钢筋混凝土用钢.第1部分:光面钢筋

[中文适用范围]： ISO 6935 的本部分规定了用作混凝土钢筋的光面钢筋的技术要求。ISO 6935 的本部分涵盖九种非焊接钢筋等级，即 B240A-P、B240B-P、B240C-P、B240D-P、B300A-P、B300B-P、B300C-P、B300D-P 和 B420D-P，以及一种焊接钢筋等级 B420DWP。生产工艺由制造商决定。它也适用于以卷材形式供应的光面钢筋。ISO 6935 的本部分的要求适用于拉直产品。钢筋等级的指定钢名按照 ISO/TS 4949 分配。注：第一个“B”代表钢筋混凝土用钢。接下来的 3 位数字代表规定的上屈服强度特征值。第五个字母代表延展性等级 (4.4)。下一个符号与焊接有关；“-”表示不适用于焊接，“W”表示适用于焊接。最后一个“P”代表光棒。ISO 6935 的这一部分涵盖以直条形式交付的产品。不包括由成品（例如钢板和铁路钢轨）生产的光棒。 [外文原描述]： 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.
