Explosive atmospheres - Part 38: Equipment and components in explosive atmospheres in underground mines (ISO/IEC 80079-38:2016)
ISO/IEC 80079-38:2016 is published as a dual logo standard and specifies the explosion protection requirements for the design, construction, assessment and information for use (maintenance, repair, marking) of equipment that may be an individual item or form an assembly. This includes machinery and components for use in mines susceptible to explosive atmospheres of firedamp and/or combustible
dust. The standard atmospheric conditions (relating to the explosion characteristics of the atmosphere) under which it may be assumed that equipment can be operated are:
- temperature -20 °C to 60 °C;
- pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar);
- and air with normal oxygen content, typically 21 % v/v. This part of ISO/IEC 80079 applies for equipment and components according to EPL Mb to be used in explosive atmospheres containing firedamp and/or combustible dust. For equipment and components according to EPL Ma, the requirements of this standard and of ISO 80079-36 and IEC 60079-0 apply. It is necessary to take account of external
conditions to the equipment which may affect the hazard and the resultant protection measures. These measures may include ventilation, gas detection or gas drainage. This part of ISO/IEC 80079 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. Detailed requirements and test procedures for the fire protection of conveyer belts are not part of this part of ISO/IEC 80079. Keywords: explosive atmospheres in underground mines, combustible dust
Explosionsfähige Atmosphären - Teil 38: Geräte und Komponenten in explosionsfähigen Atmosphären in untertägigen Bergwerken (ISO/IEC 80079-38:2016)
Diese Internationale Norm legt die explosionsschutztechnischen Anforderungen an die Konzeption, den Bau, die Bewertung und die Benutzerinformation (Instandhaltung, Reparatur, Kennzeichnung) der Geräte fest, die entweder Einzelstücke 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 gefährdet werden können. Die atmosphärischen Normbedingungen (bezogen auf die Explosionseigenschaften der Atmosphäre), unter denen angenommen werden kann, dass die Geräte betrieben werden, sind:
- Temperatur -20 °C bis +60 °C,
- Luftdruck 80 kPa (0,8 bar) bis 110 kPa (1,1 bar), und
- Luft mit einem Sauerstoffgehalt von üblicherweise 21 % Volumenanteile.
Diese Internationale Norm gilt für Geräte und Komponenten nach EPL Mb zur Verwendung in explosionsfähigen Atmosphären, die Grubengas und/oder brennbarem Staub enthalten.
ANMERKUNG In einigen Ländern könnte es Unterschiede hinsichtlich verschiedener Einteilungen geben, z. B. ist Mb ähnlich der Kategorie M 2 in der Europäischen Union.
Es ist notwendig, den äußeren Bedingungen der Geräte Rechnung zu tragen, die die Gefährdung und die daraus hervorgehenden Schutzmaßnahmen beeinflussen können. Diese Maßnahmen können Bewetterung, Gasmessung und Gasabsaugung beinhalten.
Diese Internationale 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.
Anforderungen und Prüfverfahren an die druckfeste Kapselung des Motors und die Flammensperren im Lufteinlass- und Abgassystem sind nicht Teil dieser Internationalen Norm.
Detaillierte Anforderungen und Prüfverfahren für den Brandschutz von Fördergurten sind nicht Teil dieser Internationalen Norm.
Atmosphères explosives - Partie 38: Appareils et composants destinés à être utilisés dans les mines souterraines grisouteuses (ISO/IEC 80079-38:2016)
ISO/IEC 80079-38:2016 est publiée en tant que norme sous double logo et spécifie les exigences relatives aux techniques de protection contre l'explosion au niveau de la conception, de la construction, de l'évaluation et des informations sur l'utilisation (maintenance, réparation et marquage) des appareils qui peuvent être des éléments individuels ou faire partie d'un assemblage. Ces appareils comprennent les machines et les composants prévus pour être utilisés dans les mines pouvant présenter des risques liés au grisou et/ou poussières combustibles. Les conditions atmosphériques normales (relatives aux caractéristiques de l'explosion de l'atmosphère), selon lesquelles il peut être pris pour hypothèse que les appareils peuvent fonctionner, sont les suivantes:
- température de -20 °C à 60 °C;
- pression de 80 kPa (0,8 bar) à 110 kPa (1,1 bar);
- et air à teneur normale en oxygène, généralement, typiquement 21 % v/v. La présente partie de l'ISO/IEC 80079 s'applique aux appareils et aux composants selon EPL Mb destinés à être utilisés en atmosphères explosives contenant le grisou et/ou les poussières combustibles. Les exigences de la présente norme, de l'ISO 80079-36 et de l'IEC 60079-0 s'appliquent aux appareils et aux composants selon EPL Ma. Les conditions externes doivent être prises en considération pour les appareils qui peuvent affecter les dangers et les mesures de protection qui en résultent. Ces mesures peuvent
inclure la ventilation, la détection de gaz et le captage de gaz. La présente partie de l'ISO/IEC 80079 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 l'appareil lorsque ces éléments pourraient représenter une source d'inflammation. L'échauffement provoqué par friction par exemple en raison d'une défaillance d'ordre mécanique ou du palier d'arbre peut enflammer la cage en plastique, le joint en plastique lui-même ou le lubrifiant. Les exigences détaillées et les procédures d'essai pour la protection contre l'incendie des courroies transporteuses ne font pas partie de la présente partie de l'ISO/IEC 80079.

Explanations:
A) Definitions
Minor and editorial changes clarification
decrease of technical requirements
minor technical change
editorial corrections
Changes in a standard classified as ‘Minor and editorial changes’ refer to changes regarding the
previous standard, which modify requirements in an editorial or a minor technical way. Also changes of
the wording to clarify technical requirements without any technical change are classified as ‘Minor and
editorial changes’.
A reduction in level of existing requirement is also classified as ‘Minor and editorial changes’
Extension addition of technical options
Changes in a standard classified as ‘extension’ refers to changes regarding the previous standard, which
add new or modify existing technical requirements, in a way that new options are given, but without
increasing requirements for equipment that was fully compliant with the previous standard. Therefore
these ‘extensions’ will not have to be considered for products in conformity with the preceding edition.
Major technical changes addition of technical requirements
increase of technical requirements
Changes in a standard classified as ‘Major technical change’ refer to changes regarding the previous
standard, which add new or increase the level of existing technical requirements, in a way that a
product in conformity with the preceding standard will not always be able to fulfil the requirements
given in the standard. ‘Major technical changes’ have to be considered for products in conformity with
the preceding edition. For every change classified as ‘Major Technical Change’ additional information is
provided in clause B) of the Annex ZC.
NOTE These changes represent current technological knowledge . However, these changes should not
normally have an influence on equipment already placed on the market.
