IACS URs is a catalogue on this site: 41 calculators sit under it, each covering one entry in the scheme. This page is the index that explains what the scheme is for, how an entry is read, and where the boundaries of the classification fall.
It is a stub. The full article will set out the governing instrument, the structure of the catalogue, and the decisions a reader has to make before picking an entry, because choosing the wrong entry is the common failure and it is rarely obvious from the entry itself.
