Petroleum liquids - Manual sampling (ISO 3170:2004)
ISO 3170:2004 specifies the manual methods to be used for obtaining samples of liquid or semi-liquid hydrocarbons, tank residues and deposits from fixed tanks, railcars, road vehicles, ships and barges, drums and cans, or from liquids being pumped in pipelines.
ISO 3170:2004 applies to the sampling of petroleum products, crude oils and intermediate products, which are stored in tanks at or near atmospheric pressure, or transferred by pipelines, and are handled as liquids at temperatures from near ambient up to 200 degrees Celsius.
The sampling procedures specified are not intended for the sampling of special petroleum products which are the subject of other International Standards, such as electrical insulating oils (IEC 60475), liquefied petroleum gases (ISO 4257), liquefied natural gases (ISO 8943) and gaseous natural gases (ISO 10715).
Flüssige Mineralölerzeugnisse - Manuelle Probenahme (ISO 3170:2004)
Diese Internationale Norm legt die manuellen Verfahren fest, die anzuwenden sind, um Proben von flüssigen oder halb-flüssigen Kohlenwasserstoffen, Tankrückständen und Ablagerungen aus feststehenden Tanks, Eisenbahnkesselwagen, Straßentankwagen, Schiffen und Lastkähnen, Fässern und Kanistern oder aus Flüssigkeiten, die durch Rohrleitungen gepumpt werden, zu gewinnen.
Die Norm bezieht sich auf die Probenahme von Mineralölerzeugnissen, Rohölen und Zwischenprodukten, welche in Tanks bei oder nahe bei Atmosphärendruck gelagert oder die durch Rohrleitungen gefördert werden und welche bei Temperaturen von etwa Umgebungstemperatur bis zu 200 °C als Flüssigkeiten vorliegen.
Die hier beschriebenen Verfahren zur Probenahme gelten nicht für die Probenahme von speziellen Mineralölerzeugnissen, die anderen Normen unterliegen, wie beispielsweise Isolieröle (IEC 60475), Flüssiggase (ISO 4257), verflüssigtes Erdgas (ISO 8943) und gasförmige Erdgase (ISO 10715).
Diese Internationale Norm bezieht sich auf existierende Probenahmeverfahren und gebräuchliche Ausrüstungen. Es ist jedoch nicht beabsichtigt, den Gebrauch von neuerer Ausrüstung, die noch nicht für die allgemeine Anwendung entwickelt wurde, auszuschließen, vorausgesetzt, dass solche Ausrüstungen eine Probenahme in Übereinstimmung mit den Anforderungen und Verfahren dieser Internationalen Norm ermöglichen.
ANMERKUNG Für den Zweck dieser Internationalen Norm darf das Symbol % (m/m) verwendet werden, um Massenanteile in Prozent auszudrücken.
Produits pétroliers liquides - Echantillonnage manuel (ISO 3170:2004)
L'ISO 3170:2004 spécifie les méthodes manuelles de prélèvement à employer en vue d'obtenir des échantillons d'hydrocarbures liquides ou semi-liquides, de résidus et de dépôts contenus dans des réservoirs fixes, des wagons-citernes, des camions-citernes, des navires-citernes, des chalands, des fûts et des bidons, ou de liquides en cours de pompage dans des oléoducs.
L'ISO 3170:2004 s'applique à l'échantillonnage de produits pétroliers, de pétroles bruts et de produits intermédiaires, stockés dans des réservoirs à la pression atmosphérique ou approchante, ou acheminés par oléoduc, et qui sont manutentionnés à l'état liquide à des températures allant d'une température voisine de celle ambiante à 200 °C.
Les méthodes d'échantillonnage spécifiées ne concernent pas certains produits pétroliers qui font l'objet d'autres Normes internationales, tels que les huiles diélectriques (CEI 60475), les gaz de pétrole liquéfiés (ISO 4257), les gaz naturels liquéfiés (ISO 8943) et à l'état gazeux (ISO 10715).

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 3170 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants,
Subcommittee SC 3, Static petroleum measurement.
This third edition cancels and replaces the second edition (ISO 3170:1988), which has been technically
revised.
The principal technical changes include the addition of
procedures for tank sampling under restricted and closed system conditions, and
procedures for the taking of manual spot samples from pipelines containing high vapour pressure liquids.

ISO 3170:2004(E)
Introduction
This International Standard may be applied in combination with ISO 3171.
The purpose of this International Standard is to standardize conditions for obtaining a sample of liquid/semi-
liquid hydrocarbons from a tank, drum or pipeline by manual means. If the hydrocarbon to be sampled is of
non-homogeneous character showing significant variations in composition or containing sediments and water,
samples taken manually should not be expected to be representative, but may enable the degree of non-
homogeneity to be assessed and estimates of quality and quantity to be made.
Procedures are specified which minimize or eliminate losses of light ends from samples. Such losses can
occur during handling or transfer of samples, thereby making them non-representative of the bulk.
The procedures specified are intended to provide samples for the following purposes:
a) the determination of the liquid/hydrocarbon quality;
b) the determination of the water content;
c) the determination of other contaminants that are not considered to be part of the liquid transferred.
If the sampling conditions for purposes a), b) and c) are in conflict, separate samples are required.
Sampling procedures for tank contents that are not homogeneous are specified that enable the degree of non-
homogeneity to be assessed and estimates of quality and quantity to be made.
Procedures for the tank sampling of liquid hydrocarbons under inert gas pressure are included, together with
techniques for sampling from tanks which are equipped with vapour emission control systems.
It is recognized that, in many countries, some or all of the items covered by this International Standard are the
subject of mandatory regulations imposed by the laws of those countries. In cases of conflict between such
mandatory regulations and this International Standard, the former prevail.
