No. AS9100 is based on ISO 9001 and includes all ISO 9001 requirements, but an AS9100 certificate does not automatically mean you are separately certified to ISO 9001.
How AS9100 and ISO 9001 relate
AS9100 is an aerospace quality management standard that fully incorporates ISO 9001 and then adds aerospace-specific and regulatory requirements (for example, around configuration management, risk, product safety, and counterfeit parts).
Practically, this means:
- If you are conformant to AS9100, your quality management system is designed to meet ISO 9001 requirements plus additional aerospace clauses.
- If you are certified to AS9100, the audit criteria include ISO 9001 requirements, but the certificate itself may or may not list ISO 9001 as a separate certification.
Certification reality: it depends on the certificate
Whether your AS9100 certificate also counts as an ISO 9001 certificate depends on:
- How the certification body issues certificates. Some issue a combined “AS9100 including ISO 9001” certificate, others issue one certificate referencing AS9100 only.
- Contract and scope wording. Your contract with the certification body and your scope of certification determine what is listed on the formal certificate.
- Customer and regulatory expectations. Some customers explicitly require “ISO 9001 certification” in addition to or instead of AS9100 and will look for that language on the certificate itself.
Auditors and customers typically treat AS9100 as at least as stringent as ISO 9001, but from a documentation and purchasing perspective, they may still insist on seeing ISO 9001 named on the certificate or in the accreditation listing.
Implications for aerospace and regulated manufacturers
For plants operating under AS9100 in a brownfield environment with long-lived equipment and mixed systems (ERP, MES, QMS, PLM):
- Do not assume that an AS9100 certificate will satisfy a contract clause that explicitly calls for “ISO 9001 certification” without customer confirmation.
- Check the exact wording on the certificate and in the certification body’s online registry to see whether ISO 9001 is listed as a standard.
- Align internal documents (quality manual, quality plans, supplier requirements) so they clearly describe which standards you are certified to and which you simply use as a design basis.
- Supplier management: When you flow down requirements, be explicit: “AS9100 certified” and/or “ISO 9001 certified” rather than assuming one implies the other.
What to do if you need both names on the certificate
If customer or internal policy requires certificates listing both standards:
- Contact your certification body and request that the scope be updated or that a combined certificate (AS9100 including ISO 9001) be issued, if their accreditation allows.
- Confirm any additional audit or administrative steps they require to formally list ISO 9001 alongside AS9100.
- Manage this via change control and document updates so that quality plans, supplier manuals, and ERP/MES master data all reference the correct certification set.
Bottom line: AS9100 incorporates ISO 9001 requirements, but you should not represent yourself as ISO 9001 certified unless your certificate and the certification body’s listing explicitly state ISO 9001 in the scope.
