Lindsay, Southwire)

  14. Recommendations from TC90 discussed at IEC Sector Board 1 meeting in 2007 Beijing & 2008 Newcastle • TC90 should construct liaison relations with related TCs in IEC to deal with superconducting power equipments, for examples, power cables with TC20 and others • TC90 should make a communication with SB1 on market needs for superconducting power equipments in transmission and distribution area • TC90 will proceed with standardization works for superconducting properties, such as long high temperature superconducting wire properties, and superconducting devices based upon its activities IEC Sector Board 1: Transmission and distribution

  22. IEC/TC90:現在までのまとめと今後 現在までの国際規格発行：測定方法14件(TC90)および超電導関連用語1件(TC1：用語＋TC90)←日本からの提案が大多数 IEC規格作成のノウハウが各WGのConvenorやWGエキスパートの間に定着するには、10年かかった→人脈形成、国際標準制定までの各国との落としどころ協議→標準作成のフォーマット Pre-standard活動として実施された先進国間の協力であるVAMAS *の成果をIEC規格へ取り込んできた（*先進材料と標準におけるベルサイユサミットの合意）－外部との連携が重要 将来方針の合意を常に形成する努力が必要 EU諸国からの国の代表は、同じ会社の異なる国の代表として出席する場合もある。規格が機器ﾚﾍﾞﾙになり利害が衝突するようになると、日本としては、票を多く取りにくい。→中国、韓国との連携など重要 超電導のように、産業として成熟していない分野は、国の積極的な関与が不可欠（受益者負担の考えだけでは難かしい）
