Workplace exposure - General requirements for the performance of procedures for the measurement of chemical agents
This European Standard specifies general requirements for the performance of procedures for the determination of the concentration of chemical agents in workplace atmospheres as required by the Chemical Agents Directive 98/24/EC (see reference [9]). The requirements given apply to all measuring procedures, irrespective of the physical form of the chemical agent (gas, vapour, airborne particles), the sampling method and the analytical method used.
This European Standard is applicable to
- all steps of a measuring procedure,
- measuring procedures with separate sampling and analysis steps, and
- direct-reading devices.
Exposition am Arbeitsplatz - Allgemeine Anforderungen an die Leistungsfähigkeit von Verfahren zur Messung chemischer Arbeitsstoffe
Diese Europäische Norm legt allgemeine Anforderungen an die Leistungsfähigkeit von Messverfahren zur Bestimmung der Konzentration chemischer Arbeitsstoffe in der Arbeitsplatzatmosphäre fest, wie seitens der Richtlinie über chemische Arbeitsstoffe 98/24/EG (siehe Literaturhinweis [7]) gefordert. Diese Anforderungen gelten für alle Messverfahren, unabhängig vom physikalischen Zustand des chemischen Arbeitsstoffes (Gas, Dampf, luftgetragene Partikel), vom Probenahmeverfahren und vom eingesetzten Analyseverfahren. Diese Europäische Norm gilt für
- alle Schritte eines Messverfahrens,
- Messverfahren mit voneinander unabhängigen Probenahme- und Analyseschritten, und
- direkt anzeigende Messgeräte.
Exposition sur les lieux de travail - Exigences générales concernant les performances des procédures de mesure des agents chimiques
La présente Norme européenne stipule les exigences générales de performances pour les procédures
servant à déterminer la concentration des agents chimiques dans les atmosphères des lieux de travail comme
demandé dans la Directive relative aux agents chimiques 98/24/CE (voir référence [7]). Ces exigences sont
applicables à toutes les procédures de mesure, indépendamment de la forme physique de l’agent chimique
(gaz, vapeur, particules en suspension dans l'air), de la méthode de prélèvement ou d’analyse employée.
La présente Norme européenne est applicable :
- à toutes les étapes d’une procédure de mesure ;
- aux procédures de mesure pour lesquelles le prélèvement et l’analyse sont deux étapes distinctes ; et
- aux dispositifs à lecture directe.

¶ 15 min), c) measuring range that is fit for purpose (see 4.3), and d) expanded uncertainty that is fit for purpose (see 4.3). 5.4 Measurements for comparison with limit values and periodic measurements 5.4.1 Unambiguity A measuring procedure shall produce an unambiguous result for the concentration of the chemical agent being measured in the specified measuring range, i.e. an analytically determined value shall correspond to one concentration only. 5.4.2 Selectivity The measuring procedure shall contain appropriate information about the nature and magnitude of any interference. NOTE Selectivity requirements vary from case to case, depending on what is known in advance about the workplace air. If the identity of all contaminants present is not known in advance then the measuring procedure will need to have a high selectivity. If the identity of all contaminants is known prior to measurement and there are no interferents present, then it might be possible to use a measurement procedure with a low selectivity. Procedures for measuring chemical agents present as airborne particles shall prescribe a method for sampling the particle size fraction, as defined in EN 481, for which the limit value for the chemical agent is set. If different limit values are set for different species of a chemical agent, then the measuring procedure shall determine the individual species concerned. 5.4.3 Averaging time The averaging time is equal to the sampling time, which shall be less than or equal to the limit value reference period.

¶ 50 % NOTE Variation of exposure to chemical agents in the workplace can be significantly greater than indicated by the uncertainty of a single measurement calculated according to this European Standard. This is due to the temporal and spatial variability of workplace exposure. ! 5.4.6 Chemical agents with low limit values In exceptional cases, the limit value of a chemical agent can be so low that at present no measuring procedure is available which meets the requirements given in 5.4.4 and 5.4.5. Until a measuring procedure which fulfils these requirements is available, a measuring procedure should be used whose performance is closest to the specified requirements. NOTE
A list of published measuring procedures is available from GESTIS Analytical methods database [11] which is updated regularly. These measuring procedures are rated according to their compliance with this European Standard and EN 838, EN 1076, EN 13890 and EN 13936." 5.5 Composite procedures The performance requirements detailed in 5.2, 5.3 and 5.4 shall be fulfilled for the whole measuring procedure even if the measuring procedure consists of several distinct steps, e.g. sampling, transport and storage, sample preparation and analysis. In the latter case, each step of the measuring procedure may be tested individually as an alternative to testing the measuring procedure as a whole. 5.6 Transport and storage Transport and storage of samples, if appropriate, shall be carried out in such a way that the physical and chemical integrity is maintained between sampling and analysis.
