IEC

International Electrotechnical Comission

The IEC Standards for thermoset composites are developed by a team of experts (currently six) from the UK, Austria, Germany, France, the Netherlands, and the United States.

They are the most current and up to date standards for industrial laminates in the world. A Norplex-Micarta employee is the current U.S. delegate and Convener (chairman) of the Working Group (IEC TC15 WG-6).

It is the job of the Working Group to write standards for the thermoset composites listed below.

Sheets – IEC 60893-1, 2, 3 & 4TR. – “Insulating Materials – Industrial Rigid Laminated Sheets Based on Thermosetting Resins for Electrical Purposes.”

Round Rolled Tubes & Rods – IEC 61212-1, 2 & 3. – “Insulating Materials – Industrial Rigid Round Laminated Tubes and Rods Based on Thermosetting Resins for Electrical Purposes.”

Molded Tubes and Rods (rectangular and hexagonal)– IEC 62011-1, 2 & 3. – “Insulating Materials – Industrial Rigid, Molded, Laminated Tubes and Rods of Rectangular and Hexagonal Cross-Section, Based on Thermosetting Resins for Electrical Purposes.”

While most materials have been tested to IEC standards, some evaluation may still be in process. Please refer to the Technical Data Bulletin or contact us for assistance in determining if the grade you would like can be certed to an IEC standard.
