Reed switches - Part 1: Generic specification

This part of IEC 62246 which is a generic specification applies to all types of reed switches
including magnetically biased reed switches of assessed quality for use in general and
industrial applications.
NOTE 1 Mercury wetted reed switches are not covered by this standard due to their possible environmental
impact.
It lists the tests and measurement procedures which may be selected for use in detail
specifications for such reed switches.
This standard applies to reed switches which are operated by an applied magnetic field; it is
not restricted to any particular type of contact load.
For elementary relays with reed switches, this standard is recommended to be used together
with the standards IEC 61810-1, IEC 61811-1 as applicable.
For applications of reed switches, this standard is recommended to be used together with
specific product standards.
NOTE 2 Where any discrepancies occur for any reasons, documents rank in the following order of authority:
a) the detail specification,
b) the sectional specification,
c) the generic specification,
d) any other international documents (for example, of the IEC) to which reference is made.
The same order of precedence applies to equivalent national documents.

Reedschalter - Teil 1: Fachgrundspezifikation

Contacts à lames souples - Partie 1: Spécification générique

L'IEC 62246-1:2015, qui est une spécification générique, s'applique à tous les types de contacts à lames souples, y compris les contacts à lames souples polarisés magnétiquement ayant une qualité assurée pour être utilisés dans des applications générales et industrielles. Les contacts à lames souples mouillés au mercure ne sont pas couverts par la présente Norme en raison de leur possible impact sur l'environnement. Elle énumère les procédures d'essai et de mesure qui peuvent être sélectionnées pour être utilisées dans des spécifications particulières relatives à de tels contacts à lames souples. La présente Norme s'applique aux contacts à lames souples qui sont manoeuvrés par un champ magnétique appliqué; elle n'est restreinte à aucun type particulier de charge de contacts. Pour les relais élémentaires équipés de contacts à lames souples, il est recommandé d'utiliser la présente Norme conjointement avec les normes IEC 61810-1 et IEC 61811-1 selon le cas. Pour les applications des contacts à lames souples, il est recommandé d'utiliser la présente Norme conjointement avec les normes de produits spécifiques. La présente Norme annule et remplace la deuxième édition de l'IEC 62246-1 parue en 2011. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- ajout de l'introduction;
- mise à jour du domaine d'application, des termes et définitions, des valeurs assignées et de la procédure d'essai et de mesure;
- amélioration de l'essai diélectrique, des essais d'endurance électrique couvrant l'essai d'endurance électrique maximale et l'essai de surcharge;
- amélioration du Tableau F.1 pour les caractéristiques électriques assignées basées sur la classification;
- ajout du Tableau G.1 pour la puissance assignée en HP (horsepower) basée sur la classification.

Stikala reed - 1. del: Splošne zahteve

Ta del standarda IEC 62246, ki se nanaša na splošne zahteve, se uporablja za vse vrste stikal reed, vključno z magnetno pristranskimi stikali reed ocenjene kakovosti za uporabo v splošnih in industrijskih uporabah.
OPOMBA 1: Stikala reed z živim srebrom niso obravnavana v tem standardu zaradi njihovega možnega vpliva na okolje.
V standardu so navedeni preskusi in merilni postopki, ki jih je mogoče izbrati za uporabo v podrobnih specifikacijah za taka stikala reed. Ta standard se uporablja za stikala reed, ki jih upravlja uporabljeno magnetno polje; ni omejeno na posamezno vrsto kontaktne obremenitve.
Za osnovne releje s stikali reed je ta standard po potrebi priporočljivo uporabljati skupaj s standardoma IEC 61810-1 in IEC 61811-1. Za uporabe stikal reed se priporoča uporaba tega standarda skupaj s posebnimi standardi za proizvode.
OPOMBA 2: Kadar zaradi katerega koli razloga pride do neskladnosti, se dokumenti upoštevajo v naslednjem vrstnem redu:
a) podrobna specifikacija,
b) področna specifikacija,
c) rodovna specifikacija,
d) vsi drugi mednarodni dokumenti (na primer IEC), na katerega se sklicuje besedilo.
Enak vrstni red veljavnosti se uporablja za enakovredne nacionalne dokumente.
