ISO/TC 17/SC 16/WG 7 - Reinforcing bars

This document specifies technical requirements for ribbed bars to be used as reinforcement in concrete. It is applicable to steel delivered in the form of bars, coils and de-coiled products. This document covers both weldable and non-weldable steels. It does not apply to ribbed bars produced from finished products, such as plates and railway rails. The production process is at the discretion of the manufacturer.

ISO 6935-1:2007 specifies technical requirements for plain bars to be used as reinforcement in concrete. ISO 6935-1:2007 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 ISO 6935-1:2007 apply to straightened product. The steel grades are designated with steel names allocated in accordance with ISO/TS 4949:2003. ISO 6935-1:2007 covers products delivered in straight lengths. Plain bars produced from finished products, such as plates and railway rails, are excluded.

ISO 6935-2:2015 specifies technical requirements for ribbed bars to be used as reinforcement in concrete. ISO 6935-2:2015 is applicable to steel delivered in the form of bars, coils and de-coiled products. It includes both weldable and non-weldable steels. The production process is at the discretion of the manufacturer. It is not applicable to ribbed bars produced from finished products, such as plates and railway rails.

ISO 6935-2:2007 specifies technical requirements for ribbed bars to be used as reinforcement in concrete. ISO 6935-2:2007 covers ten steel grades not intended for welding which are B300A-R, B300B-R, B300C-R, B300D-R, B400A-R, B400B-R, B400C-R, B500A-R, B500B-R and B500C-R, and eleven steel grades intended for welding which are B300DWR, B350DWR, B400AWR, B400BWR, B400CWR, B400DWR, B420DWR, B500AWR, B500BWR, B500CWR and B500DWR. The steel grades are designated with steel names allocated in accordance with ISO/TS 4949:2003. ISO 6935-2:2007 covers products delivered in straight lengths. The production process is at the discretion of the manufacturer. Ribbed bars produced from finished products, such as plates and railway rails, are excluded.
