IEC EN 61857-33 Electrical Insulation Systems - Thermal Evaluation Methods - Part 33: Multi-Factor Evaluation with Increasing Aging Factors at High Temperature

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61857-33 testing. This part of the IEC EN 61857 series is applicable to the evaluation of an EIS for applications where the application voltages are a combination of the multi-factor voltages specified in IEC 60505.

Increased stress factors are expected to occur during service at high temperatures. This standard specifies a method for evaluating the effect of voltages on observed performance following thermal classification of the EIS. EIS research is initially evaluated based on thermal stress only.

This standard deals with thermal endurance testing involving one or more additional stresses during the thermal aging process. Provides guidance on how to interpret test results. For products designed and manufactured for EIS application, the IEC technical committee responsible for the application should be consulted regarding the performance requirements set out in this document. This standard applies to a number of established EIS testing standards.
