STANAG 3457
NATO nations and NATO bodies implementing aircraft ground electrical power interoperability requirements
STANAG 3457 is NATO's agreement committing member nations to implement ISO 461 and ISO 6858, the civil standards covering aircraft ground electrical power connectors and general requirements.
STANAG 3457 is the NATO standardization agreement that gives force to three ISO standards covering ground electrical power supplies for aircraft: ISO 461-1 and ISO 461-2, which set the design, performance, test and dimensional requirements for the connector used for aircraft ground electrical servicing, and ISO 6858, which sets general requirements for aircraft ground support electrical supplies. A STANAG is not itself a technical specification: it is the agreement by which NATO nations commit to implement one, and here the specification it covers is not a NATO Allied Publication but three civil ISO standards, obtained from ISO and national standards bodies on their own terms rather than from NATO. NATO's own STANAG document is free from the NATO Standardization Document Database; ISO 461-1, ISO 461-2 and ISO 6858 are sold by ISO and by national standards bodies, not by NATO and not by us.
This STANAG responds to an interoperability requirement stated plainly in the document: standardized provisions and procedures "for cross-servicing of aircraft ground electrical power supplies." Read plainly, that means the agreement exists so that ground power equipment fielded by one NATO nation can service an aircraft belonging to another, not so that a single national design is imposed on everyone.
This is Edition 8, dated 9 February 2023. It supersedes STANAG 3457, Edition 7, dated 24 March 2014.
The mechanism that matters here: a STANAG binds a nation, not a supplier. Nations "are invited to examine their ratification of the STANAG and, if they have not already done so, advise the NSO of their intention regarding its ratification and implementation," and the national response is recorded in the NATO Standardization Document Database (NSDD). Once ratified, the agreement "is effective upon receipt for use by the participating nations and NATO bodies." A manufacturer of ground power equipment, or an aircraft type, meets ISO 461 or ISO 6858 only where a contract or a tender brings one of them in by name, not because this STANAG exists on its own.
Participating nations "must ensure that aircraft and ground power supply equipment being used are equipped with connectors for aircraft electrical servicing power compatible to ISO 461," and that "ground electrical power supply equipment being used must meet ISO 6858 general requirements." Neither figure is restated here: the connector's design, performance and dimensional requirements live in ISO 461-1 and ISO 461-2, and the general requirements for the supply itself live in ISO 6858.
Implementation reaches two further STANAGs, and the document is specific about the language it uses for each. Electrical grounding and bonding between aircraft and ground equipment "shall be in accordance with the methods and procedures of STANAG 3632," and electrical hazards on the flight line "must be considered in accordance with STANAG 7009." Both read as binding commitments within the implementation clause. AAEP-02 and AEP-24 appear in the same list of other related documents, but the text available to us says nothing further about either beyond naming them.
Allies and NATO bodies "shall provide implementation details through the electronic reporting tool (e-Reporting)," and the STANAG itself "is to be reviewed in accordance with AAP-03," with the result recorded in the NSDD.
No certification exists here, and the document names none. What it describes is a national ratification, implementation and review cycle run through NATO's own machinery, not an audit against this STANAG as such. Whatever assessment a manufacturer of ground power equipment or an aircraft type actually faces runs through the customer's own airworthiness or procurement quality process, wherever that process invokes ISO 461 or ISO 6858 by name.
STANAG 3457 and the ISO standards it points to describe an interoperability and interface requirement, not a management system: whether a connector mates correctly and a power supply meets ISO 6858's general requirements is a matter of engineering and test, not software. What that leaves to evidence is the paperwork around it: procedures that correctly reference ISO 461, ISO 6858, STANAG 3632 and STANAG 7009 where a contract calls for them, records that show ground power equipment or an aircraft type was checked against whichever of those standards is actually in force, and the trail an internal or customer audit asks for afterwards.
ComplyTrain holds that evidence as a modern, auditable system: version-controlled procedures, records tied to named individuals, equipment and dates, and corrective actions when a gap turns up, all searchable when a customer's quality clause asks for it. It does not test a connector, certify a ground power unit, or decide how a nation implements the agreement, and it does not replace the ratification and reporting nations carry out themselves through the NSDD.
The applicable tier here, and whatever else it comes with, is set by the contract and the customer's quality clause. If you are working out what sits alongside STANAG 3457, the standards explorer covers the related NATO and ISO documents, and we are glad to talk through what that means in practice.

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.
Not in general. It binds a nation once that nation ratifies it, and it reaches a manufacturer or supplier through a contract or a tender that names ISO 461, ISO 6858 or this STANAG, not by existing on its own. Whether it applies to a given programme is set by the tasking or contract in front of you.
STANAG 3457 is NATO's agreement to implement ISO 461 and ISO 6858 for aircraft ground electrical power: the letter of promulgation, the ratification record, and the implementation and review machinery. ISO 461 and ISO 6858 are the civil standards themselves, obtained from ISO and national standards bodies, and they carry the actual connector and general requirements.
No. The implementation clause invokes STANAG 3632 for aircraft and ground equipment grounding and bonding separately, alongside STANAG 7009 for electrical hazards on the flight line.
Edition 8, dated 9 February 2023. It supersedes STANAG 3457, Edition 7, dated 24 March 2014.
No. There is no accredited certification for STANAG 3457, ISO 461 or ISO 6858 to hold on a supplier's behalf, and ComplyTrain does not claim one. What we support is the evidence trail around procedures and records for the standards a contract actually invokes, at an informational level.
