Testing and audits in TCO Certified are carried out by independent, accredited verification organizations.
These organizations are approved by TCO Development and specialize in areas such as IT products, environmental responsibility, and social sustainability. All test facilities are accredited according to ISO/IEC 17025, ensuring that assessments are carried out using reliable and internationally recognized methods.
Verification includes product testing, factory audits, and review of documentation. Products are tested to ensure they meet technical and environmental criteria, while factories are audited to assess working conditions and environmental performance.
Verification is conducted both before certification and throughout the certificate’s validity period. Independent experts also carry out follow-up activities such as spot checks and re-testing to ensure that compliance is maintained over time.
By using independent verification organizations, TCO Certified ensures that all assessments are impartial and based on evidence, not on claims made by IT brands.
