Rubber — Reinforced styrene-butadiene latex — Determination of total bound styrene content
Covers two methods for latices which are reinforced with polystyrene or copolymer of butadiene and styren. The two methods, the carbon/hydrogen method and the nitration method, give comparable results although they differ in principle. Either method may be used, according to preference. A table and five figures contain more details. - Constitutes a minor revision of the first edition (ISO 4655-…

Hardmetals — Determination of total carbon content — Gravimetric method
This second edition cancels and replaces the first edition (i.e. ISO 3908:1976). The method is applicable to some carbides, mixtures of these carbides and binder, all grades of presintered or sintered hardmetals, produced from these carbides, having an insoluble carbon content between 0,02 and 0,5 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and…
