Recorded Webinar - Polymeric Materials – Insulation Systems


UL Knowledge Services together with the National Electrical Manufacturers Association (NEMA) is pleased to bring you a webinar on Polymeric Materials - Insulation Systems.  The issuance of IEC 60085, and it’s subsequent reference in many other IEC-based UL harmonized standards, has left many companies confused as to how to comply with the requirements of IEC 60085. The standard has requirements for both individual Electrical Insulating Materials (EIM) and Electrical Insulation Systems (EIS). What relationship exists between an EIM and an EIS? Can a specific application utilize a material that functions as both? UL, the industry leader in standards development, is available to help you understand the requirements in this new standard. Ensure your low-voltage control gear is compliant with the requirements in IEC 60085, as they apply to UL Standards. Come away from our webinar with a deeper and increased knowledge of EIM and EIS, and how they are utilized in UL 508, UL 60947-1 and 60947-4-1A. Get your critical conformity assessment questions answered by standards experts from UL, the leaders in standards development.

The topics covered in this workshop are:

  • What is an Electrical Insulation System, and how is it evaluated?
  • What is an Electrical Insulating Material, and how is it evaluated?
  • Temperature ratings of Electrical Insulating Materials and Electrical Insulation Systems
  • Materials used as both an Electrical Insulating Material and a component of an Electrical Insulation System
  • Adoption and use of Electrical Insulation Systems
  • Comparison of UL 1446 and IEC 60085 temperature ratings

Existing Knowledge Requirements:

Participants should have a basic understanding of UL 508 polymeric material requirements, especially those related to the use of insulation systems. Participants should also possess a general understanding of insulation systems as they are used in motors, coils, and valves.
