7.1 8.6 Total uncertainty in accordance with Annex E of DIN EN 14626
(2012)
The type approval of the analyser consists of the following steps:
1) The value of each individual performance characteristic tested in the laboratory
shall fulfil the criterion stated in Table E.1 of DIN EN 14626.
2) The expanded uncertainty calculated from the standard uncertainties due to the
values of the specific performance characteristics obtained in the laboratory tests
shall fulfil the criterion as stated in Annex I of Directive 2008/50/EC (15 % for fixed
measurements or 25 % for indicative measurements). This criterion is the maximum
uncertainty of hourly values of continuous measurements at the hourly limit value.
The relevant specific performance characteristics and the calculation procedure are
given in Annex E of DIN EN 14626.
3) The value of each of the individual performance characteristics tested in the field
shall fulfil the criterion stated in Table E.1 of DIN EN 14626.
4) The expanded uncertainty calculated from the standard uncertainties due to the
values of the specific performance characteristics obtained in the laboratory and
field tests shall fulfil the criterion as stated in Annex I of Directive 2008/50/EC (15 %
for fixed measurements or 25 % for indicative measurements). This criterion is the
maximum uncertainty of hourly values of continuous measurements at the hourly
limit value. The relevant specific performance characteristics and the calculation
procedure are given in Annex E of DIN EN 14626.
7.2 Equipment
Calculation of total uncertainty in accordance with Annex E of Standard DIN EN 14626
(2012).
7.3 Testing
At the end of the tests for type approval, total uncertainty was calculated using the values ob-
tained during testing.
7.4 Evaluation
1) The value of each individual performance characteristic tested in the laboratory fulfils
the criterion stated in Table E.1 of EN 4626.
2) The expanded uncertainty calculated from the standard uncertainties due to the values
of the specific performance characteristics obtained in the laboratory test fulfils the cri-
terion.
3) The value of each of the individual performance characteristics tested in the field fulfils
the criterion stated in Table E.1 of DIN EN 14626.
4) The expanded uncertainty calculated from the standard uncertainties due to the values
of the specific performance characteristics obtained in the laboratory and field tests ful-
fils the criterion.
7.5 Assessment
The total uncertainty of the measuring system complies with the performance criteria.
Does this comply with the performance criterion? yes
