We support you throughout the entire certification process

Pre-Certification (Design Stage)

Risk protection in the planning phase: TÜV Rheinland and designated external consultants review whether the plant is certifiable.

Initial Certification

When the plant is commissioned, TÜV Rheinland conducts an on-site audit. Upon a positive audit result, we issue the CertifHy EU RFNBO certificate.

Ex-Post Certification

Six months later, a re-certification is conducted based on actual operating data.

Regular Re-Certification

Re-certification is required at least annually to maintain certification validity and to remain in regulatory compliance.
