Specification for insulating materials based on mica - Part 2: Methods of test
Defines the methods of test which are applicable to built-up mica materials, products based on them and mica paper. The main changes from the previous edition are as follows: a) All clauses re-numbered. b) Relevant template of ISO 67 has been added to this standard as Annex A. c) Clause 8: Tensile strength and elongation at break Procedure modified to give rate of movement instead of time limit. Different rate of movement for raw mica as opposed to reinforced and/or impregnated mica. d) Clause 11: Stiffness Size of test specimen revised. Wording modified so that standard covers materials using carriers other than woven glass cloth and materials that are 3-ply. Revision of terms machine direction and transverse direction. (These were incorrect in second edition (1987).) e) Clause 13: Elastic compression and plastic compression Tolerance on measurement of height of stack changed to within 0,01 mm. Times for change in pressure in procedure changed to 1 min. f) Clause 16: Electric strength Modified in line with Amendment 1 (1994) to the second edition (1987). Changes relate to latest edition of EN 60243-1. g) Clause 19: Detection of defects and conductive particles Revised subclause.
Bestimmung für Isoliermaterialien aus Glimmer - Teil 2: Prüfverfahren
Spécification pour les matériaux isolants à base de mica - Partie 2: Méthodes d'essais
Définit les méthodes d'essais qui sont applicables aux matériaux à base de mica, aux produits qui en sont issus et au papier de mica. Les changements par rapport à l'édition précédente sont les suivants: a) Tous les articles ont été renumérotés b) Le modèle de l'ISO 67 a été ajouté à cette norme comme Annexe A c) Dans l'Article 8 : Résistance à la traction et allongement à la rupture La procédure modifiée indique vitesse du mouvement au lieu de limite de temps . La vitesse du mouvement pour le mica pur est différente de celle du mica renforcé et/ou imprégné. d) Dans l' Article 11: Rigidité La taille des éprouvettes a été revue. Certains termes ont été modifiés car cette norme couvre des matériaux utilisés pour d'autres fonctions comme les revêtements en laine de verre ou les matériaux triplex. Révision des termes sens de fafrication et sens perpendiculaire . (Ils étaient incorrects dans la deuxième édition (1987).) e) Article 13: Compressibilité élastique et compressibilité plastique La tolérances dans la mesure de la hauteur de la pile a été changée pour à 0,01 mm près Le temps de changement de la pression dans le mode opératoire a été changé en 1 min. f) Article 16: Rigidité diélectrique Insertion de l'Amendement 1 (1984) à la deuxième édition (1987). Modifications en relation avec la dernière édition de la EN 60243-1. g) Article 19: Recherche des défauts et des particules conductrices Révision du paragraphe.

This European Standard was approved by CENELEC on 2004-09-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech
