12、enerally used by motorists in the UK: gasoline and motor spirit are alternatives. Foreword This British Standard has been prepared under the direction of Technical Committee PTI/2 liquid fuels. This revision supersedes BS 7800:1998 which is withdrawn. In preparing this revision, the Technical Commit
13、tee 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 was prepared to prov
14、ide a specification for the quality of high octane unleaded petrol1)and was also consistent with the provisions of EEC Directive 85/210/EEC (since withdrawn) concerning the lead and benzene contents of petrol. The quality of leaded petrol is specified in BS 4040, and that of premium and regular grad
15、es 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 unleaded petrol with a higher o
16、ctane 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 uniform marking. This standard
17、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 temperature variations in the
18、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. The second edition reduced the sulfur limit to 0.05 % (m/m) and changed the me
19、thod for determining vapour pressure to the air saturated method. The principal changes from the 1998 edition in this revision are as follows: a) the oxygenate requirements have been revised to conform to EU Directive 98/70/EC; b) hydrocarbon content requirements have been introduced to conform to E
20、U Directive 98/70/EC; c) the maximum benzene content has been reduced from 5 % (V/V) to 1 % (V/V) to conform to EU Directive 98/70/EC; d) the oxidation stability has been increased from 240 minutes to 360 minutes when tested by BS EN ISO 7536; e) the maximum sulfur content has been reduced to 150 mg
21、/kg; f) a maximum density has been introduced; g) a reduction in RON from 98 to 97 and MON from 87 to 86. NOTEWhen 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 appropr
22、iate test methods. 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 includi
23、ng it in the Engine Test Correlation Programme of the Institute of Petroleum. Details of this programme are available from the Institute of Petroleum or the British Standards Institution.

(BS 2000-156:1997) 3 Sampling 3.1 Sampling from storage tanks For the purposes of this British Standard, all sampling shall be carried out in accordance with the relevant procedures of BS EN ISO 3170 and, additionally, as specified in 3.2. NOTE 1Attention is dra
39、wn to the special precautions required for samples for the determination of air saturated vapour pressure (see BS 2000-394). 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 operati
40、on, may require the use of different techniques. 3.2 Sampling from pipelines For the purposes of this British Standard, all sampling shall be carried out in accordance with the relevant procedures of either BS EN ISO 3170:1999 or BS EN ISO 3171:1999 and additionally as specified in 3.3 (see note 2 t
41、o 3.1). The procedures of BS EN ISO 3171:1999 shall be used in combination with a variable volume receiver which maintains the integrity of the sample. 3.3 Sampling from petrol pumps 3.3.1 Sampling cans of 5 l and 1 l capacity Cans shall be constructed from lead-free material except that lead solder
42、 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 cans that are to hold highly flammable material. A s
43、tock 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, or of premium or regular grades of unleaded petrol
44、 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 be rinsed with high octane unleaded petrol before b
45、eing 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 Carefully draw 5 l of petrol from the clean pump nozzle into a cool 5 l can
46、 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 to within 15 mm of the brim. If more than 5 l are needed, repeat the operation immediately before the pump has been used for any other
47、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 level, may occur. NOTE 2A quantity of 1 l is sufficient
48、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.

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 become subsequently detached. NOTE 2If required, the sample may be sealed and labelle
