Superconductivity - Part 9: Measurements for bulk high temperature superconductors - Trapped flux density of large grain oxide superconductors

Specifies a test method for the determination of the trapped field (trapped flux density) of bulk high temperature superconductors. This International Standard is applicable to large grain bulk oxide superconductors that have well defined shapes such as round discs, rectangular, and hexagonal pellets. The trapped flux density can be assessed at temperatures from 4,2 K to 90 K. For the purpose of standardization, the trapped flux density will be reported for liquid nitrogen temperature.

Supraconductivité - Partie 9: Mesures pour supraconducteurs haute température massifs - Densité de flux résiduel des oxydes supraconducteurs à gros grains

Spécifie une méthode d'essai pour la détermination du champ résiduel (densité de flux résiduel) des supraconducteurs haute température massifs. La présente Norme internationale s'applique aux oxydes supraconducteurs à gros grains ayant des formes bien définies telles que les disques et les pastilles rectangulaires et hexagonales. La densité de flux résiduel peut être déterminée pour des températures comprises entre 4,2 K et 90 K. Pour les besoins de la normalisation, la densité de flux résiduel sera consignée pour la température de l'azote liquide.

This European Standard was approved by CENELEC on 2005-06-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.
