Scope

These requirements cover parts made of polymeric materials that are used in electrical equipment and describe the various test procedures and their use in the testing of such parts and equipment. These requirements do not cover the specific insulating systems that are covered by the requirements contained in the Standard for Systems of Insulating Materials@ General@ UL 1446. Test procedures are provided herein for the evaluation of polymeric materials in specific applications. These test procedures include references to data obtained from small-scale property tests conducted under standard conditions as well as other practical means of evaluation.
