IEC 61207-1:2010
Expression of performance of gas analyzers - Part 1: General
Product Details
- all references (normative and informative) have been updated, deleted or added, as appropriate;
- all the terms and definitions relating to this International Standard have been updated;
- all references to errors have been replaced by uncertainties and appropriate updated definitions applied.
Where only one value is quoted for a performance specification, such as intrinsic uncertainty, linearity uncertainty or repeatability throughout a measurement range, this has now been defined as the maximum value, rather than an average or representative value. This was previously undefined. Where zero and 100 % span calibration gases are used, there is now a defined requirement that the analyser must be able to respond within its standard performance specifications beyond its normal measurement range, to allow for any under or over response of the instrument to be recorded. A new Annex A has been added giving recommended standard values of influence.
