A certification logo on a presentation is not enough to explain the claim. Read the certificate and verify who issued it, what it covers and whether it remains valid.
ISO develops standards but does not itself perform certification or issue certificates. ISO — Certification.
Follow the actual claim
Identify the standard, organisation, site and activities named in the evidence. Distinguish a management-system claim from a product-specific claim. Do not expand either beyond the stated scope or imply that an unrelated product is covered.
Verify through the appropriate channel
Use the issuing or accreditation body's relevant verification route where applicable. If the information cannot be reconciled, keep the status unresolved. A high-resolution copy is not a substitute for checking identity and validity.
This approach helps a buyer evaluate what a supplier actually claims. No certification claim for PLUSHIP or Qunhe is made here, and no third-party certification mark is reproduced in the illustrations.
