NATO Electromagnetic Environmental Effects (E3) Standardisation
Time:
Monday, 01/Sept/2025:
9:00am - 10:30am
Location:Auditorium
497 seats, basement
Session Abstract
Successful NATO operations involve the military forces of many nations, and interoperability is essential for their success. This interoperability is underpinned by standardisation across all facets of the alliance, including technical standards covering electromagnetic environmental effects (E3).
Electromagnetic compatibility plays a key role in ensuring that military equipment, systems, and platforms are not degraded by detrimental electromagnetic environmental effects which may be encountered during service – often long periods of time and exposure to severe environments.
The NATO Allied Environmental Conditions and Tests Publications (AECTP) series define the operational environments in which NATO defence materiel must be designed to function, and provide detailed test requirements to ensure that equipment, systems and platforms can meet their performance requirements while operating in these environments.
This tutorial aims to give the audience an overview of the current NATO E3 standards, how they have evolved over time to the point at which we now find them, and how they are used by nations to successfully build interoperability within the alliance.
Presentations
9:00am - 9:22am
NATO E3 Standardisation - An Introduction
Hywel S, AJM v Bladel
NATO E3 Action Team
This presentation introduces NATO Standardisation as a concept, explaining how alliance standards related to E3 fit ‘hand in glove’ with both civilian standards and national military procedures. It gives an overview of the groups involved in NATO E3 standards and the key references, with a view to important future NATO E3 standard updates.
9:22am - 9:44am
NATO STANAG 4868, AECTP-250 (E3 Environments) and AECTP-500 (E3 Test & Verification Methods) Overview
Hywel S, Matt H, AJM v Bladel
NATO E3 Action Team
This presentation aims to give a detailed overview of NATO AECTP 250 and AECTP 500. AECTP 250 (Electrical and Electromagnetic Environmental Conditions) contains all of the E3 environments that NATO materiel is required to be assessed against. This includes wide ranging environments from ‘traditional’ EMC considerations to high powered RF directed energy sources. AECTP 500 (Electromagnetic Environmental Effects Tests and Verification) contains the test methods NATO nations use to assess robustness of systems against the environments given in AECTP-250.
9:44am - 10:06am
NATO Land Platform EMC Testing
AJM van Bladel
NATO E3 Action Team
One of the detailed test requirements of the AECTP 500 concerns the test and verification procedure for land platforms and systems. This tutorial presentation discusses the general requirements and measurement setups using examples of military vehicles.
10:06am - 10:28am

To ensure the performance of radio communication systems in military operations, the platform interference level needs to be regulated. To address this issue, there exits military electromagnetic compatibility (EMC) standards. In this work, the NATO emission standard NRE04S for platform interference is examined and compared to an alternative level. The analysis is performed for the frequency bands 30-88 MHz and 225-512 MHz with typical radio parameters of a military tactical radio system in different kinds of electromagnetic environments.
