Annotation of standard text IEC 61788-13-ed.2.0 :
IEC 61788-13:2012 describes considerations for the measurement of hysteretic loss in Cu/Nb-Ti multifilamentary composites using DC- or low-ramp-rate magnetometry. This international standard specifies a method of the measurement of hysteretic loss in multifilamentary Cu/Nb-Ti composite conductors. Measurements are assumed to be on round wires with temperatures at or near 4,2 K. DC or low-ramp-rate magnetometry will be performed using either a superconducting quantum interference device or a vibrating-sample magnetometer. Extension to the measurement of superconductors in general is given in Annex. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. Modifications made to the second edition extend to the measurement of superconductors in general, in various sample sizes and shapes, and at temperatures other than 4,2 K, and use the word "uncertainty" for all quantitative statistical expressions to eliminate the quantitative use of "precision" and "accuracy". La CEI 61788-13:2012 decrit des elements necessaires pour mesurer les pertes par hysteresis dans les composites multifilamentaires de Cu/Nb-Ti au moyen dun magnetometre a courant continu ou a faible vitesse de rampe. La presente norme internationale specifie une methode de mesure des pertes par hysteresis dans les conducteurs composites multifilamentaires de Cu/Nb-Ti. On suppose que les mesures sont effectuees sur des fils ronds a des temperatures egales ou proches de 4,2 K. La magnetometrie en courant continu ou a faible vitesse de rampe sera effectuee au moyen dun interferometre quantique supraconducteur ou dun magnetometre a echantillon vibrant. Lextension a la mesure des supraconducteurs en general est donnee en Annexe. Cette deuxieme edition annule et remplace la premiere edition parue en 2003. Cette edition constitue une revision technique. Les modifications apportees a la deuxieme edition sont une extension a la mesure des supraconducteurs en general, de tailles et formes dechantillons diverses et a des temperatures differentes de 4,2 K, et le remplacement par le mot "incertitude" pour toutes les expressions statistiques quantitatives utilisant les termes "precision" et "exactitude".
