Paul, the minimum creepage distance and clearance requirements will be shown in the EN or IEC standard applicable to the product for which the board will be used.
These requirements will not be unique to Denmark or to DEMKO. There will be references to other EN or IEC standards that allow reduced spacing, or require additional spacing bases upon the installation overvoltage category, the materials being used, what pollution may occur, and other characteristics of your application. You should research and understand all of this thoroughly beforehand. The best way to avoid an issue with the connector is to specify a connector that meets the applicable standard and has an approval from a CEE member lab.
