ISO 9001 vs ISO 13485
QMS for Medical Devices Explained

ISO 13485 is the medical-device sector QMS. Unlike AS9100 or IATF, ISO 13485 deliberately departs from ISO 9001’s 2015 revision, retaining the older Annex L structure to stay aligned with regulatory expectations (FDA, MDR, MDSAP).

Who Each Standard Is For

ISO 9001 is for…

Any organisation seeking a baseline QMS.

ISO 13485 is for…

Medical device manufacturers, contract manufacturers, sterilisation services, software-as-medical-device (SaMD) developers, and component suppliers in the medical supply chain.

Side-by-Side Comparison

All ten dimensions head-to-head:

AspectISO 9001ISO 13485
Industry scopeUniversalMedical devices only
StructureAnnex SL 10 clauses (2015 revision)Older 8-clause structure (intentionally)
Risk managementRisk-based thinkingISO 14971 device risk management mandatory
Process validationWhere output cannot be verifiedMandatory for any process affecting product
Document controlLighter (any controlled documents)Heavy — Device Master Record, DHR, design history file
Regulatory linkNo explicit regulatory linkAligned with FDA QSR, EU MDR, MDSAP
Post-market surveillanceNot requiredMandatory — vigilance, complaints, recalls
Sterile/implantNot addressedDedicated clauses for sterile and implantable devices
Software in devicesNot addressedAligned with IEC 62304 software lifecycle

When to Choose Which

Choose ISO 9001 when…

Choose ISO 9001 if you have no plans to manufacture, design, distribute or service medical devices.

Choose ISO 13485 when…

Choose ISO 13485 if you are anywhere in the medical-device value chain — it is required by virtually every regulator (UK MHRA, EU notified bodies, FDA via MDSAP, Health Canada).

Or hold both

You can hold both, but unlike IATF/AS9100 the structures differ — 13485 is NOT a superset of ISO 9001:2015. Many organisations hold both for the corporate (ISO 9001) and product (13485) sides.

Frequently Asked Questions

Why doesn’t ISO 13485 follow Annex SL?

Regulators (notably FDA) requested ISO retain the older structure to keep alignment with existing regulatory frameworks (21 CFR 820, EU MDR). ISO 13485:2016 deliberately did not adopt the Annex SL 10-clause format.

Is ISO 13485 a regulatory requirement?

Not directly — it’s voluntary — but it satisfies the QMS requirements of most medical-device regulators worldwide. MDSAP audits cover 13485 plus FDA, Health Canada, TGA, ANVISA, MHLW.

Does ISO 13485 cover medical software?

Yes — SaMD (Software as a Medical Device) products fall under 13485 and are also commonly aligned with IEC 62304.

How does ISO 14971 fit in?

ISO 14971 is the device risk-management standard explicitly referenced by 13485. You cannot pass 13485 without an ISO 14971-compliant risk file per product.
