  • SCOPE

    1 Scope

    1.1 These requirements cover household cooking equipment that is floor or cabinet supported, wall-mounted, counter mounted, or combinations thereof, rated 600 V or less, for installation in accordance with the National Electrical Code.

    1.2 These requirements also cover ventilating hoods that are provided as an integral part of the cooking equipment, or that are separately supported on the building structure but arranged for factory-provided electrical connection to the cooking equipment with which they are intended to be used.

    1.3 These requirements do not cover commercial cooking appliances.

    1.4 These requirements do not cover special types of household cooking appliances. However, if such appliances are used as a part of a range, oven, surface assembly, or combination thereof, they will be judged on the basis of compliance with the requirements in this standard, insofar as they apply, and further appropriate examination and tests in accordance with the applicable requirements for electric heating appliances. These requirements do not cover all tests required on household cooking appliances having microwave ovens.

    1.5 For the purpose of these requirements, cooking equipment includes ranges, ovens, surface assemblies, or combinations thereof. A range is considered to be a combination of a surface assembly with one or more ovens. Wall-mounted cooking equipment is considered to be those appliances intended for mounting in or on a wall or other vertical surface of a building or cabinet. Counter-mounted cooking equipment is considered to be those appliances intended for mounting in or on a counter or other horizontal surface of a building or cabinet.

    1.6 In the following text, a requirement that applies only to one, two, or three of the classes of equipment coming within its scope – ventilating hoods, ranges, wall-mounted ovens, counter-mounted cooking units, or combinations thereof – are so identified. In the absence of such specific reference, or if the term appliance is employed, it is to be understood that the requirement applies to all of these classes of equipment.
