8、 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. Supersession This British Standard supersedes BS 7800:2000, which is withdrawn. Information about this document In preparing this revision t
9、he 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 in this British Standard. The first edition of this British Standard w
10、as 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of high octane unleaded petrol1) and was also consistent with the provisions of EEC Directive 85/210/EEC 1 (since withdrawn) concerning the lead and benzene contents of petrol. The quality of leaded petrol is specified in BS 4040, and that of “p
11、remium” 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 Transport to enable oil companies who wished to market a grade of unlea
12、ded 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 unleaded petrol with a minimum research octane number (RON) of 98 and for u
13、niform 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 incorporates requirements for volatility levels appropriate to seasonal
14、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 unleaded petrol. On 1 October 1999 RON was reduced from 98 to 97
15、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 increased and a maximum density was introduced. 1) The term “petrol
16、” is used in this British Standard as being that most generally used by motorists in the UK: “gasoline” and “motor spirit” are alternatives.

17、 iv 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 2003/17/EC 3; c)t
18、he 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. In particular
19、 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 Gasoline Engine C

Hazard warnings WARNING. This British Standard calls for the use of substances and/or procedures that can be injuri
21、ous 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.
