top load surface that are more than one meter above the floor, and that are intended for use in schools, institutions, hospitals, or similar locations where children may move them, also comply with the applicable requirements in ANSI/UL 1667, "Tall Institutional Carts for Audio-, Video-, and Television-Type Equipment."

UL MARK

The Listing Mark of Underwriters Laboratories Inc. on the product is the only method provided by UL to identify products manufactured under its Listing and Follow-Up Service. The Listing Mark for these products includes the UL symbol (as illustrated in the Introduction of this Directory) together with the word "LISTED," a control number, and one of the following product names as appropriate: "Audio/Video Apparatus,""Audio Equipment,""Audio Product,""Audio System,""Commercial Audio Equipment,""Commercial Audio Product,""Commercial Audio System,""Musical Instrument,""Radio Receiver,""Television Equipment" (or "TV Equipment" or "TV Equip"), "Television Receiver,""Video Equipment,""Video Product,""Video System,""AV Product,""AV Apparatus," or the name of the specific type of product as shown in the individual Listings, or combinations of the product identities where required.

The category identifier for field-installed accessories includes the word "Accessory."

For rebuilt products the word "Rebuilt,""Remanufactured" or "Reconditioned" precedes the product name.

Equipment rack systems consist of an equipment rack and one or more audio or video components such as amplifiers, equalizers, VCRs and similar equipment. Each component installed in the rack that does not bear the UL Mark is identified by type and model number on a tag that is permanently attached to the rack. If all components installed in the rack bear the UL Listing Mark, the tag is not required.
