(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 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.
This document does not apply to vacuum trucks.
This document applies to vacuum cleaners of canister and back-pack types. This document does not apply to upright vacuum cleaners.
This document does not apply to motorized cleaning head accessories.
NOTE 7 This document does not apply to household appliances which are the subject of other standards.
This document does not apply to applications where the substances are conveyed into a separate receiving container.
This document does not apply to equipment intended for use in underground parts of mines as well as those parts of surface installations of such mines endangered by firedamp and/or combustible dust.

Anforderungen an die Konstruktion und Prüfung von Industriesaugern 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.

4 Safety requirements and protective measures
4.1 General
All vacuum cleaners shall comply with the requirements contained in EN ISO 80079-36:2016 for non-
electrical equipment or non-electrical part(s) of electrical equipment unless otherwise stated in this
document. EN ISO 80079-36:2016 specifies the requirements for the design and construction of
equipment intended for explosive atmospheres in conformity with all Equipment Protection Levels
(EPLs) of Group II and III. It supplements and modifies the general requirements of
2 3
EN IEC 60079-0:2018 , as shown in Table 1 of EN ISO 80079-36:2016 . Where a requirement of
3 2
EN ISO 80079-36:2016 conflicts with a requirement of EN IEC 60079-0:2018 , as far as applicable for
non-electrical equipment, the requirement of EN ISO 80079-36:2016 takes precedence, unless
otherwise stated in this document.
All vacuum cleaners, within the scope of this document, shall comply with the safety requirements and
protective measures of Clause 4, Clause 5 and Clause 6.
NOTE Annex A presents a methodological approach to identify the applicable safety requirements and
protective measures for the vacuum cleaner.
4.2 Risk assessment
An ignition hazard assessment according to EN 1127-1:2019 and EN ISO 80079-36:2016 shall be
carried out and documented (see Annex D). Where, due to the specific intent of use, additional hazards
could occur a further risk assessment shall be carried out according to EN 1127-1:2019 due to nature of
substances to collect. An electrical power source will contain generally at least some potential ignition
hazards due to non-electrical parts, as a consequence, application of EN ISO 80079-36:2016 is required
A list of significant hazards, hazardous situations and events according to EN ISO 12100:2010, identified
by a risk assessment as significant for the machines specified in the scope and which require action to
eliminate or reduce the risk, is given in Annex E. A risk assessment for significant hazards, hazardous
situations and/or events according to EN ISO 12100:2010 shall be carried out and documented where,
due to the specific intended use, such as the collection of hybrid mixtures, additional hazards could occur.
The air loaded, with the dust or liquid and gas collected, and drawn into the vacuum cleaner from the
hazardous atmosphere, is released in the adjacent environment around the equipment through the air
path. Release of flammable substances shall therefore also be considered in the ignition hazard
assessment for the external part of the vacuum cleaner.
NOTE Refer to EN 1127-1:2019 for further information about hybrid mixture.
4.3 Assignment of categories
Vacuum cleaners which are used to collect and convey dusts or liquids in an explosive atmosphere are
assigned a category depending on the likelihood of them acting as an effective ignition source. The
category assignment concerns the part of the vacuum cleaner in contact with the explosive atmosphere.
NOTE 1 For definitions of equipment Categories 2 and 3, see EN 1127-1:2019.
Normal operating conditions shall be considered to occur in situations where the vacuum cleaner
performs its intended use within its design parameters. This includes conditions where stones, metal
particles and other solid or liquid substances could be drawn into the machine. This also includes
conditions during start up, shut down and emptying the collection tank.
Foreseeable malfunctions (such as a breakdown of seals, flange gaskets or releases of substances caused
by accidents or lack of maintenance observance) which involve repair or shut down are not considered
to be part of normal operation.
NOTE 2 For further information regarding relationship between categories and Equipment Protection Levels
(EPLs), see EN ISO 80079-36:2016 .
4.4 Assignment of types and applicable requirements
Vacuum cleaners have either an electrical or a non-electrical power source. The power sources can be
combined with 3 different collectors as shown in Table 1 based on the substances the vacuum cleaners
are designed to collect. Instructions for safe use need to identify the proper selection of equipment
according to the application, the characteristics of the flammable substances and potential external
influences
Vacuum cleaners are assigned a type based on the power source and the collector.

5 Safety requirements regarding ignition hazards
5.1 Requirements applicable to all types of vacuum cleaners
5.1.1 Hot surfaces
5.1.1.1 Maximum surface temperature
The maximum surface temperature of the vacuum cleaner is characterized by the hottest part of the
equipment that can come into contact with the explosive atmosphere or the maximum temperature of
the airflow which can act as an ignition source.
The maximum surface temperature of the vacuum cleaner is determined under the most adverse
conditions. Measurements shall be performed on both the external part and the internal part of the
vacuum cleaner. Foreseeable misuse of the vacuum cleaner and possible faults of components in contact
with the flammable substances shall be taken into account.
Reduction of surface temperatures by means of thermal insulation is not permitted.
Temperature measurements shall be made according to EN ISO 80079-36:2016 , for vacuum cleaners
driven by both electrical power or pneumatic power.
3 2
Where a requirement of EN ISO 80079-36:2016 conflicts with a requirement of EN IEC 60079-0:2018 ,
as far as applicable for non-electrical equipment, the requirement of EN ISO 80079-36:2016 takes
precedence.
Equipment may reach different service temperatures in different parts as defined by
EN ISO 80079-36:2016 .
When a fan is used, the maximum surface temperature of both the inside and outside parts of the fan that
can come into contact with the explosive atmosphere shall be determined.
NOTE Further information on the design and testing of the fan can be found in EN 14986.
5.1.1.2 Temperature classification
Vacuum cleaners shall be classified according to EN ISO 80079-36:2016 :
a) with a temperature class in accordance with Table 3 for Category 3G or 2G; or
b) by the maximum surface temperature for Category 3G, 2G, 3D or 2D for both the external and internal
part of the vacuum cleaner.
In addition, the maximum surface temperature marked for the internal part of the vacuum cleaner shall
be the greater of either:
— the maximum surface temperature determined in accordance with EN ISO 80079-36:2016
including the appropriate safety margins for the different categories; or
— the maximum temperature of the air flow with a safety margin of 20 % (with temperatures measured
in °C).
NOTE This safety margin of 20 % has been chosen because of the enhanced ignition risk at higher gas
temperatures. For further information, see EN 1127-1:2019.
Table 3 — Classification of maximum surface temperatures for Group II vacuum cleaners
Temperature class Maximum surface temperature
(°C)
T1 450
T2 300
T3 200
T4 135
T5 100
T6 85
5.1.2 Thermal endurance
5.1.2.1 Parts of the vacuum cleaner relevant for explosion protection
For enclosures and parts of enclosures of non-metallic materials on which the type of protection depends,
tests for thermal endurance shall be performed according to EN ISO 80079-36:2016 , 8.4.
5.1.2.2 Parts of the vacuum cleaner non-specifically relevant for explosion protection
For parts of the vacuum cleaner non-specifically relevant for explosion protection, continuous operating
temperature range of the materials the vacuum cleaner is made of, shall correspond to the maximum and
to the minimum temperatures they will be exposed during use, so the properties of the material do not
deteriorate over time.
Filters in the collection tank shall be made of non-flame propagating material.
The maximum temperature of the airflow and the temperature of the substances the vacuum cleaner is
designed to collect, such as hot particles, shall be taken into account.
Verification shall be performed by checking the relevant documentation and drawings, by inspecting the
materials the vacuum cleaner is made of, and by proceeding with measurement and functional testing.
5.1.3 Flames and hot gases
Vacuum cleaners which have a risk of producing flames or hot gases (e.g. those intended for the collection
of substances with low flash points or dusts with low MIE) shall be designed in conformance with the
requirements for relevant categories indicated in EN 1127-1:2019, 6.4.3 and with other requirements as
applicable and specified in EN 1127-1:2019.
If it has been determined the flammable substance collected by the vacuum cleaner can produce a flame,
installation of a flame arrester at the working air exhaust of the vacuum cleaner is a known solution.
Flame arresters shall comply with EN ISO 16852:2016 and their use shall comply with
CEN/TR 16793:2016.
If it has been determined the flammable substance collected by the vacuum cleaner can produce a
deflagration, installation of a rupture disk on the collection tank of the vacuum cleaner is a known
solution. Rupture disks shall comply with EN ISO 4126-2:2019 and their design shall comply with
EN 14797:2006.
The materials used for the impeller and fan casing shall withstand short-term exposure to flames.
When a flame arrester or a rupture disk is installed on the vacuum cleaner it shall be ensured the design
prevent all hazards to the operator when these devices are activated.
Verification shall be performed by checking the relevant documentation and drawings, by inspecting the
devices, and by proceeding with measurement and functional testing.
5.1.4 Mechanically generated sparks
5.1.4.1 General
Sparks generated by friction and mechanical impact could occur during collection of air, dust, solid parts
or a combination of this.
The vacuum cleaner shall be designed to prevent this hazard at intended use and foreseeable misuse.
The vacuum cleaner shall comply with EN ISO 80079-36:2016 , 6.4 to avoid mechanically generated
sparks.
If any, limitations of the intended use minimizing the risk shall be clearly specified in the instruction for
use.
NOTE Typical examples are brass stop baffle at suction inlet to reduce velocity of parts and radial suction inlet.
5.1.4.2 Fans
This clause applies to fans and impellers, as rotating parts of fans, in contact with the potentially explosive
atmosphere or the airflow containing combustible substances.
Fans located in the cooling airflow shall comply with EN IEC 60079-0:2018 , 17.2.3.
Fans in contact with the working air, typically with an absolute pressure at inlet below 0,8 bar, shall
comply with the requirements of this clause and 5.1.4.3 to prevent mechanically generated sparks.
NOTE 1 The vacuum cleaner typically operates at absolute pressure above 0,8 bar and below 1,1 bar. Internal
pressure resistance in the suction hose and throughout the filters at nominal airflow results in a situation where
fans in contact with the working air typically operate at an absolute pressure below 0,8 bar.
Fans shall be of rigid design. This requirement is considered as fulfilled for casings, supporting structures,
guards, protective devices and other external parts if the deformation resulting from an impact test at the
most vulnerable point is so small that the moving parts do not come into contact with the casing. Test for
resistance to impact shall be carried out in accordance with EN ISO 80079-36:2016 , 8.3.1.
The minimum clearance between rotating elements and the fan casing shall always be at least 0,5 % of
the relevant contact diameters (diameter of a rotating part at the point where it can contact a stationary
part) of the finished component, but shall not be less than 2 mm in the axial or radial directions nor need
be more than 13 mm. The clearance control method and approval range at standstill shall be included in
the operation and maintenance manual.
Impellers shall be of a rigid design and shall be able to withstand a test run at a minimum of 1,15 times
the maximum operational rotating speed for at least 60 s without causing an ignition risk, i.e. the impeller
shall not contact the casing. This test shall be performed after the impact test as specified in
EN ISO 80079-36:2016 , 8.3.1.
