Product testing and certification. The total length shall be given a 10d for bzr material; and, unless there is an end anchorage bend or hook, b 12d for grade material not exceeding sizes one bending dimension, preferably an end of 20 mm; dimension, shall be indicated in parentheses as the free dimension to allow for the permissible c 14d for grade material in sizes of 25 mm deviations.

BSSpecification for production and installation. To avoid separate equations for each steel grade and bending radius, simplified total length formulae are used for shape beending 61, 77, 78, 79 and For bending and rebending on site refer to BS The tolerances given in Table 4 also apply.

If a shape that is given in this Table 1 is required but a different dimension is to allow for the permissible deviations, the shape shall be drawn out and given the shape code 99 and the free dimension shall be indicated schedul parentheses. Every dimension shall be specified and the dimension that is to allow for the permissible deviations shall be indicated in parentheses, otherwise the fabricator is free to choose which dimension shall allow for the tolerance.

It should be borne in mind that special precautions such as reducing the speed of bending or increasing the radius of bending may necessary in cold weather. The purpose of this standard is to ensure uniformity of practice in the scheduling of steel for the reinforcement of concrete. Where r is greater than the minimum value in table 3 BSuse shape code Enquiries as to the availability of third party certification schemes and of competent test laboratories will be forwarded by BSI to the Association of 446 Bodies.

The smaller bendjng bar size the more 44466 is the effect of the negative cutting tolerance, and this fact was considered when deciding on the length given in Table 3 and the formulae given in Table 1 and Table 2.

NOTE Unless A is small relative to d, this shape is fabricated in a closed form and pulled to shape on site. Various BSI electronic information services are also available which give details on all its products and services.
