(Main)Equipment and components intended for use in potentially explosive atmospheres in underground mines
Equipment and components intended for use in potentially explosive atmospheres in underground mines
This European Standard specifies the explosion protection requirements for the construction and marking of equipment that may be an individual item or form an assembly. This includes machinery and components placed on the market by a single supplier for use in mines susceptible to explosive atmospheres of firedamp and/or combustible dust (at atmospheric conditions as defined in EN 1127-2).
NOTE 1 This European Standard deals only with the ignition protection of mining machinery and manufacturers will need to take account of all other relevant EU Directives relating to the construction of machines e.g. the consolidated Machinery Directive 98/37/EC. Additionally, manufacturers will need to take account of any national legislation in the country where they intend to market their equipment.
NOTE 2 Where the flammable gas in the atmosphere is not predominantly methane, reference will need to be made to 4.1 in either EN 60079-0:2004 or EN 13463-1:2001.
NOTE 3 The definition of ‘equipment’ is contained in EN 13463-1. The definition of ‘assembly’ can be found the ATEX guidelines, published by the European Commission.
Equipment complying with the relevant clauses of this European Standard is considered to meet the requirements for equipment of Group I - Category M2.
This European Standard also deals with the prevention of ignitions of explosive atmospheres caused by burning (or smouldering) of combustible material such as fabric fibres, plastic O-rings, rubber seals, lubricating oils or greases used in the construction of the equipment if such items could be an ignition source. For example, the mechanical failure of rotating shaft bearings can result in frictional heating that ignites its plastic cage, plastic seal or lubricating grease. See also 5.2.4 of EN 13463-1:2001.
Geräte und Komponenten für den Einsatz in schlagwettergefährdeten Bereichen von untertägigen Bergwerken
Diese Europäische Norm legt die explosionsschutztechnischen Anforderungen an den Bau und die Kennzeichnung von Geräten fest, die separate Gegenstände sein können oder Baugruppen bilden. Dies schließt Geräte und Komponenten ein, die von einem einzelnen Lieferanten in Verkehr gebracht werden und die für die Verwendung in Bergwerken vorgesehen sind, die durch Grubengas und/oder brennbare Stäube (unter atmosphärischen Bedingungen - wie in EN 1127-2 definiert) gefährdet werden können.
ANMERKUNG 1 Diese Europäische Norm beschäftigt sich nur mit dem Zündschutz von Bergbaumaschinen. Die Hersteller haben alle anderen relevanten EG-Richtlinien in Betracht zu ziehen, die die Konstruktion von Maschinen betreffen, wie z. B. die fortentwickelte Maschinerichtlinie 98/37/EG. Zusätzlich ist es erforderlich, dass die Hersteller die jeweilige nationale Gesetzgebung in dem Land in Betracht ziehen, in dem sie ihre Geräte vermarkten wollen.
ANMERKUNG 2 Enthalten die Wetter nicht vorwiegend Methan als brennbares Gas, ist ein Hinweis zu 4.1 von
EN 60079-0:2004 oder EN 13463-1:2001 erforderlich.
ANMERKUNG 3 Die Definition von 'Gerät' ist in EN 13463-1 enthalten.
Geräte, die den entsprechenden Abschnitten der vorliegenden Europäischen Norm entsprechen, erfüllen die Anforderungen für die Geräte der Gruppe I - Kategorie M2.
Diese Europäische Norm behandelt auch die Vermeidung von Zündungen von explosionsfähigen Atmosphären durch Brände (oder Glimmbrände) von brennbaren Materialien wie Gewebefasern, Kunststoff-"O"-Ringen, Gummidichtungen, Schmierölen oder -fetten, die in der Konstruktion benötigt werden, wenn solche Teile eine Zündquelle sein könnten. Z. B. kann Reibungshitze durch einen mechanischen Fehler oder rotierende Wellenlager den Plastikkäfig, die Plastikdichtung selbst oder das Schmierfett entzünden. Siehe auch 5.2.4 von EN 13463-1:2001.
ANMERKUNG 4 Der o.g. Abschnitt der EN 13463 1 fordert eine Bewertung der Zündgefahr auch für die Komponenten, die im Falle eines Fehlers in d
Appareils et composants destinés à être utilisés dans les mines souterraines grisouteuses
La présente Norme européenne spécifie les exigences relatives aux techniques de protection contre l’explosion au niveau de la construction et du marquage des appareils (éléments individuels ou faisant partie d’un assemblage). Ceci comprend les appareils et les composants qui sont mis en circulation par un fournisseur en particulier et qui sont prévus pour être utilisés dans les mines pouvant présenter des risques liés au grisou et / ou poussières inflammables (dans certaines conditions d’atmosphères, comme défini dans la norme EN 1127-2).
NOTE 1 La présente Norme européenne traite uniquement de la protection des machines utilisées dans les mines. Les fabricants doivent prendre en compte toutes les autres directives européennes pertinentes concernant la construction de machines comme par exemple la directive Machines européenne amendée 98/37/EG. De plus, les fabricants devront prendre en compte tous les autres textes réglementaires nationaux en vigueur dans les pays où sont commercialisés leurs appareils.
NOTE 2 Si le gaz inflammable dans l’atmosphère n’est pas principalement du méthane, se reporter au 4.1 de l’EN 60079-0:2004 ou à l’EN 13463-1:2001.
NOTE 3 Le terme « appareil » est défini dans l’EN 13463-1.
Les appareils répondant aux dispositions de la présente Norme européenne sont considérés comme satisfaisant aux exigences relatives aux appareils du Groupe I - Catégorie M2.
La présente Norme européenne traite également de la prévention des inflammations des atmosphères explosives provoquées par la combustion (ou le feu couvant) de matériaux combustibles tels que les fibres textiles, les joints toriques en matières synthétiques, les joints d’étanchéité en caoutchouc, les huiles et graisses de lubrification qui sont nécessaires à la machine lorsque ces éléments peuvent représenter une source d’inflammation. L’échauffement provoqué par frottement par exemple en raison d’un défaut d’ordre mécanique ou du palier d’arbre peut enflammer la cage en plastique, le jo

Foreword
This European Standard (EN 1710:2005) has been prepared by Technical Committee CEN/TC 305
“Potentially explosive atmospheres - Explosion prevention and protection”, the secretariat of which is held by
DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the
latest by May 2006.
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this
European Standard.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

and the United Kingdom.
Introduction
This European Standard specifies requirements for the constructional features of equipment and components
that may be an individual item or form an assembly, to enable them to be used in mines, or parts of mines,
susceptible to explosive atmospheres of firedamp and/or combustible coal dust.
Most of the electrical equipment used on mining machinery is certified as an individual item of equipment e.g.
the motor, switchgear etc., and meets its own marking requirements. This Notified Body Certification, however,
does not deal with the interconnection of these items of equipment by cables or the machine electrical power
system as an entity. In order to comply with 1.6.4 of the Essential Safety Requirements of the ATEX Directive
(94/9/EC), the equipment and components including their interconnections should be assessed, from an
ignition point of view, by the manufacturer.
Both non-electrical equipment and the interconnection of electrical/non-electrical equipment require an ignition
hazard risk assessment to satisfy the Essential Health and Safety requirements of the ATEX Directive and be
put in the appropriate declaration of conformity document.
Therefore, it is necessary that not just the equipment, but all its parts, is examined by the manufacturer
according to a formally documented hazard assessment that establishes and lists all the possible ignition
sources of the equipment including the cables an
