Product Certification Services
Product certification is third-party attestation that a product, process, or service conforms to specified requirements. This domain tests the certification-body view of that work: how applications are reviewed, how evidence is gathered, who decides, and how certificates and marks are controlled. Expect questions that separate certification from testing and that probe surveillance and scope control.
The certification sequence under ISO/IEC 17065
- Application review: the body confirms the requested product, standard, and scheme sit within its competence and accreditation/approval.
- Evaluation: sampling, testing, inspection, and assessment of production or service delivery, as the scheme requires.
- Review and decision: an authorized decision-maker, not the evaluator, determines certification. Test reports are inputs, not decisions.
- Issue and maintain: certificates carry a defined scope and validity period; surveillance and recertification keep them valid.
Scheme design and marks
ISO/IEC 17067 describes scheme types 1–6, which combine sample testing, factory assessment, and surveillance in different mixes. The scheme rules-not customer preference-set sampling, surveillance intervals, and mark conditions. ISO/IEC 17030 covers third-party marks: use is permitted only for products within the certified scope.
Impartiality and scope control
The certification body must not be the manufacturer or hold a financial interest in the outcome, and personnel must be free of commercial pressure. The scope statement names product, standard, and production site. New variants or new manufacturing sites require evaluation before the certificate is extended.
Worked example
A luminaire manufacturer holds a certificate covering one product family made at Site A and asks to add a larger model made at Site B. The evaluator tests samples and assesses Site B, but the certificate is not amended until review and decision are complete and a revised scope is issued. A passing test report from an ISO/IEC 17025 laboratory does not itself extend the certificate; it is only evaluation evidence.
Traps that cost marks
- Treating a laboratory test report as equivalent to a product certificate.
- Assuming laboratory accreditation (ISO/IEC 17025) is product certification (ISO/IEC 17065).
- Allowing the certification mark on variants or sites outside the scope.
- Skipping surveillance because no complaint was received.
- Confusing the applicant with the certificate holder after a transfer.
