How about the class defination of electrical insulation materials?
The use life of electrical insulation products is affected by many factors, the temperature usually is the aging of insulation materials and dominant factor. Therefore, there is a practical, by the world recognized heat-resistant classification method, which is the electrical insulation of the heat resistance was divided into a number of heat-resistant class. According to China standard of GB 11021-89 (IEC 85), and all heat levels and the corresponding temperature values are as following:

Brief of Electricl Insulatin Material
What is insulation material? Today we are talking only electrical insulation Material.
In China,according to the defination of China GB standard(GB 2900.5), insulation material is material which used to keeping the electrical parts insulative from the power. That means the material is used to prevent electric current pass the electrical parts. Usually this kind of material has very high electrcial resistance about 10^6~10^19Ω•m. For example, the insulation material can prevent the loops on the rotor from the slot that it can make the motor working safely.
