STANAG 3209
Manufacturers of tyre valve couplings and aircraft ground-servicing organisations working to a contract that invokes STANAG 3209 or the AASSEP-4 standard it covers
STANAG 3209 is NATO's ratification agreement committing member nations to implement AASSEP-4 Edition A, the standard for tyre valve couplings used in aircraft cross-servicing.
STANAG 3209 is the NATO Standardization Agreement covering tyre valve couplings, under which participating nations agree to implement AASSEP-4, Edition A. This is Edition 6, promulgated 21 October 2014, superseding Edition 5 of the same STANAG.
A STANAG is the agreement by which NATO nations commit to implement a standard, not the technical specification itself. STANAG 3209's own text is short and administrative: an aim, one interoperability requirement, and the ratification, implementation and review machinery. The coupling requirements themselves are not written here; the STANAG names the publication that carries them, "AASSEP-4, Edition A", which participating nations "agree to implement". Anyone actually designing, manufacturing or checking a tyre valve coupling against those requirements needs AASSEP-4's own text, not this cover agreement.
The stated aim is interoperability. The single interoperability requirement is "to standardize tyre valve couplings to facilitate cross-servicing of aircraft" - so that ground crews from one NATO nation can service the tyres of another nation's aircraft with common equipment. The document also lists three civil standards under "Other Related Documents": ISO 4570 (tyre valve threads), ISO 7295 (tyre valves for aircraft, interchangeability dimensions), and ISO 20562 (tyre valves, ISO core chambers).
STANAG 3209 binds nations, not suppliers. It is "effective upon receipt and ready to be used by the implementing nations and NATO bodies", and it becomes binding on a given nation through ratification, which NATO records in the NATO Standardization Document Database (NSDD). Partner nations are not asked to ratify in the same way; they "are invited to adopt this STANAG". Implementation is a further, separate step: the STANAG "is considered implemented when the provisions specified therein have been included in the national documentation concerned with reference to STANAG 3209". Nations then report that implementation using a NATO reporting form, and partner nations report adoption on a separate form. A supplier meets STANAG 3209, or the AASSEP-4 requirements it covers, only where a contract or a nation's own procurement documentation says so - the document itself sets no obligation reaching a supplier directly, and prints no NATO-wide effective date of its own beyond "effective upon receipt".
STANAG 3209 describes no certification scheme and no audit. What it describes is nations reporting their ratification and implementation status to NATO for the record; nobody is "STANAG 3209 certified", and the document never uses that language. Where a manufacturer's tyre valve coupling does get checked against AASSEP-4's requirements, the assessor and the evidence required are set by the contract's own quality clause, not by this STANAG.
STANAG 3209 covers AASSEP-04, the Allied publication that carries the actual coupling requirements. Nations report their implementation of this STANAG using forms carried in AAP-03, which informs the reporting mechanism rather than the technical content. Its "Other Related Documents" also name three ISO standards, ISO 4570, ISO 7295 and ISO 20562, which sit outside our catalogue.
STANAG 3209 and the AASSEP-4 coupling requirements it covers are followed in component manufacture and aircraft ground servicing, not in a compliance platform: a manufacturer builds the valve coupling to AASSEP-4's requirements, and a ground-servicing organisation trains its people and holds the records that show cross-servicing was carried out against the applicable requirement.
What ComplyTrain does for that kind of work in general is give a defence supplier one auditable place to hold the relevant procedures, the training records for the people doing that work, and the evidence trail - non-conformances, corrective actions, document control - that a customer's quality representative or a government surveillance visit will ask to see.
ComplyTrain does not manufacture a tyre valve coupling, inspect one, or determine whether a coupling meets AASSEP-4's requirements. That is mechanical engineering and quality-inspection work, carried out against the publication itself and the contract's own technical requirements.
Which STANAGs and Allied Publications actually apply to a given programme is set by the contract and the customer's quality clause, not by us. Browse the explorer to see what sits alongside STANAG 3209 and AASSEP-4, and talk to us about the evidence trail once you know which ones are in your contract.

Thank you. Your list is on its way to your inbox, and we will come back to you on what working with these standards in ComplyTrain involves, usually within one business day.
Only where a nation has ratified and implemented it, and it reaches a supplier only where a contract or procurement document invokes it. The STANAG itself sets no date that applies to everyone; each nation reports its own ratification and implementation timing to NATO.
STANAG 3209 is the NATO ratification agreement; AASSEP-4, Edition A is the publication that actually specifies the tyre valve coupling requirements. Ratifying STANAG 3209 is how a nation commits to implement AASSEP-4.
No. STANAG 3209 describes nations ratifying and reporting implementation to NATO, recorded in the NATO Standardization Document Database. It describes no certification or audit scheme for a supplier or a product.
The document states that this edition supersedes "STANAG 3209, Edition/Édition 5, TYRE VALVE COUPLINGS", but it does not itself describe what changed between the two editions.
No. STANAG 3209 is the ratification cover. The actual coupling requirements are specified in AASSEP-4, Edition A, the publication this STANAG names and that participating nations commit to implement.
One system for the whole compliance programme. Start with the module you need most.
Collect information the same way every time, and decide in advance what happens next.
Know whether your controls are operating, not just whether a policy says they exist.
Turn the compliance work you already know about into a plan with owners, dependencies and dates.
Know what you can offer, and hold the evidence behind every configuration you offer it in.
Eight built-in reports across every module, scheduled, delivered, and filed where the evidence lives.
The sector news that matters to your organisation - read and rated by AI, and delivered as a scheduled digest in your own language.
AI reads the tender pack and pulls out the requirements, deadlines and rules - then helps you draft the response from your own approved content, with you reviewing every step.
One current register of the suppliers and partners you depend on - each risk-assessed, re-assessing itself on schedule, and wired straight into your risk register.
See every requirement you face - across every standard, plus your own contracts and policies - traced to the documents, evidence and processes that satisfy it.
Identify, score, treat and review your risks in one place - with AI to help anyone run a proper assessment, and a defensible trail behind every decision.
Assign training, prove it was understood, and hold the competence records an auditor asks for.
Draft compliance documents with AI, keep every version under control, and export them beautifully branded - all in one place.
Audits, corrective actions, processes and approvals in one quality system, organised around ISO 9001.
Medical device manufacturers operate under more regulatory pressure than almost any other sector outside pharmaceuticals. The rules govern how you design a device, how you make it, how you track it after it ships, and how you respond when something goes wrong.
