8. Expert input required
Annex 5, Test equipment and calibrations Analyser calibration procedures
EXPERT PROPOSAL:
From I. Riemersma: It is not clear what is intended with this paragraph. Clearly it is not a requirement, but if that was the intention, it has to be rephrased into a requirement.
From drafting co.: it is taken straight from ECE-R 83.
From Les Hill: "range" should replace "scale". A value for "sensitivity" has never been specified previously. Having looked at the draft text, I cannot see any reason or any explanation for apart from the analyser component, range and date of linearisation. Sensitivity has never been a reported parameter.
From the trace of the linearization curve and the linearization points it is possible to verify that the calibration has been carried out correctly. The different characteristic parameters of the analyser shall be indicated, particularly:
(a) Scale;
(b) Sensitivity;
(c) Zero point;
(d) Date of the linearization.
