Superconductivity - Part 13: AC loss measurements - Magnetometer methods for hysteresis loss in superconducting multifilamentary composites

Superconductivity - Part 13: AC loss measurements - Magnetometer methods for hysteresis loss in superconducting multifilamentary composites

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'.

Supraconductivité - Partie 13: Mesure des pertes en courant alternatif - Méthodes de mesure par magnétomètre des pertes par hystérésis dans les composites multifilamentaires supraconducteurs

La CEI 61788-13:2012 décrit des éléments nécessaires pour mesurer les pertes par hystérésis dans les composites multifilamentaires de Cu/Nb-Ti au moyen d'un magnétomètre à courant continu ou à faible vitesse de rampe. La présente norme internationale spécifie une méthode de mesure des pertes par hystérésis dans les conducteurs composites multifilamentaires de Cu/Nb-Ti. On suppose que les mesures sont effectuées sur des fils ronds à des températures égales ou proches de 4,2 K. La magnétométrie en courant continu ou à faible vitesse de rampe sera effectuée au moyen d'un interféromètre quantique supraconducteur ou d'un magnétomètre à échantillon vibrant. L'extension à la mesure des supraconducteurs en général est donnée en Annexe. Cette deuxième édition annule et remplace la première édition parue en 2003. Cette édition constitue une révision technique. Les modifications apportées à la deuxième édition sont une extension à la mesure des supraconducteurs en général, de tailles et formes d'échantillons diverses et à des températures différentes de 4,2 K, et le remplacement par le mot 'incertitude' pour toutes les expressions statistiques quantitatives utilisant les termes 'précision' et 'exactitude'.

Supraprevodnost - 13. del: Meritve izgub pri izmeničnem toku - Metode z magnetometrom za histerezne izgube v supraprevodnih večvlakenskih kompozitih

Ta del standarda IEC 61788 opisuje dejavnike, ki jih je treba upoštevati pri meritvah histereznih izgub v Cu/Nb-Ti večvlakenskih kompozitih z uporabo izmeničnega toka ali magnetometrije z nizko stopnjo rampe. Ta mednarodni standard določa metodo za meritve histereznih izgub v večvlakenskih Cu/Nb-Ti kompozitnih prevodnikih. Predvideva se, da so meritve opravljene na okroglih žicah s temperaturo približno ali točno 4,2 K. Magnetometrija z izmeničnim tokom ali nizko stopnjo rampe bo izvedena z uporabo superprevodne kvantne interferenčne naprave (SQUID magnetometer, glej dodatek A) ali magnetometrom s tresočim vzorcem (VSM). V primeru, da so razlike med rezultati kalibriranih magnetometrov, bodo upoštevani rezultati magnetometra s tresočim vzorcem, ki so ekstrapolirani na nični stopnji rampe. Dodatek splošnim meritvam superprevodnikov je podan v dodatku B.

Superconductivity - Part 2: Critical current measurement - DC critical current of Nb3Sn composite superconductors
SIST EN 61788-2:2008

This part of IEC 61788 covers a test method for the determination of the d.c. critical current of Nb3Sn composite superconductors which are fabricated by either the bronze process or the internal tin diffusion process and have a copper/non-copper ratio larger than 0,2. This method is intended for use with superconductors which have critical currents of less than 1 000 A and n-values larger than 12 under standard test conditions and at magnetic fields of less than or equal to 0,7 times the upper critical magnetic field. The test specimen is immersed in a liquid helium bath at a known temperature during testing. The Nb3Sn composite test conductor has a monolithic structure with a total round-cross-sectional area that is less than 2 mm2. The specimen geometry used in this test method is an inductively coiled specimen. Deviations from this test method which are allowed for routine tests and other specific restrictions are given in this standard. Nb3Sn conductors with critical currents above 1 000 A or total cross-sectional areas greater than 2 mm2 can be measured with the present method with an anticipated reduction in precision and a more significant self-field effect (see Annex C). Other, more specialized, specimen test geometries may be more appropriate for larger conductor testing which have been omitted from this present standard for simplicity and to retain precision. The test method given in this standard should in principle apply to Nb3Sn composite wires fabricated by any other process. This method is also expected to apply to other superconducting composite wires after some appropriate modifications.

Superconductivity - Part 1: Critical current measurement - DC critical current of Nb-Ti composite superconductors
SIST EN 61788-1:2008

This part of IEC 61788 covers a test method for the determination of the d.c. critical current of either Cu/Nb-Ti composite superconductors that have a copper/superconductor ratio larger than 1 or Cu/Cu-Ni/Nb-Ti wires that have a copper/superconductor ratio larger than 0,9 and a copper alloy (Cu-Ni)/superconductor ratio larger than 0,2, where the diameter of Nb-Ti superconducting filaments is larger than 1 micrometre. The changes for the Cu/Cu-Ni/Nb-Ti are described in Annex C. The Cu-Ni uses all of the main part of the standard with the exceptions listed in Annex C that replace (and in some cases are counter to) some of the steps inthe main text. This method is intended for use with superconductors that have critical currents less than 1 000 A and n-values larger than 12, under standard test conditions and at magnetic fields less than or equal to 0,7 of the upper critical magnetic field. The test specimen is immersed in a liquid helium bath at a known temperature during testing. The test conductor has a monolithic structure with a round or rectangular cross-sectional area that is less than 2 mm2. The specimen geometry used in this test method is an inductively coiled specimen. Deviations from this test method that are allowed for routine tests and other specific restrictions are given in this standard. Test conductors with critical currents above 1 000 A or cross-sectional areas greater than 2 mm2 could be measured with the present method with an anticipated increase in uncertainty and a more significant self-field effect (see Annex B). Other, more specialized, specimen test geometries may be more appropriate for larger conductor testing which have been omitted from this present standard for simplicity and to retain a lower uncertainty. The test method given in this standard is expected to apply to other superconducting composite wires after some appropriate modifications.

Superconductivity - Part 3: Critical current measurement - DC critical current of Ag- and/or Ag alloy-sheathed Bi-2212 and Bi-2223 oxide superconductors
SIST EN 61788-3:2007

This part of IEC 61788 covers a test method for the determination of the dc critical current of short and straight Ag- and/or Ag alloy-sheathed Bi-2212 and Bi-2223 oxide superconductors that have a monolithic structure and a shape of round wire or flat or square tape containing mono- or multicores of oxides. This method is intended for use with superconductors that have critical currents less than 500 A and n-values larger than 5. The test is carried out with and without an applying external magnetic field. For all tests in a magnetic field, the magnetic field is perpendicular to the length of the specimen. In the test of a tape specimen in a magnetic field, the magnetic field is parallel or perpendicular to the wider tape surface (or one surface if square). The test specimen is immersed either in a liquid helium bath or a liquid nitrogen bath during testing. Deviations from this test method that are allowed for routine tests and other specific restrictions are given in this standard.
