This Standard specifies the dimensions, mass and their tolerances of hot rolled steel
sections as well as the appearance, shapes and permissible variations thereof. The scope
of this Standard and the choice of specified items in this Standard shall be specified in respective product standards or upon the agreement between the purchaser and the supplier.
Unless otherwise specified, the text of this Standard shall be spplied, however, Annexes masy be applied in place of hte text upon hte agreement between the pruchaser and the supplier.
