Railway applications - Insulation coordination -- Part 1: Basic requirements - Clearances and creepage distances for all electrical and electronic equipment

The whole document deals with insulation coordination in railways. It applies to equipment for use in signalling, rolling stock and fixed installations up to 2000 m above sea level. Insulation coordination is concerned with the selection, dimensioning and correlation of insulation both within and between items of equipment. In dimensioning insulation, electrical stresses and environmental conditions are taken into account. For the same conditions and stresses these dimensions are the same. OneAn objective of insulation coordination is to avoid unnecessary overdimensioning of insulation. This standard specifies: ? requirements for clearances and creepage distances for equipment; ? general requirements for tests pertaining to insulation coordination. The term equipment relates to a section as defined in 1.3.1.3: it may apply to a system, a sub-system, an apparatus, a part of an apparatus, or a physical realisation of an equipotential line. This standard does not deal with : ? distances through solid or liquid insulation; ? distances through gases other than air; ? distances
