This part of IEC 62607 provides a standardized test method for the measurement of contact and coating resistivity of nano-enabled electrode materials. This method will enable a customer to:

  1. decide whether or not a coating composite material is usable, and

  2. select best combinations of coating composite material with fabrication technologies suitable for their application.

This part of IEC 62607 includes:

  • definitions of terminology used in this part of IEC 62607,

  • recommendations for sample preparation,

  • outlines of the experimental procedures used to measure and calculate the contact and coating resistivity,

  • methods of interpretation of results and discussion of data analysis, and

  • a case study.
