GJB151 is China's national military standard governing electromagnetic emission and susceptibility requirements for military equipment and subsystems — the direct counterpart to MIL-STD-461, covered in our companion article. The two standards are closely related by design.
Version History
GJB151A-1997 and GJB152A-1997, the original pairing, were published and implemented in 1997.
GJB151B-2013 consolidated and revised the standard, replacing both GJB151A and GJB152A.
GJB151C-2024 is the current revision.
Shared Structure With MIL-STD-461
| Category | GJB151 / MIL-STD-461 shared methods (representative) |
|---|---|
| Conducted Emissions | CE101, CE102 |
| Conducted Susceptibility | CS101, CS114 |
| Radiated Emissions | RE101, RE102 |
| Radiated Susceptibility | RS101, RS103 |
Where GJB151 and MIL-STD-461 Genuinely Differ
Limit lines and test levels are set independently by the Chinese standard's own technical committee.
Applicability tables are set independently within GJB151's own structure.
Test setup and procedural detail are specified within GJB151's own documentation.
Why This Matters for Equipment Selection
Chamber and amplifier specifications capable of meeting MIL-STD-461's requirements will, in the great majority of cases, also satisfy GJB151's broadly equivalent requirements.
Practical Summary
| Factor | MIL-STD-461 | GJB151 |
|---|---|---|
| Governing body | US Department of Defense | China's national military standard system |
| Current revision | G (2015), with H published 2026 | C-2024 |
| Test method naming | RE/RS/CE/CS with numbers | Same convention, many shared numbers |
