Cliff:

Here was my original comment and your response:

===================================================
BB wrote:

I'm not sure it's safe to assume that a three place decimal is
automatically a tolerance of +/- .005, even IF it's very common. Our
satellite part prints call for +/- .002 on all three place dimensions,
we also have a medical customer that requires +/- .001 on three place
decimals, and then we have another customer that allows +/- .010 for
three place dims.
There doesn't seem to be any industry wide standard for this, or
at
least none that everyone adheres to.

Cliff's reply:

In the US, "shall be in accordance with ANSI Y14.1 unless otherwise
specified" is fairly typical.
======================================================

It certainly sounded like your were claiming that ANSI Y14.1 spelled
out the standards for three place decimals. Otherwise why even mention
it at all?
