STANAG 4239: Electrostatic Discharge, Munitions Test Procedures

Scope of STANAG 4239 ESD Standard

The Military Agency for Standardization (MAS) released this Standardization Agreement (STANAG 4239) outlining the electrostatic discharge test procedures in determining the safety and suitability for service of munitions containing electro explosive devices (EEDS) and associated electrical/electronic systems and subsystems, in the electrostatic environmental conditions specificed in STANAG 4235 for NATO forces. Guidance on electrostatic discharge (ESD) hazard assessment and testing is provided in AOP-24 document.
