    1.1 These requirements apply to shelves, brackets, and similar devices, that provide structural support for the mounting of audio/video equipment, information technology equipment, and similar products, to the building structure and are intended for indoor use only.

    1.2 These requirements also apply to accessories that are used to expand the capability of a mounting device; accessories that are used to secure the mounting device to a wall, ceiling, suspended ceiling, truss, joist, "I" beam, or other building structural component specified by the manufacturer; and any accessories used to secure an apparatus to the mount. Examples of such products include extension columns, extension arms, ceiling plates, floor plates, ceiling brackets, fastener kits, and VCR/DVD brackets.

    1.3 A furnishing intended to support audio equipment or a video display (such as CRT, LCD, and Plasma) is to be evaluated in accordance with one of the following:

    a)    A furnishing such as a desk or a retail store display intended to support a video display but not intended for use as a mobile cart for the video display is covered by the Standard for Household and Commercial Furnishings, UL 962;

    b)     A video display sign is covered by the Standard for Electric Signs, UL 48;

    c)      If the furnishing is provided with casters, wheels, or is an entertainment center, the Standard for Household, Commercial, and Institutional-Use Carts, Stands and Entertainment Centers for Use with Audio and/or Video Equipment, UL 1678 applies;

    d)     If the audio or video equipment is intended to be mounted to walls, ceilings or another permanent part of a building as the primary support means, this standard applies;

    e)     If a furnishing is supplied with all of the video and/or audio components by the manufacturer of those components, the requirements contained in the Standard for Audio, Video and Similar Electronic Apparatus – Safety Requirements, UL 60065, or the Standard for Information Technology Equipment – Safety – Part 1: General Requirements, UL 60950-1, or the Standard for Safety for Audio/Video, information and communication technology equipment – Part 1: Safety Requirements, UL 62368-1, apply as appropriate.

    A video display support system evaluated in accordance with (a) – (d) above and supplied with all of the video and/or audio components is not subject to (e).

    1.4 These requirements do not apply to carts and stands. The Standard for Safety for Household, Commercial, and Institutional-Use Carts, Stands and Entertainment Centers for Use with Audio and/or Video Equipment, UL 1678, applies to these products.

    1.5 These requirements do not apply to a mounting device provided with a specific product when the specific product standard is provided with requirements to address the mounting device. Such combinations are covered by the applicable requirements of the end-use product standard.

    1.6 These requirements do not cover products intended for use in patient care areas. Patient care products are covered by the Standard for Medical Electrical Equipment, Part 1: General Requirements for Safety, UL 60601-1.

    1.7 These requirements do not cover products that are specifically intended for infants or juveniles.

    1.8 These requirements do not cover the mount to supported apparatus interface.
