BS EN 61788-5 is a European Standard on superconductivity which is the fifth part of multi-series that covers a test method for the determination of copper to superconductor volume ratio of Cu/Nb-Ti composite superconducting wires.
This test method is carried out by dissolving the copper with nitric acid. Deviations from this test method that are allowed for routine tests and other specific restrictions are given in this BS EN 61788-5.
Note: The test method given in this BS EN 61788-5 is expected to apply to other superconducting composite wires after some appropriate modifications.
BS EN 61788-5 on copper to superconductor volume ratio is relevant to:
The copper to superconductor volume ratio of composite superconductors is used mainly to calculate the critical current density of superconducting wires. The test with the method given in BS EN 61788-5 may be used to provide part of the information needed to to determine the suitability of a specific superconductor.
BS EN 61788-5 provides principles, preparation of chemicals, apparatus, measurement procedure, calculation of results, the uncertainty of the test method, and test reports.
Moreover, the standardized terminology provided by BS EN 61788-5 can eliminate confusion and ambiguity amidst entities involved with superconductors.
Overall BS EN 61788-5 can provide high efficiency, sensitivity, and reliability of the product, At ambient pressure, copper superconductors are the highest temperature superconductors known as energy-saving so it would result in tremendous energy savings compared with the technology we have today.
