I need to clarify my question. I'm looking at a drawing that has the statement "TOLERANCES ARE PER: DIN ISO 2678-FK". As I understand it, the F refers to Class f (fine) linear and angular dimensions and the K refers to form, such as position, flatness, perpendicularity, etc. These form...
Simple question, does the "Ranges in nominal lengths in mm" for position refer the feature size, for instance, hole diameter, or does it refer to the distance between features?
