Rubber and rubber latices. Determination of manganese content. Sodium periodate photometric methods Ingestion-build-183098 Identify existing standards applicable to1 Scope This International Standard specifies photometric methods for the determination of manganese, after oxidation with sodium periodate, in rubbers and rubber latices. Both methods contain provisions for analysis of chlorine containing rubber. Clause 3 specifies a method for compounded or vulcanized rubbers which is not affected by heavy loadings of fillers such as synthetic and natural silicates or calcium carbonates in various forms, or by the
