STANAG 7158
STANAG 7158 electromagnetic interference test methods for aerospace ground equipment
Manufacturers and buyers of aircraft ground support equipment who must show it meets electromagnetic interference requirements before it operates near or connects to an aircraft.
STANAG 7158 is the NATO agreement on electromagnetic interference test methods for aerospace ground equipment. NATO has not released it publicly; this page describes it from the Czech defence standard that introduces it alongside AECTP-500.

NATO has not released this STANAG publicly. It is NATO UNCLASSIFIED, and organisations that need it obtain it through their national standardization authority.
What it is
STANAG 7158 is the NATO Standardization Agreement on electromagnetic interference, test methods for aerospace ground equipment. Edition 1, promulgated on 2 February 2009, under committee MC, MCASB, AE.
NATO has not released STANAG 7158 publicly. This page describes it from a public national implementation, the Czech defence standard ČOS 051627 (5th edition, amendment 2, 2025), which states it introduces AECTP-500 edition E (STANAG 4370 edition 7) together with STANAG 7158 edition 1 into Czech use, as one combined standard. A national implementation can add national requirements and reservations, so treat what follows as the Czech implementation's content, not as NATO's own text. A second Czech standard, ČOS 599903 on verifying the electromagnetic immunity of aircraft, also implemented STANAG 7158 alongside STANAG 3614, STANAG 3516 and STANAG 7116, but the national index records it as cancelled without replacement.
What the combined Czech standard covers
ČOS 051627 sets out to establish uniform test procedures and methods for determining the susceptibility of military materiel to the electrical and electromagnetic environment and its electromagnetic emissions. It contains generic test procedures and methods from which a specific test plan must be assembled for each application, and its structure follows the allied publication AECTP-500 edition E. The standard organises its tests into ten categories, numbered 501 to 510, covering equipment and subsystems, personal and portable equipment, ground support equipment, platforms and systems by domain (air, sea and land), munitions, space, and miscellaneous tests.
How ground support equipment is classified
Category 503 sets out the minimum EMC test methods for evaluating ground support equipment across all three services (air, land and sea). Its stated aim is to improve international cooperation and standardisation between nations on regulating electromagnetic interference, both emissions and susceptibility, from ground support equipment. For aircraft ground support equipment (AGSE), the Czech implementation sets three importance categories that decide which tests apply: category E1 for equipment that is electrically connected to the aircraft or whose incorrect operation could endanger flight safety or the mission; category E2 for equipment that operates close to the aircraft, including inside a hardened aircraft shelter, without a direct electrical connection; and category E3 for equipment used away from the aircraft and the airfield apron. Ground forces' own support equipment is classified instead by its working distance from the nearest radio antenna, in four bands from under 2 metres to over 100 metres, because protecting nearby radio receivers from interference is the dominant concern for that equipment.
How we help
A supplier bound by STANAG 7158 through a contract holds the obtained text through its national authority. In ComplyTrain you record the requirements that apply to you as your own requirements, give each an owner, and keep the evidence that shows you meet them against each one.

Three partners, three Member States, one evidence base
The EDF consortium rule is usually quoted as three entities from three Member States. It has a second limb about control that the word independent quietly hides, and two exceptions that disapply it entirely.
