Magnetic materials - Classification of surface insulations of electrical steel sheet, strip and laminations

This document 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 to be agreed between the purchaser and the steel producer, where applicable.
The classification is to be used in conjunction with the various specifications for cold rolled electrical steels (see the European Standards listed in Clause 2).

4 Classification of surface insulations of electrical steel, strip and laminations Table 1 specifies the classification of surface insulations of electrical steel sheet, strip and laminations. Table 1 — Classification of surface insulation of electrical steel, strip and laminations Insulation designation Insulation description – Characteristics – Typical application, limits of use EC-0 An oxide layer that is formed naturally on the steel surface during electrical steel manufacture. This oxide layer is thin, tightly adherent and provides sufficient surface insulation resistance for many types of small cores. This oxide layer will withstand normal stress relief annealing temperatures. If subjected to a user’s anneal after st
