This international standard describes methods for reducing combined samples (or increments) to laboratory

samples and laboratory samples to sub-samples and general analysis samples and is applicable to solid

biofuels.

The methods described in this international standard may be used for sample preparation, for example, when

the samples are to be tested for calorific value, moisture content, ash content, bulk density, durability,

particle size distribution, ash melting behaviour, chemical composition, and impurities.

This document applies to metering pumps, dispensers and remote pumping units to be installed at liquid fuel filling stations, designed to dispense flammable liquid fuels into the tanks of motor vehicles, boats and light aircraft and into portable containers at flow rates up to 200 l · min-1, and intended for use and storage at ambient temperatures between −20 °C and +40 °C. Measures in addition to those required by this European Standard might be required for use and storage at temperature outside this range. The need for and nature of additional requirements should be determined by the manufacturer, if necessary after consulting the client.

This document deals with all significant hazards, hazardous situations and events relevant to metering pumps, dispensers and remote pumping units, when they are used as intended and under the conditions foreseeable by the manufacturer (see Clause 4).

This document gives health and safety related requirements for the selection, construction and performance of the equipment.

This document does not deal with noise and with hazards related to transportation and installation.

This document does not include any requirements for metering performance.

Vapour recovery efficiency rates are not considered within this European Standard.

Fuels other than the ones of Explosion Group IIA are excluded from this European Standard.

This document is not applicable to metering pumps, dispensers and remote pumping units which are manufactured before the date of publication of this document by CEN.

This document does not apply to equipment for use with liquefied or compressed gases.

This document specifies safety requirements for the construction and performance of safe breaks to be fitted to metering pumps and dispensers installed at filling stations and used to dispense liquid fuels and aqueous urea solution into the tanks of motor vehicles, boats and light aircraft and into portable containers at flow rates up to 200 l · min-1.

This document applies to fuels of Explosion Group IIA and also aqueous urea solution according to ISO 22241-1.

NOTE Fuels other than of Explosion Group IIA are excluded from this European Standard.

The requirements apply to safe breaks at ambient temperatures from –20 °C to +40 °C with the possibility for an extended temperature range.

This document pays particular attention to electrical, mechanical and hydraulic characteristics of, and electrical apparatus incorporated within or mounted on, the safe break.

This document applies mainly to hazards related to the ignition of liquid fuels being dispensed or their vapour. This document also addresses electrical and mechanical hazards.

This document does not apply to equipment dispensing compressed or liquefied gases.

This document specifies a laboratory method for the determination of the distillation characteristics of light and middle distillates derived from petroleum and related products of synthetic or biological origin with initial boiling points above 20 °C and end-points below approximately 400 °C, at atmospheric pressure utilizing an automatic micro distillation apparatus.

This test method is applicable to such products as; light and middle distillates, automotive spark-ignition engine fuels, automotive spark-ignition engine fuels containing up to 20 % ethanol, aviation gasolines, aviation turbine fuels, (paraffinic) diesel fuels, FAME (B100), diesel blends up to 30 % fatty acid methyl esters (FAME), special petroleum spirits, naphtha’s, white spirits, kerosene’s, burner fuels, and marine fuels.

The test method is also applicable to hydrocarbons with a narrow boiling range, like organic solvents or oxygenated compounds.

The test method is designed for the analysis of distillate products; it is not applicable to products containing appreciable quantities of residual material.

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.
