6.1 5.3.4 Linearity (lack of fit)
The analytical function describing the relationship between the output signal and the
value of the air quality characteristic shall be linear.
Reliable linearity is given, if deviations of the group averages of measured values
about the calibration function meet the requirements of Table 2 of VDI 4202, Sheet 1
(September 2010) in the certification range according to Table 1 of VDI 4202,
Sheet 1 (September 2010).
For all other certification ranges the group averages of measured values about the
calibration function shall not exceed 5 % of the upper limit of the corresponding cer-
tification range.
The deviation from the linear regression shall not exceed 4 %.
6.2 Equipment
Not applicable here.
6.3 Testing
Performance and evaluation of the steps taken to determine the lack of fit are in line with the
requirements stipulated in DIN EN 14626 (2012). The reader is therefore referred to section
7.1 8.4.6 Lack of fit of linearity of the calibration function.
6.4 Evaluation
Please refer to section 7.1 8.4.6 Lack of fit of linearity of the calibration function.
6.5 Assessment
Please refer to section 7.1 8.4.6 Lack of fit of linearity of the calibration function.
Does this comply with the performance criterion? yes
6.6 Detailed presentation of test results
Not applicable in this instance.
