Evaluation and qualification of electrical insulation systems Ingestion-build-256245 9 standard is a part1 Scope This International Standard establishes the basis for estimating the ageing of electrical insulation systems (EIS) under conditions of either electrical, thermal, mechanical, environmental stresses or combinations of these (multifactor stresses). It specifies the principles and procedures that shall be followed, during the development of EISfunctional test and evaluation procedures, to establish the estimated service life for a specific EIS.
