BS 8666:2005 Standard Shapes
All shapes where standard shapes cannot be used.No other shape code number, form of designation or abbreviation shall beused 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 forpermissible deviations shall be indicated in parenthesis, otherwise thefabricator is free to choose which dimension shall allow for the tolerance.

NotesThe length equations for shape codes47, 51 and 63 are for when dimensionsC and D are to be minimised.
'+ max(14 d, 150)' means add the greatervalue of either 14 d or 150mm.
