This part of this European standard specifies tolerances on shape dimensions and mass of hot-rolled structural steel equal and unequal leg angles. The sizes of these angles are given in EN 10056-1. These tolerances do not apply to equal and unequal leg angles produced from stainless steel. Note: until EN 10056-1 is published, either Euronorms 56 and 57 or the corresponding national standards may be used.
