# SummaryNotesByYear

Notes:
A synthesis of information intended to the surveillance of quality of petrol collected during the year 2001 (from January to December) by grade of petrol, unleaded petrol with anti-recession added products valves (ARS) and unleaded petrol 95 (SP95) and 98 (SP98), is attached as three summary tables in Annex Ia to Ic.  Test methods are the one included in EN228:2000 standards.

We will note that the inspection revealed only one sample of unleaded petrol 98 with a very low sulphur content of 1mg/kg of sulphur in Ile de France (Yvelines) and four samples of petrol with 10 to 50 mg/kg of sulphur: 
-	one petrol ARS sample in Ile de France (Yvelines: with 50 mg/kg of sulphur),
-	one unleaded petrol 98 sample in Rhône-Alpes (Rhône with 50 mg/kg of sulphur) 
-	and 2 unleaded petrol 95 samples in Languedoc and in Ile de France (Aude with 40 mg/kg of sulphur and Yvelines with 50mg/kg).

Only one petrol fuel sample has its content in sulphur over the maximum specification admitted by the Directive i.e. 150 mg/kg (Regions: Languedoc and Aude) with 210 mg/kg of sulphur. In general, contents in sulphur for unleaded petrol 95, 98 and ARS are respectively situated in the ranges of:

-	SP95: 90 mg/kg to 120 mg/kg
-	SP98: 60 mg/kg to 110 mg/kg
-	ARS: 60 mg/kg to 120 mg/kg

The Benzene specification is always respected, except from one unleaded petrol SP98 sample in the Puy de Dôme with 4% of Benzene.

Specifications concerning the distillation are always respected, except for two cases. One is with unleaded petrol SP95 having a percentage distillation at 70ºC of 45.5%.  The second is with unleaded petrol SP98 having a distillation percentage of 70ºC of 45% for a specification of 46% minimum.  These two petrol values are however very close to the specification.

For samples in which an inspection have been made (inspection not systematically realised), specification concerning lead is respected and very close to zero, except for one unleaded petrol SP95 sample with 0.012 g/l of lead.

Analyses which have been inspected in 2001: voluminal mass, distillation (percentage at 170ºC, at 100ºC, at 150ºC and final point), content in sulphur, benzene and potassium (mainly ARS, NF M07-065 method).

A synthesis of information intended to the surveillance of quality of diesel fuels collected during the year 2001 (from January to December) is attached as summary tables in Annex II. Test methods are the one included in EN590:2000 standards.

Specifications in voluminal mass are respected except from diesel with paraffin which is below minimum administrative specification of 820 kg/m3 (voluminal mass of 816.9 kg/m3 for which the calculated cetane index is 61.2) and a diesel fuels sample with a voluminal mass which slightly goes over the maximum specification, with 845.9 kg/m3.

The specification in sulphur content is always respected, except from a sample which slightly goes over the limit value with 370 mg/kg.  One diesel fuels sample shows content in sulphur below 50mg/kg.

Most of samples have content in sulphur comprised between 270 and 330mg/kg.

Point 95% distilled has not been determined: only percentages distilled at 250ºC and 350ºC have been measured.

Indexes of cetane are only indexes calculated from the voluminal mass and distillation, and follows the method NF EN ISO 6245.  There was no measure of cetane on engine CFR.  All the indexes calculated comply with the minimum specification of 46.  Most of results are situated between 49 and 52.  Only one measure goes beyond 55 (61.2).

Analyses which have been inspected in 2001: voluminal mass, distillation (percentage at 250ºC, at 350ºC and in some cases at 360ºC), content in sulphur, flash point (NF EN 22719), content in Methyl Esther of Colza, viscosity at 40ºC (NF EN ISO 2104) and index of calculated cetane (NF EN ISO 6245).


Notes:
The monitoring data for Germany are collated in the appendices for petrol (I,1), Super Petrol (I/2) and SuperPlus (I/3).  National specifications like density and vapour pressure in winter are included.
Together the values show that the S-content on average for 2001 already corresponds to low-S goods.  The content of aromatic hydrocarbons also corresponds on average to the limit values that do not have to be reached until 2005.

Monitoring data on diesel are collated in appendices for diesel (II/1), low-S diesel (II/2), and S-free diesel (II/3).  The ignition point is added as a national specification. The testing of the petrol station goods shows that with tax incentives low-S fuels were sold from November everywhere with the same corresponding quality.

1.  O2 content in Super-Plus Petrol
The O2 content was not measured.  We don’t believe this to be critical, because it can be easily calculated from the MTBE content.  As the MTBE-measurement results are in line with the limits (i.e. below), likewise so must the O2 content be below the prescribed maximal limits.

2.  PAH-measurements in Sulphur-free diesel
As in chapter 5 of the report, S-free diesel was not sold at petrol stations in 2001 in Germany.  In accordance with German Law diesel was not subject to a test for PAHs for the FQM.  The testing federal authorities instigated the analyses because of the adherence to the S-limit value.

3. Standard deviation of the measurements
The reported values for fuel quality in Germany come from twelve federal reports in the form of approximately thirty datasets.  The standard deviation was not reported as a rule in these datasets.  The single data were weighted with their frequency against the mean value for the report’s production.  A standard deviation cannot be reported (however) due to a lack of data.


Notes:
Vapour pressure
The summer limit (60 kPa) has been exceeded in one (1) sample by 0.5 %.
Distillation 95%point
The limit value has been exceeded in one (1) sample by 1.1%.


Notes:
It should be noted that since 1 March 2002 when the Government introduced a higher excise duty rate (as permitted by Council Decision 2002/23/EC in accordance with Article 8(4) of Directive92/81/EEC) for diesel fuel with a maximum sulphur content greater than 50 ppm, the entire automotive diesel market has switched to the cleaner fuel at or below 50 ppm. This will be reflected in 2002 reporting requirements in due course.

Initially 31 individual  parameters from 26 samples (25 petrol and 1
diesel) were indicated as being outside the specifications of 98/70/EC. The
parameters were sulphur (7), RON (3), MON (1), olefins (1), vapour pressure
(2), aromatics (2), benzene (2), distillation: evaporation at 100 degrees
(12) and distillation  at 95% point (1). The last parameter relates to a
diesel sample, all the rest to petrol samples.

However, taking into account  the appropriate margin of tolerance (test
reproducibility) of the analysis methods into consideration  only 7
individual parameters from 6 different samples remained at issue . The
sample with 2 parameters at issue concerned aromatics content and
distillation (evaporation at 100 degrees).

Of these 7 parameters the breakdown is as follows:

2 parameters relate to benzene which are in compliance when the
reproducibility is considered to one decimal place as are the parameters in
the directive but outside the directive when the reproducibility is
considered to two decimal places as was done in Ireland following
procedures in the relevant standard (ISO 4259). This is a discrepancy in
the legislation and has been raised with CEN by Italy in the past we
understand. The matter should be addressed in a forthcoming revision to EN
228,  the general standard relating to gasoline quality. On this basis,
these samples cannot be considered to have exceeded the requirements of
98/70/EC.

4 parameter relate to distillation point. However, one sample was taken on
28/5/01 and analysed on 27/4/02. Given the long storage time some
evaporation may have occurred which could affect the distillation point and
as such the sample cannot categorically be deemed to be in breach of 98/70.
The other 3 parameters were stored in excess of 6 months and so also cannot
be deemed categorically to be in exceedence of 98/70/EC.

The final 1 parameter relates to aromatics which is outside the
specification though again the sample had been held for over 11 months.

Ireland is taking steps
administratively to ensure the time lag between sampling and analysis is
much shortened to avoid any future uncertainty in terms of evaporation etc.


Notes:
For petrol 95<RON<98 and RON>98 only import sales data was available for 2001.  Quantities produced nationally were unavailable.


Notes:
Luxemburg has been unable to supply measurements data for:
Petrol:- olefins, aromatics; all oxygenates; lead content.
Diesel:- PAH

The data of those parameters have not been supplied to us. Those importers who
had supplied data informed us that these data were not available to them at that
moment, so that they could not give us the information. As far as possible a complete data set will be prepared for this year's communication.


Notes:
In one case the aromatics measurements were too high (44.8%).


Notes:
1) Petrol (RON>98) (Summer):  one sample exceeded the DVPE Vapour Pressure limit values – 77,7 KPa.

2) Petrol (95<RON<98) (Summer):  one sample exceeded the DVPE Vapour Pressure limit values – 79,3KPa.

3) All petrol samples: sulphur content is significantly above the limit value of 100 mg/Kg, because Portugal had a derogation for the sulphur content in petrol until 31-12-2001, given by the European Commission.

As only ether's with five or more carbon atoms per molecule are added to petrol in Portugal, measurements of other oxygenates are not carried out.


Notes:
Number of samples exceeded the % oxygen content limit values (2,7 % m/m):
Petrol (RON 95) (Summer) - Three samples (3,0 , 3,0  and 3,1 % m/m respectively);
Petrol (RON 97) (Winter) - One sample (3,1 % m/m);
Petrol (RON 98) (Summer) - Three samples (3,0 % m/m all of them).


Notes:
In Sweden a total investigation was carried out were nearly all fuels, every freight to depot, was analysed.  Only the total number of freights/analyses are known and not the distribution over months.  The standard deviation has not been calculated since early wharf rates are analysed.


Notes:
In 2001 a tax incentive was given in the UK for low-sulphur petrol (50 ppm), this made it difficult for industry to give accurate production data.  An estimate of the portion of petrol sold that was low-sulphur is 35%.

All samples tested fully met the environmental requirements of the Directive and this included all transport fuels manufactured and imported into the UK. Retail surveys conducted by the industry have also confirmed that the fuels fully meet the limit value requirements of the Directive and show the fuels have not been contaminated in the supply chain to the consumer. No petrol or diesel marketed in the UK during 2001 contained less than 10ppm sulphur.

All diesel fuel marketed in the UK during 2001 exceeds the specification listed in Annex IV of the Directive, which is due to come into force in 2005. Although one sample exceeded the sulphur spec but was within the limits of Annex II. By the end of 2001 all petrol marketed in the UK fully met the requirements of Annex III which is due to come into force in 2005.
