Manufacturers must design their products to meet the precise geometric ratios outlined in the standard to achieve certification.
Once the SPS class is locked in, IEC 60815-2 provides a baseline USCD value (expressed in mm/kV). The creepage distance is the shortest path along the surface of the insulating material between two conductive parts.
The standard's main technical objective is to help engineers determine the necessary for an insulator. The creepage distance is the shortest path along the insulator's external surface between the live and grounded ends. iec 60815-2 pdf
