EN 60086-3:2011

Primary batteries - Part 3: Watch batteries

IEC 60086-3:2011(E) specifies dimensions, designation, methods of tests and requirements for primary batteries for watches. In several cases, a menu of test methods is given. When presenting battery electrical characteristics and/or performance data, the manufacturer specifies which test method was used. The major technical changes with respect to the previous edition are the drawings, a review of the table of electrochemical systems and a harmonization of the marking clause with the other standards of the IEC 60086 series. Moreover, the table of the leakage levels was extended by adding drawings with better visualization. This publication is published as a double logo standard.

Primärbatterien - Teil 3: Uhrenbatterien

Piles électriques - Partie 3: Piles pour montres

L'IEC 60086-3:2011 spécifie les dimensions, la désignation, les méthodes d'essais et les exigences pour les piles électriques pour montres. Dans plusieurs cas, il est proposé des options pour les méthodes d'essai. Lorsque le fabricant présente les caractéristiques électriques et/ou les performances de la pile, il précise la méthode d'essai utilisée. Cette troisième édition annule et remplace la deuxième édition (2004) et constitue une révision technique. Les principales modifications techniques par rapport à l'édition précédente sont les dessins, une révision du tableau des systèmes électrochimiques et une harmonisation de l'article relatif au marquage avec les autres normes de la série CEI 60086. De plus, le tableau concernant les niveaux de fuite a été enrichi par l'ajout de dessins avec une meilleure visualisation. La présente publication est une norme double logo. Le contenu du corrigendum de Septembre 2011 ont été inclus dans cette copie. La présente version bilingue (2014-01) correspond à la version anglaise monolingue publiée en 2011-01. Mots clés: d'essais et les exigences pour les piles électriques pour montres

Primarne baterije - 3. del: Baterije za zapestne ure (IEC 60086-3:2011)

Ta del IEC 60086 določa mere, označevanje, metode preskušanja in zahteve za primarne baterije za zapestne ure. V več primerih je naveden cel meni preskusnih metod. Proizvajalec mora pri predstavljanju električnih značilnosti baterij in/ali podatkov o delovanju navesti uporabljeno preskusno metodo.
