This document specifies a wavelength-dispersive X-ray fluorescence (WDXRF) test method for the determination of the sulfur content of liquid, homogeneous automotive fuels from 5 mg/kg to 500 mg/kg, which have a maximum oxygen content of 3,7 % (m/m). This product range covers diesel fuels containing up to about 30 % (V/V) fatty acid methyl esters (FAME) and motor gasolines containing up to about 10 % (V/V) ethanol, and synthetic fuels such as Hydrotreated Vegetable Oil (HVO) and Gas To Liquid (GTL) having sulfur contents in the range of 5 mg/kg to 45 mg/kg.

NOTE 1 Sulfur contents higher than 500 mg/kg can be determined after sample dilution. However, the precision was not established for diluted samples.

Products with higher oxygen content show significant matrix effects, e.g. FAME used as biodiesel. Nevertheless, FAME may be analysed when the corresponding procedures are followed (see 5.3 and 8.1).

Other products may be analysed with this test method. However, precision data for products other than those mentioned have not been established for this document.

NOTE 2 For the purposes 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.

This document specifies an ultraviolet (UV) fluorescence test method for the determination of the sulfur content of motor gasolines containing up to 3,7 % (m/m) oxygen [including those blended with ethanol up to about 10 % (V/V)], diesel fuels, including those containing up to about 30 % (V/V) fatty acid methylester (FAME), having sulfur contents in the range 3 mg/kg to 500 mg/kg and synthetic fuels, such as Hydrotreated Vegetable Oil (HVO) and Gas To Liquid (GTL), having sulfur contents in the range of 3 mg/kg to 45 mg/kg.

Other products can be analysed and other sulfur contents can be determined according to this test method, however, no precision data for products other than automotive fuels and for results outside the specified range have been established for this document. Halogens interfere with this detection technique at concentrations above approximately 3 500 mg/kg.

NOTE 1 Some process catalysts used in petroleum and chemical refining can be poisoned when trace amounts of sulfur-bearing materials are contained in the feedstocks.

NOTE 2 This test method can be used to determine sulfur in process feeds and can also be used to control sulfur in effluents.

NOTE 3 For the purposes 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 4 Sulfate species in ethanol do not have the same conversion factor of organic sulfur in ethanol. Nevertheless, sulfates have a conversion factor close to that of organic sulfur.

NOTE 5 It is preferable to check the nitrogen interference and to take it into account, especially when sulfur content is measured on diesel blended with cetane improver containing nitrogen. For example, alkyl nitrate, as 2-ethyl hexyl nitrate (EHN), added as cetane improver to diesel fuel shows an enhancing effect on sulfur content that can range from (0 to 1,7) mg/kg when 2 000 mg/kg EHN is added to diesel fuel containing 10 mg/kg sulfur.

This International Standard specifies the methodology for the regular monitoring of the test method precision achieved versus precision published in the standard test method using data from Proficiency Testing (PT) schemes supported by the regular users of standard test methods.

The procedures in this International Standard are designed specifically for PTs' conducted on standard test methods for petroleum and petroleum related products, which are presumed to be homogeneous and where the data distribution is approximately normal.

The procedures in this document are designed specifically for standard test methods with published reproducibility derived from ISO 4259-1 or equivalent (such as ASTM D6300[1]) for petroleum and petroleum related products, which are normally considered as homogeneous.

In particular, this document specifies the methodology for the statistical comparison of standard deviation under reproducibility conditions achieved in PT programmes versus that published.

Purpose of this comparison is to ascertain if the published reproducibility precision is representative of that achievable by the regular participants in the PT programmes.

Guidance on how to use PT zz score to monitor an individual participant's performance over time is provided as an Informative Annex.

This document describes the metrological and technical requirements for flowmeters intended to be used in

the dynamic measurement of Liquefied Natural Gas (LNG) and other refrigerated hydrocarbon fluids.

This document sets the best practice for the proper selection and installation of flowmeters in cryogenic

applications and identifies the specific issues that can affect the performance of the flowmeter in use.

Moreover, it offers a calibration guideline for laboratory and on-site conditions (mass or volume) by either

using LNG or other reference fluids. The choice of calibration fluid will depend on the capabilities of available

flow calibration facilities and the ability to achieve the overall uncertainty demanded by the intended

application.

It is applicable, but is not limited to, the usage of Coriolis and ultrasonic flowmeters for dynamic measurements

of LNG.

In principle, LNG and other refrigerated liquid hydrocarbons are considered in the standard. Recommendations

in this standard are based on available test results with LNG. These results are probably applicable to other

cryogenic fluids.
