12、drawn. Foreword This British Standard has been prepared under the direction of Technical Committee PTI/2, Liquid fuels. This revision supersedes BS 7800:1992 which is withdrawn. In preparing this revision the Technical Committee recognized that since the 1992 edition was prepared a grade of high oct
13、ane unleaded petrol containing valve seat recession protection additives has become commercially available. That grade is not included in this British Standard. The Technical Committee is preparing a separate British Standard specification for high octane unleaded petrol containing valve seat recess
14、ion protection additives. 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 of 20 March 1985 concerning the lead and benzene contents of petrol.
15、The quality of leaded petrol is specified in BS 4040, and of premium and regular grades of unleaded petrol in BS EN 228. The lead and benzene contents of these fuels are also covered by the same EEC Directive. The first edition of this standard was published at the request of the Department of Trans
16、port 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 is made for a high octane grade of unleaded petro
17、l 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 incorporate
18、s recommendations for volatility levels appropriate to seasonal temperature variations in the UK for petrol supplied to and sold from filling stations, in line with those recommended for petrol in BS EN 228. The fuels covered by this standard are intended for use in petrol-engined road vehicles whic
19、h require high octane unleaded petrol. The principal changes from the 1992 edition in this revision are as follows: (a) it incorporates requirements for volatility levels appropriate to seasonal temperature variations in the UK for petrol supplied to and sold from filling stations, in accordance wit
20、h those for petrol in BS EN 228; (b) the limit for sulfur is reduced from 0.2 % (m/m) to 0.05 % (m/m); (c) valve seat protection additives should not be included; (d) the method of determining vapour pressure has been changed from the Reid method given in BS 2000 : Part 692)to the air saturated meth
21、od given in BS 2000 : Part 394. NOTE When laboratory testing petrol for conformance with the requirements of clause 4 of this British Standard it is necessary to use equipment and procedures exactly as laid down in the appropriate test methods. In particular it is essential to use properly inspected
22、 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 Engine Test Correlation Programme of the Institute of Petr
23、oleum. Details of this programme are available from the Institute of Petroleum or the British Standards Institution. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a
24、British Standard does not of itself confer immunity from legal obligations.

37、s For the purposes of this British Standard all sampling shall be carried out in accordance with the relevant procedures of BS 3195:Part 1 and, additionally, as specified in 3.2. NOTE 1Attention is drawn to the special precautions required for samples for the determination of air saturated vapour pr
38、essure (see BS 2000:Part 394). NOTE 2The method described in 3.2 is designed for sampling the bulk of fuel being fed to the off-take point. The examination of equipment, e.g. pumps, to detect faulty operation, may require the use of different techniques. 3.2 Sampling from pipelines For the purposes
39、of this British Standard all sampling shall be carried out in accordance with the relevant procedures of either BS 3195:Part 1:1989 or BS 3195:Part 2:1989 and additionally as specified in 3.3 (see note 2 to 3.1). BS 3195:Part 2:1989 shall be used in combination with a variable volume receiver which
40、maintains the integrity of the sample.

41、cted from lead-free material except that lead solder may be used for the attachment of external fittings. They shall be provided with screw caps incorporating a petroleum resistant washer in good condition. NOTE 1The construction of the cans should conform to the appropriate safety requirements for
42、cans that are to hold highly flammable material. A stock of cans shall be kept solely for the purpose of taking samples of high octane unleaded petrol. Such cans shall be clearly identified and kept separate from cans used for the purpose of taking samples of leaded petrol in accordance with BS 4040
43、, or of premium or regular grades of unleaded petrol in accordance with BS EN 228. NOTE 2Attention is drawn to the fact that sampling cans should conform to statutory safety requirements for the classification, packaging and labelling of dangerous substances. 3.3.2 Preparation of cans New cans shall
44、 be rinsed with high octane unleaded petrol before being used, to remove any residual traces of oil left during manufacturing operations, and then allowed to dry. Before use, all cans shall be checked to ensure that they are sound and free from leaks. 3.3.3 Sampling procedure Draw 5 l of petrol , fr
45、om the clean pump nozzle, carefully into a cool 5 l can using a clean dry funnel. Immediately afterwards, decant this sample carefully into the requisite number of 1 l (see note 2) cans, using a funnel, filling the cans within 15 mm of the brim. If more than 5 l are needed, repeat the operation imme
46、diately before the pump has been used for any other purpose. Tighten the screw caps fully and check the cans to ensure that there are no leaks. The sampling procedure shall not be carried out in direct sunlight. NOTE 1If carried out in direct sunlight, changes in fuel quality, especially octane leve
47、l, may occur. NOTE 2A quantity of 1 l is sufficient for the determination of octane number and other tests but it is advisable to provide each laboratory with 2 l of sample in case further work is needed; it is essential that these 2 l are identical. 3.3.4 Storage, labelling and transport Samples sh
48、all be kept in a cool place although it is not necessary to keep them refrigerated. NOTE 1If left in direct sunlight there is a danger that the cans will balloon. Full and legible information relating to the source of the sample shall be attached to the can in such a manner that it will not easily b
49、ecome subsequently detached. NOTE 2If required, the sample may be sealed and labelled to maintain its legal integrity. NOTE 3If the sample has to be sent to a laboratory by public transport, it will be necessary to comply with the general regulations covering transportation of flammable materials and with the requirements of the transport authority concerned. Information on the appropriate procedures and the type of packaging required should be obtained from the transport authority involved.
