Field testing laboratory K05 Mechanical quantities

Brake tester - Electronic transducer

Range
Uncertainty (CMC)
Range
0,9 kN til 12,2 kN
Uncertainty (CMC)
± 0,020 kN ved 0,9 kN
Range
Uncertainty (CMC)
± 0,072 kN ved 12,2 kN

Remarks/ref. to internal procedure: The object is calibrated with an electronic transducer. This is used to gradually apply a given load that is compared with the value measured by the unit under test (the object).

Brake tester - Dead weight

Range
Uncertainty (CMC)
Range
0,9 kN til 8,2 kN
Uncertainty (CMC)
± 0,016 kN ved 0,9 kN
Range
Uncertainty (CMC)
± 0,055 kN ved 8,2 kN

Remarks/ref. to internal procedure: The object is calibrated with weights. These are used to gradually apply a given load which is compared with the value measured by the unit under test (the object).
Field testing laboratory K07 Fluid quantities

Exhaust gases analyser - Carbon monoxide

Range
Uncertainty (CMC)
Range
0,90 vol% til 5,50 vol%
Uncertainty (CMC)
± 0,04 vol% ved 0,90 vol%
Range
Uncertainty (CMC)
± 0,07 vol% ved 5,50 vol%

Remarks/ref. to internal procedure: The object is calibrated using a zero point and a minimum of two reference gases with different concentrations, one with low concentration and one with high concentration.

Exhaust gases analyser - Carbon dioxide

Range
Uncertainty (CMC)
Range
4,0 vol% til 15,0 vol%
Uncertainty (CMC)
± 0,2 vol%

Remarks/ref. to internal procedure: The object is calibrated using a zero point and a minimum of two reference gases with different concentrations, one with low concentration and one with high concentration.

Exhaust gases analyser - Hydrocarbons

Range
Uncertainty (CMC)
Range
700 vol-ppm til 4300 vol-ppm (propan)
Uncertainty (CMC)
± 18 vol-ppm ved 700 vol-ppm
Range
Uncertainty (CMC)
± 67 vol-ppm ved 4300 vol-ppm

Remarks/ref. to internal procedure: The object is calibrated using a zero point and two reference gases with different concentrations, one with low concentration and one with high concentration. For measurement, propane is used so that all gas concentrations in this document are stated in propane. The gas is converted from propane to hexane by conversion with instrument-dependent P.E.F factor when calibrating exhaust gas meters
Field testing laboratory K08 Optical quantities

Diesel smoke meter - K-value

Range
Uncertainty (CMC)
Range
0,60 m-1 til 5,90 m-1
Uncertainty (CMC)
± 0,04 m-1 ved 0,60 m-1
Range
Uncertainty (CMC)
± 0,10 m-1 ved 5,90 m-1

Remarks/ref. to internal procedure: The object is calibrated using a zero point and 2 or more reference filters (with low and high opacity).

Diesel smoke meter - Opacity

Range
Uncertainty (CMC)
Range
24 % til 95 %
Uncertainty (CMC)
± 0,6 %

Remarks/ref. to internal procedure: The object is calibrated using a zero point and 2 or more reference filters (with low and high opacity).

Headlamp beam tester

Range
Uncertainty (CMC)
Range
0 mm/m til 40,0 mm/m (nedvinkling)
Uncertainty (CMC)
± 1,4 mm/m
Range
Uncertainty (CMC)

Remarks/ref. to internal procedure: The object is calibrated using a calibrated laser that is placed perpendicular to the light box. The laser light is focused through the lens of the light box. The light box has a horizontal centerline. The correction between the laser light and the center line in the horizontal direction is determined.
