How does ISO 2768-mk apply to diameter tol?

What are you asking?

ISO2768 applies to dimensions which do not have an individual tolerance indication like "linear dimensions (e.g. external sizes, internal sizes, step sizes, diameters, radii, distances, external radii and chamfer heights for broken edges)".

The 'm' specifies a medium tolerance range.


"Wildfires are dangerous, hard to control, and economically catastrophic."

Here is my issue I have a print that specifies to use ISO 2768-mk for dimensions without tolerances. Then they give the 'm' equivalents on the bottom of the print for all of the lengths and the angles. The only info I need is there is a diameter without a tolerance range, Ø6 mm, what tolerance would I give that?
 
I got it sorry I was thinking linear was only for length dimensions and my print calls for 'm' linear and 'k' for all other GD. Thanks for letting me know, my brain is running slow this mornig.
 
There are 4 different tolerance grades for linear dimensions, yours is 'medium/m'

The Ø6 is a linear 6 dimension and thus can be looked up in the tables.

The 'K' denotes a certain GD&T grade, this second letter has no relation to tolerances - only to GD&T.
 
Well, except that the 'T' in GD&T stands for tolerance;-).

I take it from your last post you found your answer ljsanders85, if not there are excerpts of this standard, or at least it's DIN predecessor on the web.
