Specification for solventless polymerisable resinous compounds used for electrical insulation; part 2: methods of test; test methods for coating powders for electrical purposes

This document specifies the procedural requirements for conducting testing on electrically insulating powder coatings applied via solvent-free polymerizable resin systems. It functions as the second segment within a broader series dedicated to defining performance characteristics and evaluation protocols for such materials. The content focuses exclusively on the methodologies utilized to assess the physical and electrical properties of the coating powders when subjected to various operational conditions and stress factors. Detailed instructions are provided regarding sample preparation, equipment calibration, environmental controls, and the step-by-step execution of measurements. These procedures ensure consistency and reliability in data acquisition across different testing facilities. The approach covers a range of critical parameters relevant to the durability and insulating capacity of the finished product. By adhering to these defined methods, manufacturers and testing laboratories can generate comparable results essential for quality assurance and technical compliance within the electrical equipment sector. The scope extends to covering specific interactions between the coating material and the substrate, as well as the effects of processing variables on the final film structure.
