Thought I would bump this since there have been no new entries in almost a year.

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

Here is a ГОСТ (National standard) for straight edges:

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

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:
