This International Standard specifies a method for the
determination of the KOH number of natural rubber
latex concentrate which is preserved wholly or in part
with ammonia. The method is applicable to latices
containing boric acid. The method is not applicable to
latices preserved with potassium hydroxide. It is not
necessarily suitable for latices from natural sources
other than Hevea brasiliensis, or for latices of syn-
thetic rubber, compounded latex, vulcanized latex or
artificial dispersions of rubber.
