Petroleum and related products - Preparation of a test portion of high-boiling liquids for the determination of water content - Nitrogen purge method (ISO 20764:2003)

ISO 20764:2003 specifies two procedures for the preparation of test portions from petroleum and related products boiling above 200 degrees Celsius, which can then be used for the determination of total water content within the range of 3 mg/kg to 1 000 mg/kg. The method is applicable to unused and used lubricating oils, non-aqueous hydraulic fluids and high-boiling solvents. The test portions generated by these procedures are suitable for standard Karl Fischer water-content determinations, such as those described in ISO 6296 and ISO 12937.

Mineralölerzeugnisse und verwandte Produkte - Herstellung eines Probenteiles von hochsiedenden Flüssigkeiten für die Bestimmung des Wassergehaltes - Verfahren mit Stickstoff-Spülung (ISO 20764:2003)

Diese Internationale Norm legt zwei Verfahren zur Herstellung von Probenteilen von Erdöl und verwandten Produkten, die bei mehr als 200 °C sieden, fest. Die Probenteile können dann für die Bestimmung des Gesamtwassergehaltes im Bereich vom 3 mg/kg bis 1000 mg/kg verwendet werden. Dieses Verfahren ist auf gebrauchte und ungebrauchte Schmieröle, nichtwässrige Druckflüssigkeiten und hochsiedende Lösungsmittel anwendbar. Die Probenteile, die mit diesen Verfahren erzeugt werden, sind für standardmäßige Bestimmungen des Wassergehaltes nach Karl Fischer wie z.B. für diejenige Bestimmungen geeignet, die in ISO 6296 (siehe [1] im Literaturverzeichnis) oder ISO 12937 (siehe [2] im Literatur-verzeichnis) beschrieben sind.

Pétrole et produits connexes - Préparation d'une prise d'essai de liquides à haut point d'ébullition en vue du dosage de l'eau - Méthode par purge à l'azote (ISO 20764:2003)

L'ISO 20764:2003 spécifie deux méthodes permettant la préparation de prises d'essai à partir de pétrole et de produits connexes distillant au-dessus de 200 degrés Celsius. Celles-ci peuvent alors faire l'objet d'une détermination de leur teneur totale en eau dans la plage comprise entre 3 mg/kg et 1 000 mg/kg. La méthode est applicable à la fois aux huiles lubrifiantes neuves et usagées, aux fluides hydrauliques non aqueux et aux solvants de haut point d'ébullition. Les prises d'essai obtenues au moyen de ces méthodes conviennent pour la détermination de leur teneur en eau par une méthode de Karl Fischer standard, telle que celle décrite dans l'ISO 6296 ou dans l'ISO 12937.
