Essentially, those are two codified mappings of 
the ISO 9:

- one (Table A) strives to be universal and 
provides 1:1 mapping for all glyphs of 
Cyrillic-using languages; consequently it uses 
lots of "unusual" (e.g., rarely included in 
popular fonts) diacritics; I do not vouch for 
the *completeness* of the set *being mapped*, 
though;

- another (Table B) takes into consideration the 
phonologies of languages and uses the reduced 
set of target Latin glyphs; mappings are 
specific for each language; e.g., Belarusian Г 
is H, however Russian Г is G.

Can't answer more specifically without ISO copy 
at hand.

BTW, provisions of ISO 9 were introduced into 
inter-state GOST series 7 (bibliographical 
information).
