What is the difference between a test report and a certification?

A test report confirms a measurement result at a point in time on a submitted sample. A certification additionally assesses conformity with a defined programme, monitors continued compliance and governs which claim may be made at all.

The two levels interlock and are accredited differently:

Accredited testing laboratory (ISO/IEC 17025)Certification body (ISO/IEC 17065)
Confirms a measurement resultAssesses conformity with a programme
Relates to the sample submittedRelates to the product within a defined scope
A snapshot in timeOngoing surveillance, recertification
No statement on the permissible claimGoverns the permissible claim and its labelling
Not publicly verifiablePublicly verifiable via certificate and database

For internal technical documentation a test report can be sufficient. As soon as it becomes a claim towards customers, retail or consumers, it generally is not. In the flustix programmes, laboratories accredited to ISO/IEC 17025 carry out the testing; the conformity assessment is made independently to ISO/IEC 17065.
