The purpose of this standard is to determine whether or not ionizable soluble organic and/or inorganic materials are present in electrical insulating materials. Their presence is confirmed by the increase in volume conductivity of the liquid extract and the test is considered to have particular significance when applied to electrical insulating materials which are to be immersed in coolants or impregnants.
