This is an open thread. Anybody can contribute to it, and I encourage you to do so.

Thanks.

See 2-nd and 3-rd tables.
2nd table for thin edges ЛД, ЛТ и ЛЧ - linearity tolerance
3rd table for wide straight edges: 2nd coulumn - flatness , 3rd - parallelism.

For squares

Thanks to the poster for that info.

If there is a better or easier one than this then just delete this post.

I've sometimes wondered about the perverse nature of 'gauge' measurements, where larger numbers mean smaller measurements! This page explains the fascinating history behind the gauge system for wire and sheet metal measurements:

And this is a handy reference for sheet gauges in various metals:
