ASSESSMENT OF THE RISK OF DAMAGE DUE TO LIGHTNING (IEC 61662 : 1995, IDT)
This Malaysian Standard specifies the procedure for evaluation of the risk of damage to a structure caused by direct and indirect lightning flashes, and to permit the bodies concerned to fix an acceptable value for the frequency of damage to structures. Once an upper limit for the frequency of damage has been fixed, the procedure given allows for the selection of appropriate protective measures for the structure.
NOTE — Damage to the equipment due to direct magnetic coupling with lightning current which strikes the earth nearby the structure may be usually disregarded. Where sensitive electronic equipment are installed in the structure, this damage should be also taken into account in the assessment of the risk.
