Workplace air - Metals and metalloids in airborne particles - Requirements for evaluation of measuring procedures (ISO 21832:2018)

This document specifies performance requirements and test methods for the evaluation of procedures for measuring metals and metalloids in airborne particles sampled onto a suitable collection substrate.
This document specifies a method for estimating the uncertainties associated with random and systematic errors and combining them to calculate the expanded uncertainty of the measuring procedure as a whole, as prescribed in ISO 20581.
This document is applicable to measuring procedures in which sampling and analysis is carried out in separate stages, but it does not specify performance requirements for collection, transport and storage of samples, since these are addressed in EN 13205-1 and ISO 15767.
This document does not apply to procedures for measuring metals or metalloids present as inorganic gases or vapours (e.g. mercury, arsenic) or to procedures for measuring metals and metalloids in compounds that could be present as a particle/vapour mixture (e.g. arsenic trioxide).

Luft am Arbeitsplatz - Metalle und Metalloide in luftgetragenen Partikeln - Anforderungen an die Evaluierung von Messverfahren (ISO 21832:2018)

Dieses Dokument legt Anforderungen an die Leistungsfähigkeit sowie Prüfverfahren zur Evaluierung von Messverfahren zur quantitativen Bestimmung von Metallen und Metalloiden in luftgetragenen Partikeln fest, die auf einem geeigneten Substrat, z. B. einem Filter, gesammelt wurden.
Dieses Dokument legt, wie nach ISO 20581 vorgeschrieben, ein Verfahren fest, mit dem Unsicherheiten, die mit zufälligen und systematischen Fehlern zusammenhängen, abgeschätzt werden können. Außerdem wird deren Kombination zum Berechnen der erweiterten Unsicherheit des Messverfahrens als Ganzes vorgeschrieben.
Dieses Dokument ist anzuwenden für Messverfahren, bei denen Probenahme und Analyse in getrennten Schritten durchgeführt werden. Es werden jedoch keine Leistungsanforderungen für die Sammlung, den Transport und die Lagerung von Proben festgelegt, da diese Aspekte in EN 13205 1 und ISO 15767 behandelt werden.
Dieses Dokument ist nicht anzuwenden für Verfahren zur quantitativen Bestimmung von Metallen und Metalloiden, die in anorganischen Gasen oder Dämpfen vorhanden sind, wie z. B. von Quecksilber, Arsen, oder für Verfahren zur quantitativen Bestimmung von Metallen und Metalloiden in Verbindungen, die als Partikel-Dampf-Gemisch vorliegen könnten (z. B. Arsentrioxid).

Air des lieux de travail - Métaux et métalloïdes dans les particules en suspension dans l'air - Exigences relatives à l'évaluation des procédures de mesure (ISO 21832:2018)

Le présent document précise les exigences de performance et les méthodes d'essai pour l'évaluation des procédures de mesure des métaux et métalloïdes présents dans les particules en suspension dans l'air échantillonnées sur un substrat de collecte approprié.
Le présent document spécifie une méthode permettant d'estimer les incertitudes associées aux erreurs aléatoires et systématiques et de les combiner pour calculer l'incertitude élargie de la procédure de mesure dans son ensemble, comme spécifié dans l'ISO 20581.
Le présent document s'applique aux procédures de mesure qui dissocient l'étape de prélèvement de l'étape d'analyse, mais il ne précise aucune exigence de performance concernant la collecte, le transport et le stockage des échantillons, dans la mesure où ces exigences sont traitées dans l'EN 13205‑1 et l'ISO 15767.
Le présent document ne s'applique pas aux procédures de mesure des métaux ou métalloïdes présents dans des gaz ou des vapeurs inorganiques (par exemple le mercure, l'arsenic), ni aux procédures de mesure des métaux et métalloïdes présents dans des composés pouvant exister sous forme de mélange de particules/vapeurs (par exemple le trioxyde d'arsenic).
