8.4.8 Sensitivity coeffi-
cient to sample
gas temperature
The sensitivity coefficient to
sample gas temperature shall
not exceed 0.3 µmol/mol/K (i.e.
0.35 mg/m³/K).
For system 1, the sensitivity coeffi-
cient to sample gas temperature is
0.00 µmol/mol/K).
For system 2, the sensitivity coeffi-
cient to sample gas temperature is
0.00 µmol/mol/K).

8.4.9 Sensitivity coeffi-
cient to the sur-
rounding tempera-
ture
The sensitivity coefficient to the
surrounding temperature shall
not exceed 0.3 µmol/mol/K (i.e.
0.35 mg/m³/K).
The sensitivity coefficient to the sur-
rounding temperature does not ex-
ceed the performance criteria of max.
0.3 µmol/mol/K. For both systems, the
highest value bst is used for the pur-
pose of evaluating uncertainty. For
system 1 it is 0.040 µmol/mol/K and
for system 2 it is 0.046 µmol/mol/K.

8.4.10 Sensitivity coeffi-
cient to electrical
voltage
The sensitivity coefficient to
electrical voltage shall not ex-
ceed 0.30 µmol/mol/V (i.e. 0.35
mg/m³/V).
The sensitivity coefficient of electrical
voltage bv does not exceed the per-
formance criteria of max. 0.30
µmol/mol/V stipulated in Standard
DIN EN 14626 at any point. For both
systems, the highest value bv is used
for the purpose of evaluating uncer-
tainty. For system 1 it is
0.001
µmol/mol/V and for system 2 it
is 0.001 µmol/mol/V.
