Defines photometric procedures for determining the manganese content, following oxidation with sodium periodate, in rubbers and rubber latices. Both these procedures contain provisions for analysing chlorine-containing rubber.

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.

Clause3 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 presence of compounding ingredients which form an insoluble phosphate under the conditions of the test.

Clause4 specifies a method for raw and compounded natural and synthetic rubbers and latices which do not contain heavy loadings (more than about 10%) of inert silicate fillers or any ingredient such as titanium dioxide which under the conditions of test will form an insoluble phosphate.
