ISO 6935-1:2007 PDF

Scope: This part of ISO 6935 specifies technical requirements for plain bars to be used as reinforcement in concrete. This part of ISO 6935 covers nine steel grades not intended for welding which are B240A-P, B240B-P, B240C-P, B240D-P, B300A-P, B300B-P, B300C-P, B300D-P and B420D-P, and one steel grade intended for welding which is B420DWP. The production process is at the discretion of the manufacturer. It also applies to plain bars supplied in coil form. The requirements of this part of ISO 6935 apply to straightened product. The steel grades are designated with steel names allocated in accordance with ISO/TS 4949. NOTE The first “B” stands for steel for reinforcing concrete. The next 3 digits represent the specified characteristic value of upper yield strength. The fifth letter stands for ductility class (4.4). The next symbol relates to welding; “-” means not intended for welding and “W” means intended for welding. The last “P” stands for plain bar. This part of ISO 6935 covers products delivered in straight lengths. Plain bars produced from finished products, such as plates and railway rails, are excluded.
