Source notes and corrections
gost:angleIu: The printed Iu values are approximately ten times lower than both A*ru^2 and Ix+Iy-Iv from the same rows. The comparison manufacturer's catalog lists 12200 and 14700 cm4 with matching dimensions, area, mass, Ix and Iv. Adopt the explicitly authorized catalog values, not recalculated values from rounded inputs.
Original source value: 1220
Verified value: 12200
