AS9100 ISO 9001 Comparison: The Relationship Between the Two Standards
This AS9100 vs ISO 9001 guide explains the relationship between the aerospace quality standard and the general quality standard. AS9100 ISO 9001 comparison: AS9100 includes all ISO 9001 requirements plus approximately 100 aerospace-specific additions. ISO 9001 aerospace standard: for aerospace suppliers, AS9100 is the required standard — but understanding ISO 9001 is essential because AS9100 is built on it.
AS9100 and ISO 9001 are not competing standards — they are related standards, with AS9100 built directly on top of ISO 9001. Every requirement in ISO 9001 is also a requirement in AS9100. AS9100 adds approximately 100 additional aerospace-specific requirements on top of the ISO 9001 foundation.
Understanding this relationship is essential for aerospace organizations navigating the ISO 9001:2026 revision. When ISO 9001 changes, AS9100 must eventually change too — and aerospace organizations certified to AS9100 need to understand how the 2026 revision affects their certification.
Key Insight
Key Fact:: AS9100 Rev D (the current edition) is built on ISO 9001:2015. A future AS9100 Rev E will be built on ISO 9001:2026. Until AS9100 Rev E is published, aerospace organizations certified to AS9100 Rev D are not required to transition to ISO 9001:2026.

| First article inspection | Not required | Required |
| Key characteristics | Not required | Required |
| Counterfeit parts prevention | Not required | Required |
| Human factors | Not required | Required |
| Accreditation body | IAF members (UKAS, ANAB, etc.) | IAQG OASIS database |
| Certificate validity | 3 years | 3 years |
Who Needs ISO 9001 vs AS9100?
Stay Current
ISO 9001:2026 publishes September 16, 2026. Get weekly briefings.
ISO 9001:2026 is appropriate for:
- Any organization in any industry seeking a quality management system certification
- Organizations supplying to customers who require ISO 9001 certification
- Organizations in manufacturing, services, healthcare, construction, software, and other non-aerospace industries
AS9100 is required for:
- Organizations supplying to the aerospace, defense, or space industries
- Organizations that appear in the IAQG OASIS database as approved suppliers
- Organizations whose customers (Boeing, Airbus, Lockheed Martin, etc.) require AS9100 certification
If your organization supplies to both aerospace and non-aerospace customers, you may need both certifications — or AS9100 alone, since AS9100 includes all ISO 9001 requirements.
How ISO 9001:2026 Affects AS9100 Organizations
AS9100 Rev D is based on ISO 9001:2015. When ISO 9001:2026 is published on September 16, 2026, the International Aerospace Quality Group (IAQG) will begin work on AS9100 Rev E, which will be based on ISO 9001:2026.
What this means for AS9100 certified organizations:
- No immediate action required. AS9100 Rev D remains the current and valid aerospace quality standard. Publication of ISO 9001:2026 does not invalidate AS9100 Rev D certificates.
- AS9100 Rev E is coming. The IAQG will develop AS9100 Rev E incorporating ISO 9001:2026 requirements plus updated aerospace-specific additions. This process typically takes 2–4 years after the base ISO 9001 revision.
- Prepare for dual transition. Aerospace organizations will eventually need to transition to AS9100 Rev E. Organizations that understand ISO 9001:2026 now will be better prepared for AS9100 Rev E when it arrives.
- New ISO 9001:2026 requirements will likely appear in AS9100 Rev E. The quality culture, ethical behaviour, and opportunities management requirements from ISO 9001:2026 will almost certainly be incorporated into AS9100 Rev E, potentially with aerospace-specific additions.
The Three New ISO 9001:2026 Requirements and Their Aerospace Implications
Quality culture and ethical behaviour (Clause 5.1.1): Aerospace organizations already operate under strict ethical requirements (counterfeit parts prevention, product safety reporting). The ISO 9001:2026 quality culture requirement aligns well with existing aerospace culture requirements and is unlikely to require significant additional work.
Opportunities management (Clause 6.1.3): AS9100 Rev D already has detailed risk management requirements. The opportunities management addition in ISO 9001:2026 fills a gap that aerospace organizations may already address through their operational risk management processes.
Change effectiveness monitoring (Clause 6.3): AS9100 Rev D has extensive configuration management and change control requirements. The ISO 9001:2026 change effectiveness monitoring requirement is less demanding than existing AS9100 change control requirements.
Frequently Asked Questions: AS9100 vs ISO 9001
What is the AS9100 ISO 9001 comparison summary?
AS9100 ISO 9001 comparison: AS9100 is the ISO 9001 aerospace standard with additional requirements for the aerospace, defense, and space industries. AS9100 vs ISO 9001: every ISO 9001 requirement is also in AS9100, but AS9100 adds configuration management, key characteristics, counterfeit parts prevention, and other aerospace-specific requirements.
Does AS9100 replace ISO 9001?
No. AS9100 includes all ISO 9001 requirements plus additional aerospace-specific requirements. An AS9100 certificate demonstrates compliance with both AS9100 and ISO 9001.
Can I use my AS9100 certificate as proof of ISO 9001 compliance?
In most cases, yes. AS9100 includes all ISO 9001 requirements, so an AS9100 certificate demonstrates ISO 9001 compliance. However, some customers may specifically require an ISO 9001 certificate — check with your customer.
When will AS9100 Rev E be published?
No official timeline has been announced. Based on historical precedent, AS9100 Rev E is likely 2–4 years after ISO 9001:2026 publication — approximately 2028–2030.
Do I need to transition to ISO 9001:2026 if I have AS9100?
Not immediately. AS9100 Rev D is based on ISO 9001:2015 and remains valid. You will need to transition to AS9100 Rev E (based on ISO 9001:2026) when it is published and the transition period begins.
What is the cost difference between ISO 9001 and AS9100 certification?
AS9100 audits typically cost 20–40% more than ISO 9001 audits due to the additional requirements and the specialized aerospace auditor expertise required. See our ISO 9001 certification cost guideISO 9001 certification cost guide/article/iso-9001-2026-certification-cost-guide for baseline cost data.
