IEC 62305-4:2010 PROTECTION AGAINST LIGHTNING -Part 4: Electrical and electronic systems within structures
1 Scope
This part of IEC 62305 provides information for the design，installation，inspection,maintenance and testing of electrical and electronic system protection(SPM) to reduce therisk of permanent failures due to lightning electromagnetic impulse (LEMP) within a structure.
This standard does not cover protection against electromagnetic interference due to lightning,which may cause malfunctioning of internal systems.However,the information reported inAnnex A can also be used to evaluate such disturbances.Protection measures againstelectromagnetic interference are covered in lEC 60364-4-44 11 1 and in the lEC 61000 series[2]
This standard provides guidelines for cooperation between the designer of the electrical andelectronic system, and the designer of the protection measures, in an attempt to achieveoptimum protection effectiveness.
This standard does not deal with detailed design of the electrical and electronic systemsthemselves.
