We have a print with "measurements without tolerance, specification according to DIN 6930 m". I cannot find this standard. Does anyone know what it is or where I can find it? Thank you.
No, I don't have any of those DIN standards. I am in the business of calibrating electronic test and measuring equipment, so they don't apply. I haven't looked, but you can probalby buy that from ANSI as well.jager said:Thanks. One of our engineers ordered DIN 6930 and now we find we also need DIN 6935, just for angular tolerance of formed metal. Yes, I am in metal stamping. We produce small metal stampings for automotve and electrical, plus a few other businesses. Do you have DIN 6935? Thanks.
As a matter of curiosity, I'm prompted to ask:jager said:We ordered it yesterday. To find the tolerance on formed angles, we had to spend $78! At least we have it now for future reference. Thanks for the reply.

Same here. I see the DIN 6930 2 standard (from the link provided above), but don't see DIN 6930 M, as called out on our print.
Our spec on file is DIN 6930 Part 2, Steel Stampings General Tolerances - which correlates to what is offered on the DIN website.
Any ideas what that M denotes? Thanks in advance!
(as a side note, it ocurred to me that Germany seems to be under-represented on the cove. just an observation.)
(Emphasis added).This standard is intended to simplofy [sic] drawings. It specifies general tolerances on linear and angular dimensions and on coaxiality and symmetry in four accuracy grades comprising f (fine), m (medium), g (coarse), and sg (very coarse). When selecting a defined accuracy grade, the respective workshop accuracy is to be taken into account. If smaller tolerances are required or if larger tolerances are permitted and more economical, these shall be indicated adjacent to the relevant basic size. General tolerances as specified in this standard intended for use cold and hot stampings made from steel flat products. They shall apply whenever reference is made to this standard on drawings or relevant documents (e.g. in delivery conditions).
