Stationary source emission - Intralaboratory validation procedure for an alternative method compared to a reference method

The purpose of this technical specification is to specify a validation procedure to show if an Alternative Method (AM) can be used as an alternative to the Standard Reference Method (SRM), both implemented to determine the same measurand. This document has been drawn up for laboratories working in air pollution measurements (and consequently examples taken from this sector are included in the appendices).
In particular, this Technical Specification provides the statistical tools and different criteria to evaluate the alternative method; this does not release the person responsible for this validation from bearing technical and analytical judgement on the evaluation of the different criteria.
Three steps are described in the validation procedure:
-   description of the AM and setting of the field of equivalence (range and type of gas matrix);
-   determination of the performance characteristics of the AM and calculation of the overall uncertainty where appropriate and check of compliance of the maximum overall uncertainty allowed for the SRM;
-   check of repeatability and lack of systematic deviation of the AM in the field in comparison with the SRM for the type of matrix defined in the field of equivalence.
NOTE   Some parts of the second step of the validation of the alternative method should be performed by a recognised test-house.
If the AM fulfils the requirement of the procedure, then the laboratory that carried out the whole validation process is allowed to use it as a SRM in the field application where the equivalence has been demonstrated.
However, if the validation process involves at least 4 different accredited laboratories performing simultaneously parallel measurements in the field, and if the AM passes with success all the tests of the procedure, then this method could be proposed to CEN, who can decide to consider this AM as a new reference method (ARM).
The use of this procedure implies that a reference method has been defined by the regulator or i

Emissionen aus stationären Quellen - Laborinterne Validierung von Alternativverfahren durch Vergleich mit einem Referenzverfahren

Der Zweck dieser Technischen Spezifikation ist die Festlegung eines Validierverfahrens zum Nachweis, ob ein Alternativverfahren (AM) an Stelle des Standardreferenzverfahrens (SRM) angewendet werden kann, die beide zur Bestimmung derselben Messgröße eingesetzt werden. Dieses Dokument richtet sich an Laboratorien, die mit der Messung von Luftverunreinigungen befasst sind (daher werden Beispiele aus diesem Bereich in den Anhängen dargestellt)
Diese Technische Spezifikation enthält insbesondere statistische Methoden und verschiedene Kriterien zur Bewertung des Alternativverfahrens. Das entbindet aber nicht die für diese Validierung verantwortliche Person von der Aufgabe, die Auswertung der verschiedenen Kriterien technisch und analytisch zu beurteilen.

This Technical Specification (CEN/TS) was approved by CEN on 1 March 2004 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,
Slovenia, Spain, Sweden, Switzerland and United Kingdom.
