( After "an ears of a%%lication of E-E standards in Euro%e &the first

standard for E-E/ NF C 17102 standard has een %ulished in 1334' and

worldwide it has een decided to revise the three standards fro" France

-%ain and Portugal in a %arallel %rocedure ased on a Franco-%anish

wor!ing grou% that has een followed carefull Portugal. ,his NFC C 17102/2011 standard is now a%%roved in France and at the ti"e of writing the

%a%er the -%anish standard 5NE 2116/2011 has 8ust %assed the national

%ulic en9uir and is going to e %ulished a%%ro:i"atel in two wee!s and

Portugal standard NP;;22 is on the a%%roval %rocedure.

( =igh voltage laorator research has een a %owerful tool forlightning research in the last decades although toda it has eenso"ehow forgotten co"%ared to other research activities such as

natural lightning "easure"ents or theoretical "odeling. #n theother hand standard testing of lightning %rotection co"%onents canonl e %erfor"ed at =igh Joltage laorator facilities at %resent.,here is no standard test of lightning %rotection %erfor"ance undernatural lightning conditions. ,he advantage of a laorator is thattesting %ara"eters such as a%%lied voltage or current a"ient

conditions and geo"etrical configuration can e controlled.

( Kesides testing at a high voltage laorator %rovides a statisticallsignificant a"ount of data. #viousl natural lightning conditionscannot e full achieved at a high voltage laorator ut so"e%ara"eters can e fairl re%roduced. Although lightning is a large

scale %heno"enon laorator tests offer a good o%%ortunit to testand %erfor" research aout lightning %rotection. +n this %a%er wewill %resent two "ain i"%ortant laorator testing arrange"ents anda su""ar of the standards %rocedure.
