This part of IEC 60664, which is a technical report, serves as an application guide for technical committees and manufacturers specifying dimensioning requirements for products in accordance with the IEC 60664 series. The significant items for consideration are as follows: nominal system voltage(s) or rated insulation voltage(s); overvoltage category of the products (OV cat.); any type of overvoltages; frequency of the voltage; characteristics of the solid insulating material; pollution degree and humidity levels.
