How are my peers addressing DCOF, which standard are you using, ANSI A326.3-17 issued in Jan 2018?
Also can someone explain how DCOF is measured?
This is probably the best explanation that I have found of the AcuTest which is the basis for A137.1 and A326.3: https://www.tcnatile.com/images/pdfs/IntroducingDCOFAcuTest.pdf.
