Scope
1.1 This Standard applies to single-or multiple-conductor, round, flat, or coiled appliance wiring material products classified as follows: (a) Class I – internal wiring of equipment (single- or multiple-conductor constructions with or without a covering or jacket): (i) Group A – not subject to mechanical abuse; and (ii) Group B – potentially subject to mechanical abuse: (1) wet; and (2) oil; and
(b) Class II – external/interconnecting wires (single- or multiple-conductor constructions with a jacket): (i) Group A – not subject to mechanical abuse; and (ii) Group B – potentially subject to mechanical abuse: (1) wet; and (2) oil.
Notes: (1) As there is a great variety of applications for appliance wiring material products, the use of such a product should be evaluated with the design and construction of the end-use application in mind and should not be judged solely by the requirements of this Standard. (2) Class I and II products are Group A, B, or both. (3) Group markings (A, B, or both) relate to tests performed on the individual insulated conductors. Group marking that includes both A and B means all insulated conductors pass Group B tests.
