STANAG 4864
STANAG 4864 assessing munitions against extreme but credible threats
NATO nations ratifying and implementing STANAG 4864, and suppliers meeting AOP-4864 under a contract or tender that names it
STANAG 4864 is NATO's agreement bringing AOP-4864, Edition A, into force, committing ratifying nations to harmonise munitions testing against extreme but credible threats instead of duplicating effort.

What it is
STANAG 4864 is the NATO standardization agreement covering the policy and methods to assess the response of munitions to extreme but credible threats. It is the agreement layer, promulgated 22 June 2026, and it "does not supersede any document" - there is no earlier edition it replaces.
A STANAG is not the specification
A STANAG is the agreement by which NATO nations commit to implement a standard, not the technical specification itself. STANAG 4864's own text is short and administrative: an aim, two interoperability requirements, and the ratification and reporting machinery. The technical content - what "extreme but credible threats" means in practice and how a munition's response to them is assessed - lives in a separate publication, AOP-4864, Edition A, which participating nations "agree to implement the following standard" by naming. Anyone actually running that assessment work needs AOP-4864's own text, not this cover agreement.
What the agreement is for
The stated aim is "to respond to the following interoperability requirements". The first is to define the policy for assessing munitions against extreme but credible threats, built around test work from disciplines the STANAG names as IM and HC that "can be harmonized" rather than repeated separately by each nation. The second is to cut the time and cost of that duplicated effort and build a more complete body of evidence for munition safety decisions. Both are reasons the agreement exists, not a description of the tests themselves - the methods and thresholds are AOP-4864's content, not this STANAG's.
Under "Other Related Documents", the STANAG also names STANAG 4123 (which brings AASTP-03, on hazard classification of military ammunition and explosives, into force) and STANAG 4439 (which brings AOP-39, the policy for introduction and assessment of insensitive munitions, into force). Both sit alongside AOP-4864 as test disciplines this agreement draws on.
Who it binds, and how
STANAG 4864 binds nations, not suppliers. It is effective "upon receipt for use by the participating nations and NATO bodies", and it becomes binding on a given nation through ratification, which NATO records in the NATO Standardization Documents Database (NSDD). Implementation is a separate, further step: the STANAG is considered implemented "when a nation has issued the necessary orders and instructions, putting the contents of this agreement into effect" - a domestic administrative act. Allied nations and NATO bodies are then obliged to report implementation details through NATO's electronic reporting tool; partner nations are only invited to do the same. The agreement names no NATO-wide effective date of its own - its "NATO Effective Date (NED)" field reads "Not applicable" - so there is no blanket start date to point to. A supplier meets STANAG 4864, or AOP-4864 underneath it, only where a contract or tender says so.
How it's evaluated
STANAG 4864 describes no certification scheme and no audit of its own. What it describes is nations reporting their ratification and implementation status for the record - "National responses are recorded in the NATO Standardization Documents Database (NSDD)" - which is government-to-NATO reporting, not a third party auditing a supplier or a product. Whatever assessment actually happens against AOP-4864's own methods, and whatever a contract's quality clause layers on top of it, is a matter for that publication and the contract, not something this STANAG describes.
Standards it references
STANAG 4864 covers AOP-4864, the publication that carries the actual assessment policy and methods. Its "Other Related Documents" also name STANAG 4123, which brings AASTP-03 (hazard classification of military ammunition and explosives) into force, and STANAG 4439, which brings AOP-39 (the policy for introduction and assessment of insensitive munitions) into force. Reviews of STANAG 4864 itself run under AAP-03.
How we help
STANAG 4864 is an agreement between nations, not a checklist an organisation implements directly. The practical work sits in AOP-4864, the publication this agreement brings into force, and in the related STANAGs it names alongside it. ComplyTrain does not run munitions testing or the hazard-classification and insensitive-munitions assessment work those publications describe - that is done in a test house or a design authority's own facility, not in software.
What ComplyTrain does for that kind of work generally is give a defence supplier one auditable place to hold the procedures for deciding which test evidence applies to a given programme, the training records for the people who own that work, and a controlled place to keep contract-specific requirements alongside the publications a tender names - the evidence trail a customer's quality representative or a government surveillance visit will ask to see.
Which STANAGs and Allied Publications actually apply to a given munitions programme is set by the contract and the customer's quality clause, not by us. Browse the explorer to see what sits alongside STANAG 4864 and AOP-4864, and talk to us about the evidence trail once you know which ones are in your contract.

Questions
Is STANAG 4864 mandatory?
Only where a nation has ratified and implemented it, and it reaches a supplier only where a contract or tender invokes it. The agreement's own "NATO Effective Date (NED)" field reads "Not applicable", so there is no blanket start date to point to.
What is the difference between STANAG 4864 and AOP-4864?
STANAG 4864 is the NATO ratification agreement; AOP-4864, Edition A is the publication that actually sets out the policy and methods for assessing a munition's response to extreme but credible threats. Ratifying STANAG 4864 is how a nation commits to implement AOP-4864.
Can a company be certified to STANAG 4864?
No. STANAG 4864 describes nations ratifying and reporting implementation to NATO, recorded in the NATO Standardization Documents Database. It describes no certification or audit scheme for a supplier or a product.
Does STANAG 4864 replace an earlier agreement?
No. The document states plainly that "this STANAG does not supersede any document."
How does STANAG 4864 relate to STANAG 4123 and STANAG 4439?
STANAG 4864 names both as related documents: STANAG 4123 brings AASTP-03 (hazard classification of military ammunition and explosives) into force, and STANAG 4439 brings AOP-39 (the policy for insensitive munitions) into force. Both cover test disciplines that STANAG 4864's own harmonization aim draws on.
