Classification - Surface insulations of electrical steel sheet, strip and laminations
Organization:
JSA - Japanese Standards Association
Year: 2014
Abstract: This Standard establishes a classification of surface insulations for electrical steel sheet, strip and laminations according to their general composition, relative insulating ability and function.
These surface insulations are either oxide layers or applied coatings.
The purpose of this classification is to create a nomenclature for the various types of surface insulations and to assist users of surface insulations by providing general information about the chemical nature and use of the surface insulations.
It is not the intent of this classification to specify insulation requirements in terms of specific values of surface insulation resistance. Such requirements are agreed between the purchaser and the manufacturer, where applicable.
The classification is used in conjunction with the various specifications for cold rolled electrical steels (see clause 2).
NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows:
IEC 60404-1-1: 2004 Magnetic materials-Part 1-1: ClassificationSurface insulations of electrical steel sheet, strip and laminations (IDT)
The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ IEC Guide 21-1.
