IEC 60641-2-ed.2.0

Annotation of standard text IEC 60641-2-ed.2.0 :

Applies to pressboard and presspaper for electrical purposes. The series does not apply to laminated material. This part specifies the test methods to be used in testing pressboard and presspaper for electrical purposes to meet the requirements prescribed in the specification sheets of Part 3. NOTE In this standard, reference is made in several places to ISO standards accompanied by a short description of the method used. It is to be understood that this short description is meant for identification purposes only and that all details should be taken from the ISO standard itself. The main changes with respect to the previous edition are listed below: The following test methods have been cancelled: - Flexibility - Conductivity of the organic extract - Contamination of liquid dielectrics The following test methods have been rewritten: - Compressibility - Conductivity of the aqueous extract - Cohesion between plies The following test method has introduced: - Determination of metallic particles with X-ray. Sapplique aux cartons comprimes et aux papiers comprimes a usages electriques. La serie ne traite pas des materiaux stratifies. Cette partie specifie les methodes dessais a utiliser lors des essais des cartons comprimes et des papiers comprimes a usages electriques afin de satisfaire aux exigences prescrites dans les feuilles de specifications de la Partie 3. NOTE A plusieurs reprises, la presente norme se refere aux normes ISO et donne un bref apercu de la methode utilisee. Il est entendu que cet apercu ne remplit dautre objet que celui de servir de point de repere et que seule la norme ISO proprement dite contient tous les details necessaires. Les principaux changements par rapport a ledition precedente sont repertories ci-dessus: Les methodes dessai suivantes ont ete annulees: - Flexibilite - Conductivite de lextrait organique - Contamination des dielectriques liquides Les methodes dessai suivantes ont ete reformulees: - Compressibilite - Conductivite de lextrait aqueux - Cohesion entre couches La methode dessai suivante a ete introduite: - Determination de particules metalliques aux rayons X.
