Petroleum products and related products - Determination of kinematic viscosity - Method by Stabinger type viscometer (ISO/FDIS 23581:2024)

Petroleum products and related products - Determination of kinematic viscosity - Method by Stabinger type viscometer (ISO/FDIS 23581:2024)

This document specifies a procedure for the determination of kinematic viscosity (ν) by calculation from dynamic viscosity (η) and density (ρ) of both transparent and opaque liquid petroleum products and crude oils using the Stabinger type viscometer.
The result obtained using the procedure described in this document depends on the rheological behaviour of the sample. This document is predominantly applicable to liquids whose shear stress and shear rate are proportional (Newtonian flow behaviour). If the viscosity changes significantly with the shear rate, comparison with other measuring methods is not possible except at similar shear rates.
The precision has been determined only for the materials, density ranges and temperatures described in Clause 13. The test method may be applied to a wider range of viscosity, density, temperature and materials. The precision and bias may not be applicable for materials not listed in Clause 13.

Mineralölerzeugnisse und verwandte Produkte - Bestimmung der dynamischen Viskosität und Berechnung der kinematischen Viskosität - Verfahren mit dem Viskosimeter nach dem Stabinger-Prinzip (ISO/FDIS 23581:2024)

Dieses Dokument legt ein Verfahren fest, in dem die kinematische Viskosität (ν) von sowohl durchsichtigen als auch undurchsichtigen flüssigen Mineralölerzeugnissen und Mineralölen unter Verwendung eines Viskosimeters nach dem Stabinger-Prinzip bestimmt wird, die kinematische Viskosität wird dabei durch Berechnung aus der dynamischen Viskosität (η) und der Dichte (ρ) ermittelt.
Das unter Anwendung des in diesem Dokument beschriebenen Verfahrens erzielte Ergebnis ist vom Fließverhalten der Probe abhängig. Dieses Dokument ist hauptsächlich auf Flüssigkeiten anwendbar, deren Schubspannung und Schergeschwindigkeit proportional sind (Newtonsches Fließverhalten). Ändert sich die Viskosität signifikant mit der Schergeschwindigkeit, ist der Vergleich mit anderen Messverfahren nicht möglich mit Ausnahme bei ähnlichen Schergeschwindigkeiten.
Die Präzision wurde nur für die in Abschnitt 13 beschriebenen Materialien, Dichtebereiche und Temperaturen bestimmt. Das Prüfverfahren kann auf einen breiteren Bereich von Viskosität, Dichte, Temperatur und Materialien angewendet werden. Es ist möglich, dass die Präzision und die systematische Abweichung auf Materialien anwendbar sind, die nicht in Abschnitt 13 aufgeführt sind.
WARNUNG — Die Anwendung dieses Dokuments kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Dieses Dokument beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieses Dokuments, vor der Anwendung dieses Dokuments geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz des Personals zu ergreifen, und die Geltung weiterer diesbezüglicher Auflagen zu prüfen.

Petroleum products - Determination of aromatic hydrocarbon types in middle distillates - High performance liquid chromatography method with refractive index detection
SIST EN 12916:2024

This document specifies a test method for the determination of the content of mono-aromatic, di aromatic and tri+-aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates.
This document specifies two procedures, A and B.
Procedure A is applicable to diesel fuels that may contain fatty acid methyl esters (FAME) up to 30 % (V/V) (as in [1], [2] or [3]) and petroleum distillates in the boiling range from 150 °C to 400 °C (as in [4].
Procedure B is applicable to paraffinic diesel fuels with up to 7 % (V/V) FAME. This procedure does not contain a dilution of the sample in order to determine the low levels of aromatic components in these fuels.
The polycyclic aromatic hydrocarbons content is calculated from the sum of di-aromatic and tri+-aromatic hydrocarbons and the total content of aromatic compounds is calculated from the sum of the individual aromatic hydrocarbon types.
Compounds containing sulfur, nitrogen and oxygen can interfere in the determination; mono-alkenes do not interfere, but conjugated di-alkenes and poly-alkenes, if present, can do so. The measurement ranges that apply to this method are given in Table 2 and Table 3.
NOTE 1   For the purpose of this document, the terms "% (m/m)" and "% (V/V)" are used to represent the mass fraction, µ, and the volume fraction, φ, of a material respectively.
NOTE 2   By convention, the aromatic hydrocarbon types are defined on the basis of their elution characteristics from the specified liquid chromatography column relative to model aromatic compounds. Their quantification is performed using an external calibration with a single aromatic compound for each of them, which may or may not be representative of the aromatics present in the sample. Alternative techniques and test methods may classify and quantify individual aromatic hydrocarbon types differently.
NOTE 3   Backflush is part of laboratory-internal maintenance.

Petroleum products and related products - Determination of kinematic viscosity by calculation from the measured dynamic viscosity and density - Method by constant pressure viscometer (ISO 18335:2024)
SIST EN ISO 18335:2024

This document specifies a procedure for determining dynamic viscosity, η, and density, ρ, for the calculation of kinematic viscosity, ν, of middle distillate fuels, fatty acid methyl ester fuels (FAME) and mixtures thereof, up to 60 % with middle distillate fuels, and lubricating oils (e.g. base oils, formulated oils), and synthetics, using a constant pressure viscometer. The range of kinematic viscosities covered in this test method is from 0,5 mm2/s to 2 000 mm2/s, with precision at 40 °C from 1,0 mm2/s to 1 286 mm2/s, and precision at 100 °C from 3,0 mm2/s to 157 mm2/s.
The result obtained using the procedure described in this document depends on the rheological behaviour of the sample. This document is predominantly applicable to liquids whose shear stress and shear rate are proportional (Newtonian flow behaviour). However, if the viscosity changes significantly with the shear rate, comparison with other measuring methods is only permissible at similar shear rates.

Petroleum and related products - Precision of measurement methods and results - Part 5: Statistical assessment of agreement between two different measurement methods that claim to measure the same property (ISO 4259-5:2023, Corrected version 2024-03)
SIST EN ISO 4259-5:2024

This document specifies statistical methodology for assessing the expected agreement between two test methods that purport to measure the same property of a material, and for deciding if a simple linear bias correction can further improve the expected agreement.
This document is applicable for analytical methods which measure quantitative properties of petroleum or petroleum products resulting from a multi-sample-multi-lab study (MSMLS). These types of studies include but are not limited to interlaboratory studies (ILS) meeting the requirements of ISO 4259-1 or equivalent, and proficiency testing programmes (PTP) meeting the requirements of ISO 4259-3 or equivalent.
The methodology specified in this document establishes the limiting value for the difference between two results where each result is obtained by a different operator using different apparatus and two methods X and Y, respectively, on identical material. One of the methods (X or Y) has been appropriately bias-corrected to agree with the other in accordance with this practice. This limit is designated as the between-methods reproducibility. This value is expected to be exceeded with a probability of 5 % under the correct and normal operation of both test methods due to random variation.
NOTE      Further conditions for application of this methodology are given in 5.1 and 5.2.

Petroleum products - Transparent and opaque liquids - Determination of kinematic viscosity and calculation of dynamic viscosity (ISO 3104:2023)
kSIST FprEN ISO 3104:2023

This document specifies Procedure A, using manual glass viscometers, and Procedure B, using glass capillary viscometers in an automated assembly, for the determination of the kinematic viscosity, ν, of both transparent and opaque products. The scope includes liquid petroleum products, fatty acid methyl ester (FAME), paraffinic diesel, hydrotreated vegetable oil (HVO), gas to liquid (GTL) and biofuel diesel mixtures up to 50 % FAME. The kinematic viscosity is determined by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, η, is obtained by multiplying the measured kinematic viscosity by the density, ρ, of the liquid. The range of kinematic viscosities covered in this test method is from 0,2 mm2/s to 300 000 mm2/s over the temperature range –20 °C to +150 °C.
NOTE       The result obtained from this document is dependent upon the behaviour of the sample and is intended for application to liquids for which primarily the shear stress and shear rates are proportional (Newtonian flow behaviour). If, however, the viscosity varies significantly with the rate of shear, different results can be obtained from viscometers of different capillary diameters. The procedure and precision values for residual fuel oils, which under some conditions exhibit non-Newtonian behaviour, have been included.

Oil spill identification - Petroleum and petroleum related products - Part 2: Analytical method and interpretation of results based on GC-FID and GC-low resolution-MS analyses
SIST EN 15522-2:2023

This document specifies a method to identify and compare the compositional characteristics of oil samples. Specifically, it describes the detailed analytical and data processing methods for identifying the characteristics of spill samples and establishing their correlation to suspected source oils. Even when samples or data from suspected sources are not available for comparison, establishing the specific nature (e.g. refined petroleum, crude oil, waste oil, etc.) of the spilled oil still helps to constrain the possible source(s).
This methodology is restricted to petroleum related products containing a significant proportion of hydrocarbon-components with a boiling point above 150 °C. Examples are: crude oils, higher boiling condensates, diesel oils, residual bunker or heavy fuel oils, lubricants, and mixtures of bilge and sludge samples, as well as distillate fuels and blends. While the specific analytical methods are perhaps not appropriate for lower boiling oils (e.g. kerosene, jet fuel, or gasoline), the general concepts described in this methodology, i.e. statistical comparison of weathering-resistant diagnostic ratios, are applicable in spills involving these kinds of oils.
Paraffin based products (e.g. waxes, etc.) are outside the scope of this method because too many compounds are removed during the production process [37]. However, the method can be used to identify the type of product involved.
Although not directly intended for identifying oil recovered from groundwater, vegetation, wildlife/tissues, soil, or sediment matrices, they are not precluded. However, caution is needed as extractable compounds can be present in these matrices that alter and/or contribute additional compounds compared to the source sample. If unrecognized, the contribution from the matrix can lead to false “non-matches”. It is therefore advisable to analyse background sample(s) of the matrix that appear unoiled.
When analysing “non-oil” matrices additional sample preparation (e.g. clean-up) is often required prior to analysis and the extent to which the matrix affects the correlation achieved is to be considered. Whether the method is applicable for a specific matrix depends upon the oil concentration compared to the “matrix concentration”. In matrices containing high concentrations of oil, a positive match can still be concluded. In matrices containing lower concentrations of oil, a false “non-match” or an “inconclusive match” can result from matrix effects. Evaluation of possible matrix effects is beyond the scope of this document.

Determination of flash point - Method for flash no-flash and flash point by small scale closed cup tester (ISO 3679:2022, Corrected version 2023-05)
SIST EN ISO 3679:2023

This document describes three procedures (A, B and C) covering determinations of flash no-flash and flash point.
Rapid equilibrium procedures A and B are applicable to flash no-flash and flash point tests of paints, including water-borne paints, varnishes, binders for paints and varnishes, adhesives, solvents, petroleum products including aviation turbine, diesel and kerosene fuels, fatty acid methyl esters and related products over the temperature range –30 °C to 300 °C. The rapid equilibrium procedures are used to determine whether a product will or will not flash at a specified temperature (flash no-flash procedure A) or the flash point of a sample (procedure B). When used in conjunction with the flash detector (A.1.6), this document is also suitable to determine the flash point of fatty acid methyl esters (FAME). The validity of the precision is given in Table 2.
Non-equilibrium procedure C is applicable to petroleum products including aviation turbine, diesel and kerosine fuels, and related petroleum products, over the temperature range –20 °C to 300 °C. The non-equilibrium procedure is automated to determine the flash point. Precision has been determined over the range 40 °C to 135 °C.
For specifications and regulations, procedures A or B are routinely used (see 10.1.1).

Petroleum and related products - Precision of measurement methods and results - Part 4: Use of statistical control charts to validate 'in-statistical-control' status for the execution of a standard test method in a single laboratory (ISO 4259-4:2021, Corrected version 2023-10)
SIST EN ISO 4259-4:2022

This document specifies the process and methodology for the construction, operation, and maintenance of statistical control charts to assess if a laboratory's execution of a standard test method is in-statistical-control and how to establish and validate the 'in-statistical-control' status.
It specifies control charts that are most appropriate for ISO/TC 28 test methods where the dominant common cause variation is associated with the long term, multiple operator conditions. The control charts specified for determination of in-statistical-control are: individual (I), moving range of 2 (MR2), and either the exponentially weighted moving average (EWMA) or zone-based run rules [similar to Western Electric (WE) run rules[3]] as sensitivity enhancement strategy to support the I-chart.
The procedures in this document have been primarily designed for numerical results obtained from testing of control samples prepared from a homogenous source of petroleum and related products in a manner that preserves the homogeneity of properties of interest between control samples. If the test method permits, a certified reference material (CRM) sample is used as a control sample provided the sample composition is representative of the material being tested and is not a pure compound; if this is done then the laboratory best establishes its own mean for the CRM sample.
This document is applicable to properties of interest that are (known to be) stable over time, and for data sets with sufficient resolution to support validation of the assumption that the data distribution can be approximately represented by the normal (Gaussian) model. Mitigating strategies are suggested for situations where the assumption cannot be validated.
