PDF of This Tip
By
getting up to speed on the 2009 revision of Y14.5
you will learn of the changes which:
- Add new concepts
and symbols to clarify the meaning of the
drawing
- Clarify concepts
found in the 1994 Standard
- Extend
principles found in the 1994 Standard
- Resolve
differences or discrepancies found in the
current Standard
- Incorporate
concepts from other Y14 standards
- Reference
Y14.41, the standard that nables the tolerancing
of 3-D models and reduced dimension drawings

In addition to the 7 new symbols
we now have a way to override datum precedence. There are
new categories of features such as irregular features of
size, continuous and complex features. There are new
tolerance zone definitions and new ways to apply old
symbols.
There is way too much to cover in a Tip. So, my tip to you
is—contact Tec-Ease, Inc., to get updated to the new
revision of the Y14.5 standard through our seminars,
computer based training, on-line training and of course our
books, pocket guide and wall chart.
We also offer the new revision of the Standard in an
electronic form that keeps the text and graphics together
and has extensive link and search capabilities. It is titled
The Y14.5 Standard-Ease® 2009. You can learn more at
