7.5 Assessment
The maximum long term drift at zero D
l,z
is -0.23 µmol/mol for system 1and -0.47 µmol/mol
for system 2. The maximum long term drift at span point D
l,s
is 0.64 % for system 1 and
-0.9 % for system 2.
Does this comply with the performance criterion? yes
7.6 Detailed presentation of test results
The individual results of the determination of long term drift behaviour are provided in Table
29.
