Describes photometric methods for the determination of manganese, after oxidation with sodium periodate, in rubbers and rubber latices. Section one specifies a method for compounded or vulcanized rubbers which do not contain chlorine. Section two specifies a method for raw rubber, latex and compounded rubber which does not contain heavy loadings of inert silicate fillers or any ingredient such as titanium dioxide which under the conditions of test will form an insoluble phosphate.
