EN 60079-35-1:2011

Explosive atmospheres - Part 35-1: Caplights for use in mines susceptible to firedamp - General requirements - Construction and testing in relation to the risk of explosion

IEC 60079-35-1:2011 specifies requirements for the construction, testing and marking of caplights, including caplights with a point of connection for other equipment, for use in mines susceptible to firedamp (Group I - electrical equipment for explosive gas atmospheres as defined in IEC 60079-0). It deals only with the risk of the caplight becoming a source of ignition. The requirements for performance are in IEC 60079-35-2. This standard supplements and modifies the general requirements of IEC 60079-0 except as indicated in Table 1. This first edition cancels and replaces the second edition of IEC 62013-1, published in 2005, and constitutes a full technical revision. The main technical differences with respect to the previious edition are: - the introduction of a means to achieve an equipment protection level (EPL) of Ma; - the introduction of a single clause relating to equipment construction replacing individual specific clauses for the headpiece, battery, cable and external charging contacts; - the deletion of statements relating to surface temperature, the rewording of statements relating to creepage and clearance and the addition of statements relating to thermal protection, electronic assemblies and additional circuitry; - specific referenc to lithium cells; - the addition of statements relating to battery recharging and protection against deep discharge.

Atmosphères explosives - Partie 35-1: Lampes-chapeaux utilisables dans les mines grisouteuses - Exigences générales - Construction et essais liés au risque d'explosion

La CEI 60079-35-1:2011 spécifie les exigences pour la construction, les essais et le marquage des lampes-chapeaux, y compris les lampes-chapeaux avec un point de connexion pour d'autres matériels, utilisables dans les mines grisouteuses (Groupe I - matériels électriques pour les atmosphères explosives gazeuses comme définies dans la CEI 60079-0). Elle traite uniquement du risque, présenté par une lampe-chapeau, de devenir une source d'inflammation. Les exigences d'aptitude à la fonction se trouvent dans la CEI 60079-35-2. La présente norme complète et modifie les exigences générales de la CEI 60079-0, excepté pour ce qui est indiqué dans le Tableau 1. Cette première édition annule et remplace la deuxième édition de la CEI 62013-1, parue en 2005, et constitue une révision technique générale. Les différences techniques principales par rapport à l'édition précédente sont: - l'introduction d'un article unique relatif à la construction du matériel, remplaçant les différents articles spécifiques pour le projecteur, la batterie, le câble et les contacts extérieurs de charge; - la suppression des indications concernant la température de surface, la reformulation des énoncés relatifs aux lignes de fuite et aux distances dans l'air, et l'adjonction d'indications concernant la protection thermique, les ensembles électroniques et les circuits additionnels; - une référence spécifique aux éléments au lithium; - l'adjonction d'indications concernant la recharge de la batterie et la protection contre la décharge sévère.

Rudarske naglavne svetilke za uporabo v rudnikih, kjer se lahko pojavi jamski eksplozivni plin - 1. del: Splošne zahteve - Konstruiranje in preskušanje zaradi tveganja eksplozije (IEC 60079-35-1:2011)

Ta del IEC 60079-35 določa zahteve za konstruiranje, preskušanje in označevanje rudarskih naglavnih svetilk, vključno z rudarskimi naglavnimi svetilkami s priključkom za drugo opremo, za uporabo v rudnikih, kjer se lahko pojavi jamski eksplozivni plin (skupina I – električna oprema za eksplozivne plinske atmosfere, kot je opredeljeno v IEC 60079-0). Obravnava le tveganje, da bi rudarska naglavna svetilka postala vir vžiga. Zahteve za delovanje so navedene v IEC 60079-35-2.1. Ta standard dopolnjuje in spreminja splošne zahteve IEC 60079-0, razen kot je navedeno v preglednici 1. Kjer zahteva tega standarda nasprotuje zahtevi IEC 60079-0, imajo zahteve tega standarda prednost. Skladnost s tem standardom zagotavlja EPL Mb (glej točko 4.1 tega standarda). Če je zahtevan EPL Ma, mora rudarska naglavna svetilka ustrezati zahtevam iz točke 4.2 tega standarda, ki se sklicuje na IEC 60079-11. Pričakuje se, da rudarske naglavne svetilke, ki ustrezajo temu standardu (EPL Mb), občasno obratujejo v atmosferah, kjer jamski eksplozivni plin presega zakonske ravni, pri katerih je treba ljudi odstraniti iz atmosfere z veliko količino jamskega eksplozivnega plina v varno območje. Pri načrtovanju opreme za obratovanje v pogojih, ki niso navedeni zgoraj, se ta standard lahko uporablja kot vodilo, lahko pa je potrebno dodatno preskušanje. Kadar je rudarska naglavna svetilka ocenjena kot intrinzično varna oprema, Ex ia, v skladu z IEC 60079-11, je treba uporabiti le točke/podtočke, navedene v 4.2.

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 change 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 ZY.
Note: These changes represent current technological knowledge . However, these changes should not
normally have an influence on equipment already placed on the market.
B) Information about the background of ‘Major Technical Changes’
None.
Instructions:
The manufacturer or his authorised representative in the Community is to draw up the instructions for use
in the required Community languages.
Marking:
The marking in this standard is to be supplemented/modified by the marking according to Directive
94/9/EC. Examples are given below.

(informative)
Coverage of essential requirements of the directive 94/9/EC

This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and within its scope the standard covers only the
following essential requirements and out of those given in Annex II of the Directive 94/9/EC:

- ER 1.0.1 to ER 1.0.6;
- ER 1.1.1 to ER 1.1.3;
- ER 1.2.1 to ER 1.2.9;
- ER 1.3.1 to ER 1.3.5;
- ER 1.4.1 to ER 1.4.2;
- ER 2.0.1.1 to ER 2.0.1.4;
- ER 2.0.2.1 to ER 2.0.2.3;
Compliance with this standard provides one means of conformity with the specified essential
requirements of the Directive concerned.
