Harmonized standards:

Harmonized standards are a specific category of European standards developed by one European Standardization Organization, following a request submitted by the European Commission known as a "mandate". Almost a fifth of all European standards are developed following a request (mandate) for standardization from the European Commission.

You can use harmonized standards to prove that your products or services comply with the technical requirements of the relevant EU legislation.
