I checked the website and didn't find it yet.  In my copy of the C4.4 recommended practices for heat shaping and straightening, the temp. conversions in section four are erroneous.  It says 180 degrees F. equals 100 degrees C.  I think someone did the T x 9/5 but didn't add 32.  For over a dollar a page, I would expect a little better proofreading from AWS.
