  • Abstract
    A 1962 paper [1] described the single-needle test, a method of electrically stressing an artificial fault in transparent insulating polymers for the purpose of evaluating the effects of additives in improving their dielectric strength and voltage life. This paper reviews developments in test procedure since that time. Oil has replaced air as an interelectrode medium. Other details of current technique are described, and some experimental phenomena are discussed.
