Specification for insulating materials based on mica -- Part 3: Specifications for individual materials -- Sheet 1: Commutator separators and materials

This sheet of IEC 60371-3 applies to several types of rigid materials based on mica splittings or mica paper for commutator separators. These products shall be made from muscovite or phlogopite mica, built up from mica splittings or mica paper by the use of a suitable bonding medium. They are supplied in the following forms:
– sheets in the dimensions in which they are pressed or after trimming;
– strips cut from sheets;
– commutator separators having the shapes and dimensions and in the conditions ordered
by the user. The normal manufacturing thicknesses lie between 0,3 mm and 2 mm.
Materials which conform to this specification meet established levels of performance.
However, the selection of material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.

Spécification pour les matériaux isolants à base de mica -- Partie 3: Spécifications pour matériaux particuliers -- Feuille 1: Matériaux pour entrelames de collecteurs

L'IEC 60371-3-1:2006 s'applique à divers types de matériaux rigides à base de clivures de mica ou de papier de mica utilisés pour réaliser des entrelames de collecteurs. Ces matériaux doivent être réalisés en mica muscovite ou en mica phlogopite à partir de clivures ou de papier de mica agglomérés à l'aide d'un agglomérant approprié. Ils sont fournis dans les formes suivantes: - feuilles aux dimensions de pressage ou après rectification; - bandes découpées dans ces feuilles; - entrelames de collecteurs réalisés aux dimensions, formes et conditions de la commande de l'utilisateur. L'épaisseur normale de fabrication se situe entre 0,3 mm et 2 mm. Cette troisième édition de la CEI 60371-3-1 remplace la deuxième édition parue en 1984, dont elle constitue une révision technique. Les principales modifications par rapport à l'édition antérieure portent sur les numéros des articles pour correspondre à la numérotation des articles de la dernière édition de la CEI 60371-2:2004. Mots clés: clivures de mica ou de papier de mica utilisés pour réaliser des entrelames de collecteurs, muscovite ou en mica phlogopite

SPECIFICATION FOR INSULATING MATERIALS BASED ON MICA –

Part 3: Specifications for individual materials – Sheet 1: Commutator separators and materials

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC Nati
