Where special end sequence of columns shall be maintained. Details and advice can be obtained from the Copyright Manager. Contact the Information Centre. The total length shall be given a 10d for grade material; and, unless bsr is an end anchorage bend or hook, b 12d for grade material scheduls 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.

Copyright Copyright subsists in all BSI publications. If a different dimension is required to be the free variable, the shape shall be drawn and given the shape code Shape Code 65 A These bars will be supplied straight when the radius is greater than that given in table 5 of BS There shall be at least two full turns in the helix. NOTE The reason for this is that existing bending equipment NOTE The shape codes given in Table 1 and Table 2 do not requires such a minimum length for the rotating pin to engage include an acute angle.


No conclusions type and size given on the schedule see 4. In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested.

Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service. To avoid separate equations for each steel grade and bending radius, simplified total length formulae are used for shape codes 61, 77, 78, 79 and Table 2 gives other shape codes longer than 2 mm. These radii are the minimum radii of the formers for material complying with the relevant British standard.

Various BSI electronic information services are also available which give details on all its products and services. NOTE 2 See clause 8 for definition of y. Before taking into account the cumulative cutting tolerances, the nominal value for y in Table 3 shall be calculated as follows: BSQuality systems1. BSI also holds the 4646, in the UK, of the publications of the international standardization bodies. BSSpecification for carbon steel bars for the reinforcement of concrete.


Total length of bar L measured along centre line. Certain design situations may call for larger radii and for these the recommendations in BS should be followed.

Figure 4 shows an example of a bar label, which 6. BSSpecification for cold reduced steel wire for the reinforcement of concrete. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 18, an inside back cover and a back cover. Users of British Standards are responsible for their correct application.

These formulae are necessarily approximate.

BSSpecification for sizes of paper and board. If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained.

In giving this length on the schedule, due consideration should be given to the When dimensioning an acute angle the tangential possibility of negative cutting tolerances up to 25 mm reducing lines shown in Figure 5 shall be used.
