AWWA C207-13 Steel Pipe Flanges for Waterworks Service

Major Revisions

18. The format of Table 5, AWWA blind-flange thickness, was revised for consistency,
and the footnotes were updated and expanded

Have they changed the actual blind thinkness or just how they are dimensionsed?

I'm not buying the new standard for a table layout change!

Has anybody got the 2013 edition

Thanks
