Insulation coordination for equipment within low-voltage systems - Comprehensive method for determining clearances and creepage distances equal to or less than 2 mm Ingestion-build-64721 c) The specifications for materials1 Scope and object This part of IEC 60664 specifies the dimensioning of clearances and creepage distances for spacings equal to or less than 2 mm for printed wiring board and equivalent constructions, where the clearance and the creepage distance are identical and are along the surface of solid insulation, such as the paths described in 6. 2 of Part 12 (Examples 1, 5 and 11). The dimensioning in this standard is more precise than that provided by Part
