Plastics - Unsaturated polyesters and epoxide resins - Determination of total chlorine content (ISO 4615:1979)

Specification of two methods for the determination of chlorine: Oxidation of the test portion with sodium peroxide (method A) in a Parr bomb or with gaseous oxygen (method B) in a flask, followed by electrometric or volumetric titration of the resulting chlorides. Blank tests shall be carried out by using the same quanities of reagents as in the determination.

Kunststoffe - Ungesättigte Polyester und Epoxidharze - Bestimmung des Gesamtchlorgehaltes (ISO 4615:1979)

Diese Internationale Norm legt zwei Verfahren zur Bestimmung des Gesamtchlor- gehaltes in ungesättigten Polyestern und Epoxidharzen fest, nämlich: Verfahren A: Aufschluß in einer Verbrennungsbombe; Verfahren B: Aufschluß im Erlenmeyerkolben.

Plastiques - Résines de polyesters non saturés et époxydes - Détermination de la teneur totale en chlore (ISO 4615:1979)

La présente Norme internationale spécifie deux méthodes de dosage du chlore total dans les résines de polyesters non saturés et époxydes, à savoir :  - méthode A combustion dans une bombe ;  - méthode B combustion dans un ballon.  
NOTES  1 La détermination de la teneur en chlore et brome combinés, ou de la teneur en brome seulement, est également possible par ces méthodes. Le mode opératoire approprié doit faire l'objet d'un accord entre 1 "acheteur et le vendeur".  2 Ces méthodes ne sont pas applicables au dosage du chlore total dans les résines époxydes contenant du chlore comme impureté.

ISO (the International Organization for Standardization) is a worldwide federation
of national Standards institutes (ISO member bodies). The work of developing
International Standards is carried out through ISO technical committees. Every
member body interested in a subject for which a technical committee has been set
up has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated
to the member bodies for approval before their acceptance as International
Standards by the ISO Council.
International Standard ISO 4615 was developed by Technical Committee
ISO/TC 61, Plastics, and was circulated to the member bodies in August 1978.
lt has been approved by the member bodies of the following countries :
South Africa, Rep. of
Austria Hungary
Belgium Iran Sweden
