TITLE: Looking for organisations promoting standard notation in mathematics
QUESTION [5 upvotes]: Sometimes, I would like—in order to be as coherent and comprehensible as possible in the notation I use—to follow recommendations from some international working group, committee,  or organisation devoted to develop and promote standard mathematical language, similar to  IUPAC for chemistry or  IUPAP for physics.
Do you know if such thing exists for mathematics?

REPLY [2 votes]: The ISO has published a document ISO/DIS 80000-2 whose contents list can be viewed here. Unfortunately the full document is behind a paywall.
