6.1 5.3.13 Short-term drift
The short-term drift at zero point and reference point shall not exceed the require-
ments of Table 2 of VDI 4202, Sheet 1 (September 2010) within 12 h (for benzene
24 h) in the laboratory test and within 24 h in the field test. A value c
t
at 70 % to
80 % of the upper limit of the certification range shall be used as reference point.
The short-term drift at zero point shall not exceed 0.1 µmol/mol (i.e. 0.12 mg/m³).
The short-term drift at span point shall not exceed 0.60 µmol/mol (i.e. 0.70 mg/m³).
6.2 Equipment
Not applicable here.
6.3 Testing
Performance and evaluation of the steps taken to determine the short-term drift are in line
with the requirements stipulated in DIN EN 14626 (2012). The reader is therefore referred to
section 7.1 8.4.4 Short-term drift.
6.4 Evaluation
Please see section 7.1 8.4.4 Short-term drift.
6.5 Assessment
Please see section 7.1 8.4.4 Short-term drift.
Does this comply with the performance criterion? yes
6.6 Detailed presentation of test results
