Workplace exposure - Procedures for the determination of the concentration of chemical agents - Basic performance requirements

This document specifies basic performance requirements for procedures for the determination of the concentration of chemical agents in workplace atmospheres as required by the Chemical Agents Directive 98/24/EC [13]. These requirements apply to all steps of measuring procedures regardless of the physical form of the chemical agent (gas, vapour, airborne particles), measuring procedures with separate sampling and analytical methods, and direct-reading instruments.
This document specifies requirements that are fulfilled by measuring procedures when tested under prescribed laboratory conditions due to a wide range of environmental conditions encountered in practice.

Exposition am Arbeitsplatz - Verfahren zur Bestimmung der Konzentration von chemischen Arbeitsstoffen - Grundlegende Anforderungen an die Leistungsfähigkeit

Dieses Dokument legt grundlegende Anforderungen an die Leistungsfähigkeit von Verfahren zur Bestimmung der Konzentration chemischer Arbeitsstoffe in der Arbeitsplatzatmosphäre fest, wie seitens der Richtlinie über chemische Arbeitsstoffe 98/24/EG [13] gefordert. Diese Anforderungen sind für alle Schritte von Messverfahren, unabhängig vom physikalischen Zustand des chemischen Arbeitsstoffes (Gas, Dampf, luftgetragene Partikel), Messverfahren mit voneinander unabhängigen Probenahme- und Analyseverfahren sowie für direktanzeigende Messgeräte anzuwenden.
Dieses Dokument legt Anforderungen fest, die bei der Prüfung unter vorgeschriebenen Laborbedingungen aufgrund einer Vielzahl von Umgebungsbedingungen in der Praxis durch Messverfahren zu erfüllen sind.

Exposition sur les lieux de travail - Procédures pour déterminer la concentration d'agents chimiques - Exigences élémentaires relatives aux performances

Le présent document spécifie les exigences élémentaires de performances pour les procédures servant à déterminer la concentration des agents chimiques dans l'air des lieux de travail, comme requis par la Directive 98/24/CE relative aux agents chimiques [13]. Ces exigences s'appliquent à toutes les étapes des procédures de mesure, indépendamment de la forme physique de l'agent chimique (gaz, vapeur, particules en suspension dans l'air), aux procédures de mesure pour lesquelles le prélèvement et l'analyse sont deux étapes distinctes et aux instruments à lecture directe.
Le présent document spécifie les exigences auxquelles doivent satisfaire les procédures de mesure soumises à essai dans des conditions de laboratoire prescrites, ceci en raison du large éventail de conditions environnementales rencontrées dans la pratique.

Introduction
National laws and regulations require the assessment of the exposure of a worker to chemical agents in
workplace atmospheres. One way of assessing such exposure is to measure the concentration of a
chemical agent in the air in the worker's breathing zone. The procedures used for such measurements
should provide reliable and valid results for the comparison purpose of exposure measurements with
occupational exposure limit values (OELVs) and for the provision of acceptable control strategies.
This document introduces basic requirements to fulfil the measurement procedures in the process of
quantitative exposure assessment. Specific European Standards and International Standards have been
prepared for different types of measuring procedures and measuring devices. These include standards
for airborne particle samplers (EN 13205, all parts), diffusive samplers (EN 838 and ISO 16107),
pumped samplers (EN ISO 22065), short-term detector tubes (EN ISO 17621), personal sampling
pumps (EN ISO 13137), metals and metalloids in airborne particles (EN ISO 21832), mixtures of
airborne particles and vapour (EN 13936) and direct-reading instruments for toxic gases and vapours
(EN 45544, all parts). In these specific documents, additional requirements have been included for the
procedure or device in question, so that the basic requirements of this document are not compromised.
Where no specific European Standard and/or International Standard exist, only the basic requirements
apply.
Performance requirements given in this document are intended to apply under environmental
conditions present at the workplace. However, because a wide range of environmental conditions are
encountered in practice, this document specifies requirements that have to be fulfilled by measuring
procedures when tested under prescribed laboratory conditions.
It is the user's responsibility to choose the appropriate procedures or devices that meet the
requirements of this document. One way of doing this is to obtain information or confirmation from the
provider of a procedure or the manufacturer of a device. Type-testing or, more generally, assessment of
the performance of procedures or devices, can be undertaken by the manufacturer, user, testing house
or research and development laboratory, as is most appropriate. A number of existing procedures for
workplace measurements have either been tested over a part of the required minimum measuring
range, but not over the entire range, or have not been tested for all environmental influences and
potential interferences. If these partially validated procedures meet the performance requirements of
this document, they can be used at present. Nevertheless, these procedures should be tested over the
full ranges as soon as is reasonably practicable.
