How are EASA approved components released to service following component maintenance activities?

Components are released by the authorized person who signs a Form 1 to release the component as a serviceable component.

Are other checks, tests or inspections considered as a Certificate of Release to Service (CRS)?

Exactly in the same way that the various elements of a base maintenance check contribute to the overall preparation of the completed work package which enables the base maintenance check to be signed by a C certifier, A Component CRS is certified by a person who has the knowledge back ground, experience, and competence to validate that all work has been performed to prepare the component for service.
