49、evices and the effect of these changes on the thermal classification of the established EIS. This Part 2 of IEC 61858 is for form-wound EIS. Part 1 of IEC 61858 addresses modifications of wire-wound EIS. General principles for evaluation and qualification of EIS can be found in IEC 60505. Unless the procedures of this standard indicate otherwise, the principles of IEC 60505 should be followed.
