This part of IEC 62305 provides information for the design, installation, inspection,
maintenance and testing of a LEMP protection measures system (LPMS) for electrical and
electronic systems within a structure, able to reduce the risk of permanent failures due to
lightning electromagnetic impulse.
This standard does not cover protection against electromagnetic interference due to lightning,
which may cause malfunctioning of electronic systems. However, the information reported in
Annex A can also be used to evaluate such disturbances. Protection measures against
electromagnetic interference are covered in IEC 60364-4-44 and in the IEC 61000 series [1]2.
This standard provides guidelines for cooperation between the designer of the electrical and
electronic system, and the designer of the protection measures, in an attempt to achieve
optimum protection effectiveness.
This standard does not deal with detailed design of the electrical and electronic systems
themselves.
