Workplace atmospheres - Electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours - Part 1: General requirements and test methods

This European Standard specifies general requirements and test methods for the determination of the performance characteristics of personal, portable, transportable and fixed, continuous duty electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours in workplace atmospheres.

Arbeitsplatzatmosphäre - Elektrische Geräte für die direkte Detektion und direkte Konzentrationsmessung toxischer Gase und Dämpfe - Teil 1: Allgemeine Anforderungen und Prüfverfahren

Diese Europäische Norm legt allgemeine Anforderungen und Prüfverfahren für die Bestimmung des Be-triebsverhaltens von personenbezogenen, tragbaren, transportablen und ortsfesten kontinuierlich betriebenen elektrischen Geräten für die direkte Detektion und direkte Konzentrationsmessung toxischer Gase und Dämpfe in Arbeitsplatzatmosphären fest. Diese Europäische Norm ist anwendbar auf Geräte, deren primärer Zweck es ist, eine Anzeige, einen Alarm und/oder ein anderes Ausgangssignal abzugeben, um vor der Anwesenheit eines toxischen Gases oder Dampfes in der Atmosphäre zu warnen und in einigen Fällen automatische oder manuelle Schutzmaßnah¬men auszulösen. Sie ist anwendbar auf Geräte, bei denen der Sensor automatisch ein elektrisches Signal erzeugt, wenn Gas vorhanden ist. Diese Europäische Norm gilt nicht für Geräte, die eingesetzt werden: – zur Messung von Sauerstoff; – ausschließlich als Laboranalyse- oder Labormessgeräte; – ausschließlich zur Prozessmessung; – in Tiefgaragen und Tunneln; – im häuslichen Bereich; – zur Überwachung von Umweltluftverschmutzungen; – zur Messung brennbarer Gase und Dämpfe bezüglich des Explosionsrisikos. Sie gilt ebenfalls nicht für Geräte mit offener Messstrecke (Sichtlinie) zur Bereichsüberwachung. Bei Geräten zur Detektion mehrerer Gase gilt diese Norm ausschließlich für die Detektion toxischer Gase oder Dämpfe.

Introduction National laws and regulations based on European Directives require the assessment of the potential exposure of a worker to chemical agents in workplace atmospheres. EN 45544, Workplace atmospheres – Electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours, consists of the following parts: — Part 1: General requirements and test methods; — Part 2: Performance requirements for apparatus used for exposure measurement; — Part 3: Performance requirements for apparatus used for general gas detection; — Part 4: Guide for selection, installation, use and maintenance. EN 45544 series is based on EN 482 which specifies general performance requirements for procedures for measuring the concentration of chemical agents in workplace atmospheres. These performance requirements 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 fulfil
