BRITISH STANDARD BS EN 590:2004 Incorporating corrigendum no. 1 Automotive fuels — Diesel — Requirements and test methods The European Standard EN 590:2004 has the status of a British Standard ICS 75.160.20 ��������� � ���� ���������������������������������������������� ����� Copyright European Committee for Standardization Provided by IHS under license with CEN Not for ResaleNo reproduction or networking permitted without license from IHS - - ` , , ` ` ` , , , , ` ` ` ` - ` - ` , , ` , , ` , ` , , ` - - - BS EN 590:2004 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 27 August 2004 © BSI 2007 ISBN 978 0 580 59200 3 National foreword This British Standard is the UK implementation of EN 590:2004, incorporating corrigendum December 2005. It supersedes BS EN 590:2000, which is withdrawn. The start and finish of text introduced or altered by corrigendum is indicated in the text by tags ˜™. Text altered by CEN corrigendum December 2005 is indicated in the text by ˆ‰. The UK participation in its preparation was entrusted to Technical Committee PTI/2, Liquid fuels. A list of organizations represented on this committee can be obtained on request to its secretary. EN 590 requires that each country implementing it establishes national annexes detailing requirements for “pump marking”, and summer and winter grades. Also, if the methods for sampling given in EN ISO 3170 or EN ISO 3171 are not to be used, a national annex has to detail the national requirements for sampling automotive diesel fuel. National Annex NA of BS EN 590 gives additional requirements on sampling, in particular for sampling from the pump; National Annex NB gives details of requirements for pump marking; and National Annex NC gives details for summer and winter grades. The principal differences between BS EN 590:2000 and this edition are as follows: — the pump and nozzle marking requirements in National Annex NB recommends that the prominent colour be black rather than the previous choice of black, blue or yellow, and that a 2 year phase-in period would be allowed for fuel suppliers to change their dispensers; — the winter changeover dates in National Annex NC now run from 16 November to 15 March inclusive for sales from the retail pump; the dates for deliveries from refineries and import terminals are unchanged at 16 October to 15 March inclusive. The date for the change from summer grade to winter grade will be reviewed in the light of experience. This publication does not purport to include all the necessary provisions of a contract.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2004, and conflicting national standards shall be withdrawn at the latest by July 2004. This document supersedes EN 590:1999. Significant technical changes between this European Standard and the previous edition are: - The requirements of the European Fuels Directive 98/70/EC [1], including amendment 2003/17/EC [2] have been included, supporting early national introduction of maximum 10 mg/kg sulfur automotive diesel fuel. - Provision is made for a maximum of 5 % (V/V) of fatty acid methyl esters (FAME) to be included in automotive diesel fuel. - Dates have been included with all normative test method references in order to comply with the requirements of the European Commission, with the accompanying assurance that updated versions will always give similar accuracy and the same or better precision. - Table 1 explicitly differentiates between requirements included in the European Fuels Directive 98/70/EC [1], including Amendment 2003/17/EC [2], and other requirements. - Many of the test methods included in this standard were the subject of inter-laboratory testing to determine the applicability of the method and its precision in relation to blends of automotive diesel fuel containing 5 % (V/V) of different sources of fatty acid methyl esters (FAME). These fatty acid methyl esters were produced from rapeseed and sunflower oil. Annex A is normative and contains the precision data generated on the test methods which are the result of the inter-laboratory testing as mentioned above, carried out by working groups of CEN/TC19.This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Suitable fuel additives without known harmful side-effects are recommended in the appropriate amount, to help to avoid deterioration of driveability and emissions control durability. Other technical means with equivalent effect may also be used. NOTE Deposit forming tendency test methods suitable for routine control purposes have not yet been identified and developed. 5.3 Fatty acid methyl ester (FAME) Diesel fuel may contain up to 5 % (V/V) of FAME complying with EN 14214. NOTE A suitable method for the separation and identification of FAME is given in EN 14331 [3]. 5.4 Generally applicable requirements and related test methods 5.4.1 When tested by the methods indicated in Table 1, automotive diesel fuel shall be in accordance with the limits specified in Table 1. 5.4.2 The limiting value for the carbon residue given in Table 1 is based on product prior to addition of ignition improver, if used. If a value exceeding the limit is obtained on finished fuel in the market, EN ISO 13759 shall be used as an indicator of the presence of a nitrate-containing compound. If an ignition improver is thus proved present, the limit value for the carbon residue of the product under test cannot be applied. The use of additives does not exempt the manufacturer from meeting the requirement of maximum 0,30 % (m/m) of carbon residue prior to addition of additives.

FAME, if present in diesel fuels, will overestimate the value for polycyclic aromatic hydrocarbons.
