雷対策の関連規格

雷防護に関する国際規格(IEC、ITU-T)と国内規格(JIS)

国内規格

JIS(日本工業規格Japanese Industrial Standards)は、原則的に貿易障壁をなくす目的でIEC (国際電気標準会議 International Electrotechnical Commission)規格を翻訳した一致規格(IDT)として発行されています。但し、我国の状況と合わない場合では下線点線付き文書の追加又は編集(MOD)が許されています。

国際規格(IEC、ITU-T)

IECはITU(国際電気通信連合International Telecommunication Union)、IEEE(米国電気電子学会Institute of electrical and Electronics Engineers)などの国際機関と緊密に連携し活動しています。
