EN 60086-3:2016

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 60086-3:2016 spécifie les dimensions, la désignation, les méthodes d'essai et les exigences applicables aux piles électriques pour montres. Dans certains cas, un choix de méthodes d'essai est proposé. Lorsque le fabricant présente les caractéristiques électriques et/ou les performances de la pile, il précise la méthode d'essai qui a été utilisée. Cette quatrième édition annule et remplace la troisième édition parue en 2011. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - Harmonisation des tailles des éléments et des essais de capacité avec l'IEC 60086-2; - Clarification des Articles 6: Echantillonnage et assurance de la qualité, 7: Méthodes d'essai, et 8: Examen visuel et conditions d'acceptation; - Harmonisation des conditions de température et d'humidité avec celles de l'IEC 60086-1. La présente norme est une norme double logo. Mots clés: piles électriques pour montres

Primarne baterije - 3. del: Baterije za zapestne ure (IEC 60086-3:2016)

Standard IEC 60086-3:2011(E) opredeljuje mere, označevanje, preskusne metode in zahteve za primarne baterije za zapestne ure. V številnih primerih je podan meni s preskusnimi metodami. Pri predstavitvi električnih lastnosti in/ali podatkov o delovanju proizvajalec navede, katera preskusna metoda je bila uporabljena. Glavne tehnične spremembe v primerjavi s prejšnjo izdajo so risbe, pregled razpredelnice z elektrokemičnimi sistemi in uskladitev točke o označevanju z drugimi standardi iz skupine IEC 60086. Poleg tega so bile razpredelnici z ravnmi uhajanja dodane nazornejše risbe. Ta publikacija je objavljena kot standard z dvojnim logotipom.
