IEC 60455-2:2015 specifies methods of test to be used for testing resin based reactive compounds, their components and cured compounds used for electrical insulation. This third edition cancels and replaces the second edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – Introduction of test methods related to IEC 60455-3-8; – Additional and updated test methods for resins. Keywords: resin based reactive compounds used for electrical insulation
