This Indian Standard was adopted by the Inclinn Standards Institution on 21 September 1963, after the draft finalized by the joint SLctiolrnl Committee for Concrete lieinforctment lrnd been approvc~tl by the Building Division Council and th[* Structnral and Mdals Di\,ision Council. This standard is prepared with a view to assisting dcsigncrs, cnginc~s and contractors in drawing up precise bcntling schedules for reinforcement used in reinforced concrete construction, and also in the fising of rcinforccment. Though, it is well appreciated that much of time and effort can bc saved on the site if rational dimensions for shaping the bars are supplied to the bar benders; different practices have been followed hitherto in drawing up the bar bending schedule. It is attempted in this standard to unify the various practices followed and to rationalize the bending schcdulc to correspond with metric scrics of rcinforcemcnt. Rar bending is an operation which requires adequate -supervision, skilled workmanship and cffic’ent equipment; and any attempt to carry out the work with unskilled la b our and inefficient tools will undoubtedly result in unsatisfactory work. In view of this, certain recommended methods of bar bending are also included in this standard. Though. this standard is primarily intended for the preparation of bending schedule for reinforced concrete work, it may also be generally adopted for mild steel reinforcement used in prestresscd concrete work. The Sectional Committee responsible for the preparation of this standard has taken into consideration the views of producers, consumers and technologists and has related the standard to the manufacturing and trade practices followed in the country in this,field. Due weightage has also been given to the need for international co-ordination among standards prevailing in different countries of the world. These considerations led the Committee to derive assistance from the following Publications: DRAFT REVISION OF B.S. 1478: 1948 BENDING DIMENSIONSA ND SCHEDULINGO F BARS FOR THE REINFORCEMENOTF CONCRETE. British Standards Institution. AC1 315-1951 MANUAL OF STANDARD PRAC-CICE FOR DETAILING REINFORCED CONCRETE STRUCTURES. American Concrete Institute. Wherever a reference to any Indian Standard appears in this code, it shall be taken as a reference to its latest version. This standard is intended chiefly to cover the technical provisions relating to bending and fixing of bars for concrete reinforcement, and it does not include all the necessary provisions of a contract.
