Meet regulations and market requirements. Develop more reliable products.

Until recently, Electrical Insulation Systems (EIS) recognition for electrical products was required only in the United States by manufacturers seeking recognition under UL 1446. However, with the adoption of IEC 61857 and IEC 61858 by IEC member nations, the concept of using EIS is now a global reality. For those nations automatically adopting IEC standards as national standards, EIS are here today for domestic products as well as exports.

Ultimately, it is the level of product reliability a company wants to achieve that matters. To meet the new global standard, manufacturers must have a set of Electrical Insulation Materials (EIMs) that are pre-tested and obtain system recognition before proceeding to end-product testing and certification. Companies can also use an EIS databank as a reference to develop more reliable electrical winding for other non-regulated applications.
