This International Standard recommends procedures to
be used for obtaining, by automatic means, representative
samples of crude oil and liquid Petroleum products being conveyed
by Pipeline.
NOTE - Although throughout this International Standard the term
crude oil is used, this should be taken to include other Petroleum
liquids where the technique and equipment are also applicable.
This International Standard does not apply to the sampling of liquefied Petroleum gases and liquefied natura1 gases.
The principal purpose of this International Standard is to give guidelines for specifying, testing, operating, maintaining
and monitoring crude oil Samplers.
The sampling procedures for crude oil are intended to provide representative samples for the determination of
a) the oil composition and quality;
b) the total water content;
c) other contaminants that are not considered to be part
of the crude oil transferred.
If the sampling procedures for a),
separate samples may be required.
b) and c) are in conflict,
NOTE - The results of the laboratory analysis may be used for
calculating adjustments to the declared quantity of crude oil transferred.
The procedure for carrying out the adjustments does not form
part of this International Standard.
Sample handling is included, covering all aspects following
collection to the transfer of the Sample to laboratory
apparatus.
This International Standard describes the practices and procedures believed at the present time to be the most likely to lead to representative sampling and hence to accurate water determination. However, the accuracy of the water determination on Pipeline samples obtained using automatic Samplers will depend upon the arrangement and characteristics of all the various elements making up the sampling System, and on the accuracy of the subsequent analytical procedures.

Diese ÖNORM empfiehlt ein Probenahme-Verfahren für Rohöl und flüssige Erdölprodukte, die mit Rohrleitungen gefördert werden. Sie gilt nicht für Flüssiggas und verflüssigtes Erdgas. Der prinzipielle Zweck ist die Angabe von Richtlinien für die Festlegung, Prüfung, den Betrieb, die Behandlung und Überwachung von Rohölproben.
