This standard BS EN 61788-9:2005 Superconductivity is classified in these ICS categories:
17.220.20 Measurement of electrical and magnetic quantities
17.220.01 Electricity. Magnetism. General aspects
29.050 Superconductivity and conducting materials
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.
