After 22 years, the NEMA LI 1 (R1998) standard has been replaced by an improved standard called ANSI/NEMA IM 60000-2021 Industrial Laminated Thermosetting Products.

The new edition of the industrial laminate thermoset standard (ANSI/NEMA IM 60000-2021 ) is now in effect as of February 4th, 2022. Let us help you understand the new changes!

Tune in & listen to one of the authors Solomon Chiang, who chairs the ANSI/NEMA Industrial Laminate Advisory Technical Committee, talk about what’s new and the critical updates. Not only are we the insulation experts, but we helped write the standard. Solomon is also The Gund Company’s Director of Corporate Research and Development.

This new edition covers the manufacture, testing, and performance of laminated thermosetting products in the form of sheets, rods, and tubes. It also includes a new format that consolidates the requirements for the physical and electrical properties of the individual NEMA Grades.  It was developed by the NEMA Insulating Material Section and is published as an American National Standard. The new edition carries the tradition of adding new material grades to reflect the current and future needs of the industry. It also includes SI units (International System) for international audiences and compares to other international Standards. The new edition clarifies some potential ambiguities in the previous version to make it more user-friendly.

Webinar topics will include:

  • Composite Insulations and NEMA Standards for Industrial Thermoset Laminates
  • Types of Thermoset Resin and Substrate (Fiber) Used in NEMA Grades
  • Properties of Thermoset Laminates
  • Product Performance Optimization with NEMA Grades
  • New NEMA Grades, G-12, G-13, G-15 and GPO-5
  • Thermoset Laminate Processing Methods
