Natural gas - Determination of sulfur compounds - Determination of total sulfur by oxidative microcoulometry method (ISO 16960:2014)

ISO 16960:2014 specifies a method for the determination of total sulfur in the range from 1 mg/m3 to 200 mg/m3 in pipeline natural gas by oxidative microcoulometry. Natural gas with sulfur contents above 200 mg/m3 can be analysed after dilution with a suitable sulfur-free solvent.

Erdgas - Bestimmung von Schwefelverbindungen - Bestimmung des Schwefelgehalts mittels oxidativem mikrocoulometrischen Verfahren (ISO 16960:2014)

Diese Internationale Norm legt ein Verfahren fest, um mit Hilfe der oxidativen Mikrocoulometrie den Schwefelgehalt im Bereich von 1 mg/m3 bis 200 mg/m3 in Erdgas aus Pipelines zu bestimmen. Erdgas mit Schwefelgehalten über 200 mg/m3 kann nach Verdünnen mit einem geeigneten schwefelfreien Lösemittel ebenfalls untersucht werden.

Gaz naturel - Détermination des composés soufrés - Détermination de la teneur totale en soufre par microcoulométrie oxydante (ISO 16960:2014)

L'ISO 16960:2014 spécifie une méthode de détermination de la teneur totale en soufre dans la plage de 1 mg/m3 à 200 mg/m3 dans les canalisations de gaz naturel par microcoulométrie oxydante. Le gaz naturel avec des teneurs en soufre supérieures à 200 mg/m3 peut être analysé après dilution appropriée avec un solvant exempt de soufre.

Zemeljski plin - Določevanje žveplovih spojin - Določevanje celotnega žvepla z oksidativno mikrokulometrično metodo (ISO 16960:2014)

Ta mednarodni standard določa metodo za določevanje celotnega žvepla v razponu od
1 mg/m3 do 200 mg/m3 v cevovodu zemeljskega plina z oksidativno mikrokulometrijo. Zemeljski plin z vsebnostjo
žvepla nad 200 mg/m3 je mogoče analizirati po redčenju z primernim topilom brez žvepla.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established 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.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.
