7.1 8.5.7 Period of availability of the analyser
The availability of the analyser shall be at least 90 %.
7.2 Test procedure
The correct operation of the analysers shall be checked at least every 14 days. It is recom-
mended to perform this check every day during the first 14 days. These checks consist of
plausibility checks on the measured values, as well as, when available, on status signals and
other relevant parameters. Time, duration and nature of any malfunctioning shall be logged.
The total time period with useable measuring data is the period during the field test during
which valid measuring data of the ambient air concentrations are obtained. In this time peri-
od, the time needed for calibrations, conditioning of sample systems and filters and mainte-
nance shall not be included.
The availability of the analyser is calculated as:

a
A
is the availability of the analyser in (%);
u
t
is the total time period with validated measuring data;
t
t
is the time period of the field test minus the time for calibration, conditioning and
maintenance.
u

and

shall be expressed in the same units.
The availability shall meet the performance criterion as specified above.
7.3 Testing
Using the equation given above, availability was calculated on the basis of the overall time of
the field test and the down times which occurred during this period.
