It depends on where the machine is installed, not on the manufacturer. A European airport asks for CE marking under the Machinery and EMC directives; a US site asks for FDA listing and FCC compliance; a Chinese site asks for Ministry of Public Security testing. ISO 9001 is not a product certificate at all — it certifies the factory's quality system. Buyers should ask for the certificate and the test report, because a certificate without a report tells you nothing about the model in front of you.
Ask for three things: the certificate number with the issuing body, the test report behind it, and the model list on the certificate. Then check the issuing body in the relevant register — an EU notified body has a four-digit number that can be looked up in NANDO, and an ISO certificate must name the certification body and the scope. Certificates that list no model, no standard and no issuing body should be treated as marketing material.
No. A CE certificate names the models and standards it covers. If your model is not listed, ask for an amendment or a new test — a certificate for a different tunnel size does not automatically cover yours.
No. Most security X-ray scanners are listed/registered rather than cleared through 510(k), which applies to medical devices with a predicate. Ask which route the manufacturer used and for the corresponding document.
Yes — request them with the quotation. A manufacturer that will not share the report for the exact model is telling you something.
Because it is the only third-party evidence that the factory has a documented, audited process — which is what you rely on for consistency across repeat orders.
