Selecting the Right Certification Option for EIS

An electrical insulation system (EIS) comprises a specific combination of materials verified for chemical compatibility when used at certain maximum temperatures. These combinations form systems such as those used in motors, transformers and solenoids. If you work in the electrical insulation systems industry, testing and certification can help you verify that individual insulation materials can perform safely in shared environments in complex electrical systems.

To create reliable, high-performance EISs, manufacturers must use quality electrical insulation materials (EIMs) and EISs and thoroughly review them when building magnetic devices such as motors, transformers, generators and solenoids. Today’s material shortages require manufacturers’ flexibility in their use of materials. Watch UL’s complimentary three-session webinar series to deepen your understanding of certification standards and evaluation of EIS safety and performance so you can explore your options when you face materials shortages.

• EIS adoption
• Substitution or modification of an EIS
• Short-term test
• Chemical compatibility test (CCT)
• Thermal aging
