BAR SHAPE CODES TO BS 8666:2005 clear Click here
for Tables
  Shape Code 99
All other shapes where standard shapes cannot be used.

No other shape code number, form of designation or abbreviation shall be used in scheduling.

A dimensional sketch shall be drawn over the dimension columns A to E. Every dimension shall be specified and the dimension that is to allow for permissible deviations shall be indicated in parenthesis, otherwise the fabricator is free to choose which dimensions shall allow for tolerance.

To be calculated - See Note 2.
  The values for minimum radius and end projection, r and P respectively, as specified in Table 2, shall apply to all shape codes (see 7.6).

The dimensions in parenthesis are the free dimensions. If a shape given in this table is required but a different dimension is to allow for the possible deviations, the shape shall be drawn out and given the shape code 99 and the free dimension shall be indicated in parenthesis.

The length of straight between two bends shall be at least 4d, see figure 6.

Figures 4, 5 and 6 should be used in the interpretation of bending dimensions.

NOTE 1 The length equations for shape codes 14, 15, 25, 26, 27, 28, 29, 34, 35, 36 and 46 are approximate and where the bend angle is greater than 45º, the length should be calculated more accurately allowing for the difference between the specified overall dimensions and the true length measured along the central axis of the bar. When the bending angles approach 90º, it is preferable to specify shape code 99 with a fully dimensional sketch.

NOTE 2 Five bends or more might be impractical within permitted tolerances.

NOTE 3 For shapes with straight and curved lengths (e.g. shape codes 12, 13, 22, 33 and 47) the largest practical mandrel size for the production of a continuous curve is 400mm. See also Clause 10.
