Elementi sistema za zaščito pred strelo (LPSC) - 4. del: Zahteve za pritrdilne elemente (IEC 62561-4:2023)

Standard IEC 62561-4:2023 je na voljo kot IEC 62561-4:2023 RLV, ki vsebuje mednarodni standard in njegovo različico z revizijami, ki prikazujejo vse spremembe tehnične vsebine v primerjavi s prejšnjo izdajo. Standard IEC 62561-4:2023 obravnava zahteve in preskuse za kovinske ter nekovinske pritrdilne elemente, ki se uporabljajo za ohranitev in podporo lovilnega, odvodnega ter ozemljitvenega sistema. Tretja izdaja razveljavlja in nadomešča drugo izdajo, objavljeno leta 2017. Ta izdaja je tehnično popravljena izdaja. Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
a) uskladitev z najnovejšo izdajo standarda ISO IEC 60068-2-52:2017 v zvezi s preskusom v atmosferi s slano meglo;
b) uskladitev z novo izdajo standarda ISO 22479:2019 v zvezi s preskusom v vlažni žveplasti atmosferi;
c) nov normativni dodatek v zvezi z uporabnostjo prejšnjih preskusov.
