(Main)Requirements for design and testing of vacuum cleaners for use in potentially explosive atmospheres
Requirements for design and testing of vacuum cleaners for use in potentially explosive atmospheres
This European Standard specifies requirements for design, construction, testing and marking of
handheld, portable and transportable vacuum cleaners and dust collectors, including their
accessories, constructed to Group II categories 2G and 3G and to Group II categories 2D and 3D,
intended for the collection of combustible or non-combustible dusts and flammable or non260
flammable liquids in potentially explosive atmospheres. A potentially explosive atmosphere may be
generated by the equipment during its intended use. It covers equipment driven by electricity and
by pneumatic power.
This European Standard deals with all significant hazards, hazardous situations and events
relevant to vacuum cleaners and dust collectors, when they are used as intended and under
conditions of misuse which are reasonably foreseeable by the manufacturer.
Typical applications for the concerned equipment are:
- Collection of dust produced by machinery at the point of generation
- General housekeeping around machinery and of working areas
- And/or collection of spills.
For other specific applications a specific assessment shall be performed.
This European Standard does not cover equipment used to collect toxic dusts where there is a
health risk if dust passes through the filter element. This European Standard does not cover either
the collection of dusts which have explosive and unstable properties (UN transport class 1, class
4.1 and class 5.2).
This European Standard covers vacuum cleaners with an internal dust loaded volume of maximum
200 liters
This European Standard does not apply to pumps, where the inlet nozzle is submerged into a
liquid, and all conveying applications.
This European Standard does not apply to Group I vacuum cleaners and dust collectors for mining.
For an easier readability, all types of equipment concerned by this standard are referred as
“Vacuum cleaner” in this document.
NOTE Where undated references are used in the body of the standard the latest edition
applies
Anforderungen an die Konstruktion und Prüfung von Staubsaugern zur Verwendung in explosionsgefährdeten Bereichen
Dieses Dokument legt die Gestaltungs-, Konstruktions-, Prüf- und Kennzeichnungsanforderungen für handgehaltene,tragbare und transportable Industriesauger sowie deren Zubehör fest, die entsprechend Gruppe II, Kategorie 2G oder Kategorie 3G (der Explosionsgruppen IIA, IIB, IIB plus Wasserstoff) sowie Gruppe II, Kategorie 2D und Kategorie 3D (der Explosionsgruppe IIIA, IIIB und IIIC) konstruiert werden und für die Sammlung von brennbarem oder nicht brennbarem Staub und brennbaren oder nicht brennbaren Flüssigkeiten in explosionsgefährdeten Bereichen bestimmt sind. Durch den bestimmungsgemäßen Gebrauch des Gerätes könnte ein explosionsgefährdeter Bereich erzeugt werden.
ANMERKUNG 1 Die Ansammlung von 1 mm oder mehr brennbarem Staub auf Oberflächen in einem Arbeitsbereich kann eine explosionsfähige Atmosphäre erzeugen (siehe Literaturhinweis zu 1/32 in. of Depth of Dust Accumulation for Guidance for Area Electrical Classification in NFPA 654, 2017 Edition).
Dieses Dokument ist anzuwenden für Geräte, die mit elektrischen und mit pneumatischen Antriebssystemen angetrieben werden.
Dieses Dokument enthält Vorgaben für den Umgang mit wesentlichen Gefährdungen, Gefährdungssituationen und/oder Gefährdungssituationen mit Bezug zu Industriesaugern, wenn sie bestimmungsgemäß und unter Bedingungen von durch den Hersteller vernünftigerweise vorhersehbaren Fehlanwendungen verwendet werden.
Typische Anwendungsbereiche für die betroffenen Geräte sind:
— Sammlung von durch Maschinen erzeugten Staub am Ort der Erzeugung;
— allgemeine Reinigung im Bereich um Maschinen und von Arbeitsbereichen; und/oder
— Sammlung von verschütteten Substanzen;
— Reinigung der Geräte bei Wartungsarbeiten; und/oder
— Sammlung von spezifischem Abfall.
Für die Staubaufnahme bei Vorhandensein von brennbaren Flüssigkeiten oder Dämpfen wird eine spezifische Risikobeurteilung durchgeführt, wenn dies Teil der vorgesehenen Einsatzbedingungen des Industriesaugers ist und zusätzliche Vorsichtsmaßnahmen, die über das in diesem Dokument beschriebene Maß hinausgehen, erforderlich sein können.
ANMERKUNG 2 Beim Durchströmen von Staub durch einen Industriesauger entstehen hohe elektrostatische Aufladungen, die in den meisten Situationen eine potenzielle Zündquelle für eine brennbare Gas- oder Dampfatmosphäre darstellen.
Für das Aufsaugen von brennbaren Flüssigkeiten mit geringer Leitfähigkeit wird eine spezifische Risikobeurteilung durchgeführt, wenn dies Teil der vorgesehenen Einsatzbedingungen des Industriesaugers ist und zusätzliche Vorsichtsmaßnahmen, die über das in diesem Dokument beschriebene Maß hinausgehen, erforderlich sein können.
ANMERKUNG 3 Die daraus resultierenden Flüssigkeitsgeschwindigkeiten liegen wahrscheinlich über den Grenzwerten, die erforderlich sind, um die elektrostatische Aufladung nach CLC/TR 60079 32 1:2018 auf einem nicht gefährlichen Niveau zu halten.

1 Scope
This document specifies requirements for design, construction, testing and marking of hand-held,
portable and transportable vacuum cleaners, including their accessories, constructed to Group II,
categories 2G or 3G (of explosion groups IIA, IIB, IIB plus hydrogen), and to Group II, categories 2D or 3D
(of explosion groups IIIA, IIIB and IIIC), intended for the collection of combustible or non-combustible
dusts and flammable or non-flammable liquids in potentially explosive atmospheres. A potentially
explosive atmosphere could be generated by the equipment during its intended use.
NOTE 1 The accumulation of 1 mm or more of combustible dust on surfaces in a working area can create an
explosive atmosphere (see reference to 1/32 in. of Depth of Dust Accumulation for Guidance for Area Electrical
Classification in NFPA 654, 2017 Edition).
This document applies to equipment driven by electric power and by pneumatic power.
This document gives guidelines for dealing with significant hazards, hazardous situations and/or events
relevant to vacuum cleaners when they are used as intended and under conditions of misuse which are
reasonably foreseeable by the manufacturer.
Typical applications for the concerned equipment are:
— collection of dust produced by machinery at the point of generation;
— general housekeeping around machinery and of working areas; and/or
— collection of spills;
— cleaning of equipment during maintenance operations; and/or
— collection of specific waste.
For the collection of dust in the presence of flammable liquids or vapours, a specific risk assessment is
performed if this is part of the vacuum cleaners intended conditions of use and additional precautions
beyond what is described in this document can be required.
NOTE 2 The passage of dust through a vacuum cleaner will generate high levels of electrostatic charge which, in
most situations, will be a potential source of ignition to a flammable gas or vapour atmosphere.
For the collection of low-conductivity flammable liquids, a specific risk assessment is performed if this is
part of the vacuum cleaners intended conditions of use and additional precautions beyond what is
described in this document can be required.
NOTE 3 The resulting liquid velocities are likely to be in excess of the limits required to maintain electrostatic
charge generation at a non-hazardous level according to CLC/TR 60079-32-1:2018.
This document does not apply to equipment used to collect toxic dusts where there is a health risk if dust
passes through the filter elements. This document does not apply to the collection of dusts which have
explosive and unstable properties (UN transport class 1, class 4.1 and class 5.2).
NOTE 4 Hazards related to the use of vacuum cleaners for the collection of hazardous dusts are the subject of
other standards.
This document applies to vacuum cleaners with an internal dirty air volume of maximum 250 l.
NOTE 5 250 l is the volume above which it is recognized a vacuum cleaner might not be considered as
transportable by an operator, and above which additional explosion protections can be required.
The present version of the document does not apply to battery operated equipment.
NOTE 6 Battery operated equipment might be part of the scope of this document in a subsequent version.
