Specifies the minimum quality requirements and the corresponding methods of test for six grades of raw natural rubber. A table delivers the maximum dirt content and some other characteristics for these grades.
Steel and iron — Determination of total carbon content — Infrared absorption method after combustion...
The method is applicable to carbon contents between 0,003% (m/m) and 4,5 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. The annexes give additional information on the international co-operative tests, a graphical representation of precision data and features of induction furnaces and carbon analysers.

A test portion is dissolved in ethanol and the solution is acidified. The alkane monosulfonic acids are separated from the alkane disulfonates and sulfate ions by extraction with light petroleum. The light petroleum phase is evaporated and the residue is solved in ethanol. Traces of alkali are removed by means of a cation-exchange column. The eluate is neutralized with carbonate-free sodium…
