QUESTION

Does an ISO 9001 logo on a company website establish that the company currently holds ISO 9001 certification?

CONTRADICTED as a general rule. A self-published badge is not an issuer record. ISO certification is issued by certification bodies and is date- and scope-bounded. This demonstration does not evaluate any named real company.

Procurement still needs a certificate number, issuer, scope, and expiry checked at the issuer or an accredited register. No company is named. No customer case study is implied.

EVIDENCE REQUIREMENTS

• R1 · Primary issuer record · ADDRESSED

  Certificates must be checked at the issuer, not a screenshot. Addressed in this demonstration from cited public records.

• R2 · Scope and date of the claim · ADDRESSED

  Expired or narrow-scope certificates are often overstated. Addressed in this demonstration from cited public records.

• R3 · Independent registry check · ADDRESSED

  Second source in a different independence group. Addressed in this demonstration from cited public records.

• R4 · What remains unknown · ADDRESSED

  Missing fields stay missing. Addressed in this demonstration from cited public records.

PRIMARY EVIDENCE CARDS

INDEPENDENT CORROBORATION

• Independent support branches: 0
• Independent contradict branches: 1
• Engine: At least one independent contradicting branch; no independent support remains.

LINEAGE

• L-iso · iso.org

CONFLICTING

• Self-published badges conflict with the issuer-check requirement.

MISSING EVIDENCE

• Named certificate number + issuer registry hit

  Why: Only an issuer record can support a specific company claim.

  How to obtain: Ask the supplier for cert number; check the certification body.

WHAT WOULD CHANGE THIS FINDING

• This general finding would change if ISO itself issued website badges as certificates — it does not.
• A specific company finding would require an issuer registry check.

CHALLENGES

• NONE_FILED: Demonstration compile. Challenge this finding is open.

TIMELINE

• 2026-09-02T00:00:00.000Z — Demonstration report compiled from cited public records.
• 2026-09-02T00:00:00.000Z — evaluateCase run on recorded facts. No silent rewrite.

LIMITATIONS

• DEMONSTRATION of method. Not a statement about any real supplier.
• Not a legal opinion.

METHODOLOGY

Duplios Proof of Evidence Standard v0.1 (Duplios methodology — not an ISO, accredited, or industry-consensus standard). A question is decomposed into evidence requirements. Sources are recorded with independence groups and lineage. Copies that share an origin are one confirmation. Contradiction is searched, not assumed absent. AI output, detector scores, missing EXIF, and missing C2PA credentials are evidence or absences — not truth. evaluateCase returns SUPPORTED, CONTRADICTED, INSUFFICIENT_EVIDENCE, or HUMAN_REVIEW_REQUIRED. UNKNOWN stays UNKNOWN. A report hash identifies the bytes of this version; it does not prove the finding is true.
