    Welcome to the IEC 60505 database

    IEC 60505 (Evaluation and qualification of electrical insulation systems) 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 should be followed, during the development of EIS functional test and evaluation procedures, to establish the estimated service life for a specific EIS.


    The database is maintained by TC 112 (Evaluation and qualification of electrical insulating materials and systems).
