IEC 60664-3:2016(E) is available as \/2 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60664-3:2016 applies to assemblies protected against pollution by the use of coating, potting or moulding, thus allowing a reduction of clearance and creepage distances as described in IEC 60664-1. This document describes the requirements and test procedures for two methods of protection: – type 1 protection improves the microenvironment of the parts under the protection; – type 2 protection is considered to be similar to solid insulation. This edition includes the following significant technical changes with respect to the previous edition: a) information added concerning interpolation; b) provided scratch test is only for type 2 protection; c) renumbered the scratch test to follow the visual examination test, since it makes more sense there; d) separated the tables under what is now called Annex A, to make them clearer. It has the status of a basic safety publication in accordance with \/2<\/p>\n
