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.

ISO 20764:2003(E)
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 20764 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.

INTERNATIONAL STANDARD ISO 20764:2003(E)

Petroleum and related products — Preparation of a test portion
of high-boiling liquids for the determination of water content —
Nitrogen purge method
WARNING — The use of this International Standard may involve hazardous materials, operations and
equipment. This International Standard does not purport to address all of the safety problems
associated with its use. It is the responsibility of the user of this International Standard to establish
appropriate safety and health practices and determine the applicability of regulatory limitations prior
to use.
1 Scope
This International Standard specifies two procedures for the preparation of test portions from petroleum and
related products boiling above 200 °C, 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 (see [1]
in the Bibliography) and ISO 12937 (see [2] in the Bibliography).
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Principle
3.1 Atmospheric pressure
The water is driven out of a weighed portion of the material under test by a nitrogen purge at 120 °C. It is then
condensed in methanol (4.2) held in a titration vessel (5.4) at approximately − 77 °C. The resulting
water/methanol solution is immediately available for the determination of water content by Karl Fischer titration.
