Method of measurement of bending dimensions

Total length of bar (L) measured along centre line





A +B +C +(E) 0.5r d
Neither A nor (E) shall be less than P in Table 2. See Note 1. 



A +B +C +(D)r 2d
Neither A nor (D) shall be less than P in Table 2. See Note 1. 



A +B +C +D +(E) 2r 4d
Neither A nor (E) shall be less than P in Table 2.


May also be used for a flag link viz:




A +B +C +D +(E) 2r 4d
Neither A nor (E) shall be less than P in Table 2. 



A +2B +C +(E)
Neither A nor (E) shall be less than P in Table 2.
See Note 1. 



2A +B +2C +1.5r 3d
(C) and (D) shall be equal and not more than A nor less than P in Table 2.


Where (C) and (D) are to be minimized the following formula may be used:
L = 2A + B + max(21d, 240)




2(A +B +(C)) 2.5r 5d
(C) and (D) shall be equal and not more than A or B nor less than P in Table 2.


Where (C) and (D) are to be minimized the following formula may be used:
L = 2A + 2B + max(16d, 160)




A +B +C +(D) +2(E) 2.5r 5d
(E) and (F) shall be equal and not more than B or C, nor less than P in Table 2.




2A +3B +2(C) 3r 6d
(C) and (D) shall be equal and not more than A or B nor less than P in Table 2.


Where (C) and (D) are to be minimized the following formula may be used:
L = 2A + 3B + max(14d, 150)




A +B +C +2D +E +(F) 3r 6d
Neither A nor (F) shall be less than P in Table 2. See Note 2.




A
See clause 10.




π(A  d) + B
Where B is the lap.




Cπ(Ad)
C = number of turns


Where B is greater than A/5 this equation no longer applies, in which case the following formula may be used: L = C((π(A d))^{2} + B^{2})^{0.5}




A +2B +C + (D) 2r 4d
Isometric sketch
Neither C or (D) shall e less than P in Table 2.



All other shapes

To be calculated
See Note 2.


Where standard shapes cannot be used.
No other shape code number, form of designation or abbreviation shall be used in scheduling.
A dimensioned 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 dimension shall allow for tolerance.
