is the NATO Standardization Agreement that sets the testing requirements for Safety, Arming, and Functioning (SAF) Systems in munitions. Primary Objective

STANAG 4157 defines standardized safety and reliability test requirements for munition fuzing systems to ensure consistent performance and handling across NATO forces. It establishes protocols for environmental testing—including shock and temperature—to guarantee both safety during transport and reliable operation at the target. Official copies of the STANAG 4157 standard can be accessed through the NATO Standardization Office

As standards evolve, older editions become outdated and are formally superseded. For example, the national adoption of STANAG 4157 by Ukraine as was noted as cancelled ("cтатус: не діє") as of January 1, 2022, in favor of a newer version or a different national standard. This highlights the importance of always using the most current edition of a standard for compliance, procurement, or system design. While an older edition can be a valuable historical reference, it should not be used as the basis for new safety assessments.

STANAG 4157 applies broadly to what NATO defines as SAF Systems, a category that includes: stanag 4157 pdf

| STANAG | Title | Relationship | |--------|-------|--------------| | STANAG 4187 | Fuzing Systems – Safety Design Requirements | Establishes design requirements for SAF systems; STANAG 4157 tests those designs | | STANAG 4170 | Qualification of Explosive Materials | Addresses explosive material qualification requirements | | STANAG 4363 | Initiation Systems: Testing for Assessment of Detonating Explosive Components | Complements STANAG 4157 with specialized initiation system tests | | STANAG 4493 | Tank Ammunition | References STANAG 4157 for SAF system testing | | STANAG 4518 | Demilitarization and Disposal of Munitions | Principles for end‑of‑life munitions management |

Note that concerns “Maintenance and Test of Ammunition in Service” (shelf life, surveillance testing), not initial qualification. Do not confuse the two, though both are relevant to ammunition lifecycle.

Requires nations to document all design reviews and test results for new fuzing systems. Official copies of the STANAG 4157 standard can

Here is the most critical part of this article. If you need the authentic, complete, and legally authorized , you cannot find it on random file-sharing websites. Those copies are often outdated, incomplete, watermarked as "draft," or illegally obtained—which can lead to contractual or legal issues if used in official projects.

Defines the distance between screens (typically 2.5 m) and the reference distance from the muzzle (15 m for rifles, 5 m for pistols). It sets acceptable coefficients of variation (Cv) for velocity—usually 2% or less for service ammunition.

: Safeguards military personnel handling munitions across all logistical phases, including warehousing, rugged transport, and active deployment.
