Introduction
th
During its 8 meeting held in London on 25 - 26 October 2000, CEN/TC 19/WG 27 "Elemental analysis of
petroleum and related products" decided to carry out a second round robin, after the first performed in 1998 -
1999, to define the precision of new test methods in the range 1 mg/kg to 60 mg/kg sulfur. The range of sulfur
content was selected to obtain definite and robust precision statements for future sulfur limits. The round robin
was carried out in 2001.
The work has formed the basis for sulfur test method standards produced by the following organizations:
 ISO/TC 28 "Petroleum products", and
 CEN/TC 19 "Petroleum products, lubricants and related products".

1 Scope
This Technical Report summarises the activity carried out by CEN/TC 19 to define the precision of new test
methods for the determination of low sulfur content in automotive fuels. The full description of the activity can
be found in the Working Group Report completed in August 2002, which is an internal CEN/TC 19 document.
2 Test methods
WG 27 identified the most suitable instrumental methods to include in the round robin, also according to the
experience gained in the round robin carried out in 1999. The methods available at that time and used in the
assessment are listed below (see also Clause 12).
- EN ISO 14596 WDXRF (with internal standard) [1];
- ISO/CD 20846 UVF [2];
- ISO/CD 20847 EDXRF [3];
- ISO/CD 20884 WDXRF (without internal standard) [4];
- prEN ISO/DIS 16591 Oxidative microcoulometry [5].
3 Samples
Eight petrol and ten diesel samples with sulfur content from 1 mg/kg to 55 mg/kg were included in the round
robin. Two samples were blends of FAME in diesel (5 % (V/V) FAME) and were included in the round robin to
examine the applicability of the methods to FAME blends according to EN 590 specification [6].
Two samples (one petrol and one diesel) were considered as “quality control” samples, to check for accuracy
of results, as sulfur content had been determined using Isotope Dilution Mass Spectrometry (ID-MS), the
technique employed for the certification of element content in reference materials.
4 Laboratories
European laboratories were contacted to obtain a satisfactory participation for the methods listed above. A
total of 102 applications from 11 countries were received. Table 1 shows the distribution of the techniques
employed by the laboratories that effectively participated in the round robin.
