They are not literally defined in the specification, although I believe all letters from this specification are derived from Fit Tolerancing Charts ISO General tolerances for symmetry. General tolerances for linear measures and level squares with four tolerance classes are useful for simplifying drawings. This tolerance principles says that no opposite relation between measure, form and position tolerance exists principle of superposition. Skruvar standard Enligt ritning.

Please enter a title.
So, in -2 you'll see that K is a tolerance class Steve. General tolerances for linear measures and level squares with four tolerance classes are useful for simplifying drawings.
If smaller tolerances are needed or bigger ones are more economical, io these tolerances are indicated next to the nominal size. If smaller tolerances are needed or bigger are more economical these tolerances should be mentioned directly according to ISO Each chart is divided into three classes of tolerances as follows: For nominal sizes below 0,5 mm the limit measures are to be indicated directly at the nominal measure.
General tolerances for form and position should be used while the tolerance principle according. Please type your message and try again. This tolerance principles says that no opposite relation between measure, form and position tolerance exists isk of superposition. General tolerances for form and position are valid for form elements for which form and position tolerances are not indicated individually.
Skruvar standard Enligt ritning. By choosing a special tolerance class exactly the precision level common in workshops should be taken into account.
Range of specified size in mm. Doug, Just to add to what Steve has already mentioned: It is starting to become a little clearer as to what impact this standard has on the way we manufacture I would hate for us to have our work rejected because we chose to ignore the tolerances. H, K and L.
Tabular 1 Limits for linear measures. Right now I am assuming the fin stands for medium, and I have no idea on the "K" Thanks in advance.
ISO mK | SOLIDWORKS Forums
Doug, there are 2 parts to ISO On our metric drawings we ieo ISO m K. Go to original post. If general tolerances according to ISO are valid, the following has to be inserted in the title box, i.
Greetings all Can someone please tell me what the mK means? DIN ISO is for simplifying drawing and fixes general tolerances in three tolerance classes for form and position.
Thanks Steve and Eddie Thanks for the info. Tabular 2 Limit measures for radius of curvature and chamfer height.
lso Bei Nennmassen unter 0,5 mm sind die Grenzabmasse direkt am Nennmass anzugeben. By choosing the tolerance class precision levels common in workshops should be taken into account.
