To the best of my knowledge, no, although there may be something. The 
IPC was originally the Institute of Printed Circuits, even though it 
changed its name (twice). I don't think there is an Institute of 
Electronic Components or similar that could act as the motive power 
behind standardisation. Arguably more important than contamination 
levels (cleanliness is too abstract as a meaningful term), is 
solderability: are there any norms for that?

I brought up the subject in my book and developed some instruments that 
could measure the ionic contamination on a single diode and sold a 
smallish number of them (perhaps about 20) but most component 
manufacturers were not interested: in the 1980s, they were often using 
very aggressive water-soluble fluxes for tinning DIL Kovar lead frames 
and often "cleaned" them by dipping in the same bath for days or weeks 
on end. That "cleaning" water was often almost as strong as the flux 
itself!!!!
