The IPC-2222 table of contents shows that "Thermal Relief in Conductor Planes" gets only one tenth of a page. I can't imagine any detailed information in that space. It's sister document, IPC-2221, can be found for free at http://www.victronics.cl/Inf_tecnica/Notas%20de%20aplicacion/PCBs/IPC-2221(L).pdf . IPC-2221 has a section on thermal relief, but without any useful details.
