Iso 2768 Fh Hole Tolerance
I realize that this has been discussed here a few times before, but I could use some additional help.
Working for a very global oriented company, we use ISO for all Global Dimensioning and Tolerancing standards for our drawings. After receiving training per the ASME Y14.5 standard, it has been a constant state of confusion for me while trying to understand our standard tolerancing schemes that we have on our prints.
Time and time again I have seen prints that outright conflict with ASME, and most often they lack very important controls, and sometimes datums, to insure proper function of the parts. Every time I question or comment about this, I am always told that our general tolerance callout of ISO 2768 covers anything not stated. Now I have never been trained per ISO and I have had a difficult time finding training, in the US, for the many documents that make up the ISO Geometrical Product Specifications (GPS).
Recently, there has been a push to provide further development to our Design Engineers and Technical Drawers in the area of making and understanding drawings made to the ISO standards. As a result, we have been watching internal training videos on the subject matter. This is where my
While I expected some slight differences, like ISO Concentricity is very similarly used as ASME Position, I was absolutely SHOCKED when I got to the short training video on the „General Tolerances' portion of ISO 8015 and 2768. I took some screen captures of the example shown by the video. So can any of the experts here tell me their $0.02 on this matter?
Has as anyone here actually been formally trained to the ISO standard? We are starting to really push towards sourcing parts to new suppliers in countries not accustomed to DIN/ISO, and I am not certain that we will all be speaking the same engineering „Language'.

- The tolerances work in such a way that for a hole H7 means that the hole should be made slightly larger than the base dimension (in this case for an ISO fit 10+0.015−0, meaning that it may be up to 0.015 mm larger than the base dimension, and 0 mm smaller).

Is the M6 hole tolerance also 25mm? Cashew 1.4 for macos. If so, it would be -4 / -17 By the way, DIN 2768mk is a general tolerance table that provides the tolerances for anything that is not toleranced on the drawing, it does not refer to the diameter tolerances you are asking about.
