Describes photometric methods for determining manganese, after oxidation with sodium periodate, in rubbers and rubber latices. Divided into two sections, the first describes a method for compounded or vulcanized rubbers which do not contain chlorine and secondly 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. Can be applied to natural and synthetic rubbers which do not contain chlorine. Covers references, principle, reagents, apparatus, sampling, procedure, expression of results and test report.
