7、ritish Standard was published by BSI and came into effect on 28 March 2006. It was prepared by Technical Committee PTI/2, Liquid fuels. A list of organizations represented on this committee can be obtained on request to its secretary.SupersessionThis British Standard supersedes BS 7800:2000, which i
8、s withdrawn.Information about this documentIn preparing this revision the Technical Committee recognized that since the 1992 edition was prepared, a grade of high octane unleaded petrol containing valve seat recession protection additives has become commercially available. That grade is not included
9、 in this British Standard.The first edition of this British Standard was prepared to provide a specification for the quality of high octane unleaded petrol1)and was also consistent with the provisions of EEC Directive 85/210/EEC 1 (since withdrawn) concerning the lead and benzene contents of petrol.
10、 The quality of leaded petrol is specified in BS 4040, and that of “premium” and “regular” grades of unleaded petrol in BS EN 228. The same EEC Directive also covered the lead and benzene contents of these fuels.The first edition of this standard was published at the request of the Department of Tra
11、nsport to enable oil companies who wished to market a grade of unleaded petrol with a higher octane rating than that defined as “premium” in BS EN 228 to identify such fuels as separate from the “premium” unleaded grade. In this British Standard, provision was made for a high octane grade of unleade
12、d petrol with a minimum research octane number (RON) of 98 and for uniform marking.This standard specifies maximum lead and benzene contents, minimum values for research octane number (RON) and motor octane number (MON), and defines limiting requirements for other essential properties. It also incor
13、porates requirements for volatility levels appropriate to seasonal temperature variations in the UK for petrol supplied to and sold from filling stations, in line with those in BS EN 228.The fuels covered by this standard are intended for use in petrol-engined road vehicles which require high octane
14、 unleaded petrol.On 1 October 1999 RON was reduced from 98 to 97 and MON from 87 to 86 by an announcement in Update Standards.The third edition ensured that the maximum content of oxygenates, olefins, aromatics, benzene and sulfur conformed to EU Directive 98/70/EC 2. The oxidation stability was inc
15、reased and a maximum density was introduced. 1)The term “petrol” is used in this British Standard as being that most generally used by motorists in the UK: “gasoline” and “motor spirit” are alternatives.

16、BSIBS 7800:2006iv The principal changes from the 2000 edition in this revision are as follows:a) the maximum sulfur content has been reduced to 50 mg/kg to conform to EU Directive 2003/17/EC 3;b) the maximum aromatic content has been reduced from 42% (V/V) to 35% (V/V) to conform to EU Directive 200
17、3/17/EC 3;c) the test methods have been updated to make them compatible with BS EN 228.NOTE When laboratory testing petrol for conformance with the requirements of Clause 5 of this British Standard it is necessary to use equipment and procedures exactly as laid down in the appropriate test methods.
18、In particular it is essential to use properly inspected and maintained standard Co-operative Fuel Research Committee (CFR) engines for the determination of both RON and MON. A useful guide to the satisfactory operation and test precision of a CFR engine can be obtained by including it in the IP Gaso
19、line Engine Correlation Scheme of the Energy Institute (formerly the Institute of Petroleum). Details of this programme are available from the Energy Institute or the British Standards Institution.Hazard warningsWARNING. This British Standard calls for the use of substances and/or procedures that ca
20、n be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage.CAUTION. In view of the sensitivity of some of the test methods referred to in this British Standard
21、, it is essential that attention is paid to the guidance on sampling containers included in the test method standard referred to.Use of this documentIt has been assumed in the preparation of this British Standard that the execution of its provisions will be entrusted to appropriately qualified and e
22、xperienced people, for whose use it has been produced.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general informative mat
23、erial is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British Standard can
24、not confer immunity from legal obligations.

25、unleaded petrol. It is aimed at the petroleum fuels industry, including retailers, manufacturers and suppliers. It is primarily intended to ensure compliance at the retail pump.2 Normative referencesNOTE Copies of the BS 2000 series of standards are available from the Energy Institute (formerly the
