Hi Andrew, all
there is a ∆B metric (introduced in ISO 15937) and a table with typical values / categories (no, low, moderate, normal, high). There is high correlation between ∆B and ∆CIEb* (CIEb* measured with M1 - CIEb* measured with M2) if you can't measure ∆B directly (some measurement device such as FD7 support it already).
you can find more at my last presentation I gave at ISO WG3: http://www.fogra.org/en/fogra-publications/pub-talks/presentations-prepress/...

We are currently working on FOGRA52 which reflects uncoated stock with typical (high) amount of OBA
Begging the question, what's typical (and high) amouts of OBA and what does one do when the paper in question doesn't match? It's a significant issue considering the vast amount of papers available and their amout of OBAs.
