INTRODUCTION
Replace the text in the fourth paragraph by the following:
IEC 85 deals with thermal evaluation of insulating materials and insulation systems used in
electrical equipment. In particular, the thermal classes of insulation systems used in rotating
machines such as A, E, B, F and H, as well as the temperatures usually associated with these
thermal classes, are established in IEC 85. In the past, materials for insulation systems were
often selected solely on the basis of thermal endurance of individual materials. However, the
second edition of IEC 85 recognizes that such selection may be used only for screening
materials prior to further functional evaluation of a new insulation system which is not service-
proven. This evaluation is linked with earlier service experience through the use of a service-
proven reference insulation system as the basis for comparative evaluation. Service
experience is the preferred basis for assessing the thermal endurance of an insulation system.
Replace the text in the ninth and tenth paragraphs by the following:
In the winding of an electrical machine, different factors of influence can be dominant in
different parts (e.g. turn insulation and end winding insulation). Therefore, different criteria may
be used to assess those parts of the insulation. It can also be appropriate to apply different
procedures of functional evaluation to these parts.
The large differences found in the rotating electrical machine windings, in terms of size, voltage
and operating conditions, necessitate the use of different procedures of functional evaluation to
evaluate various types of windings. These procedures can also be of different complexity, the
simplest being based on a single ageing mechanism (e.g. thermal or electrical). In the present
state of the art, only thermal and electrical endurance testing procedures can be specified in
some detail. Principles of mechanical, environmental and multifactor functional testing are
briefly described to provide a basis for provisions to be developed later where appropriate.
