Chinese Military Standard
GJB 151B-2013 is China's national military standard, whose full name is "Electromagnetic Emission and Sensitivity Requirements and Measurements for Military Equipment and Subsystems." This standard specifies the requirements and measurement methods for electromagnetic compatibility of military equipment and subsystems. It is an electromagnetic compatibility test standard that military products must comply with to ensure that military equipment can operate normally in various electromagnetic environments without causing unacceptable electromagnetic interference to other equipment. GJB 151B-2013 testing services are usually provided by third-party testing agencies with relevant qualifications. These agencies usually have military confidentiality qualifications, CNAS (China National Accreditation Service for Conformity Assessment) qualifications, CMA (China Metrology Certification) qualifications, and DILAC (Defense Science and Technology Industry Laboratory Accreditation Board) qualifications, etc. These qualifications prove the professionalism and authority of the testing agency and ensure the accuracy and recognition of its test results.

GJB 151B-2013 testing services include but are not limited to the following items:
1. CE101 25Hz~10kHz power line conducted emissions:
Tests the electromagnetic emissions generated by power lines from equipment within a specified frequency range.
2. CE102 10kHz~10MHz power line conducted emissions:
Tests electromagnetic emissions generated by power lines in the high frequency range from equipment.
3. CE106 10kHz~40GHz antenna port conducted emission:
Tests the electromagnetic emissions generated by the equipment through the antenna port in the ultra-high frequency range.
4. CE107 power line spike signal (time domain) conducted emission:
Test equipment generates spikes on power lines that emit signals.
5. CS101 25Hz~150kHz power line conduction sensitivity:
Tests the sensitivity of equipment to electromagnetic interference on power lines.
6. CS103 15kHz~10GHz antenna port intermodulation conduction sensitivity:
Tests the sensitivity of the equipment to intermodulation interference at the antenna port.
7. CS104 25Hz~20GHz antenna port unwanted signal suppression conduction sensitivity:
Test the sensitivity of the equipment to unwanted signal suppression at the antenna port
8. CS105 25Hz~20GHz antenna port intermodulation conduction sensitivity:
Tests the sensitivity of the equipment to intermodulation interference at the antenna port.
9. CS106 power line spike signal conduction sensitivity:
Tests the sensitivity of equipment to interference spikes on power lines.
10.CS109 50Hz~100kHz shell current conduction sensitivity:
Tests the sensitivity of equipment to electromagnetic interference generated by case current.
11.CS114 10kHz~400MHz cable bundle injection conduction sensitivity:
Tests the sensitivity of equipment to electromagnetic interference injected through cable bundles.
12. CS115 cable bundle injection pulse excitation conduction sensitivity:
Tests the sensitivity of equipment to pulsed electromagnetic interference injected by cable bundles.
13.CS116 10kHz~100MHz cable and power line damped sinusoidal transient conduction sensitivity:
Test the sensitivity of equipment to damped sinusoidal transients on cables and power lines
14.RE101 25Hz~100kHz magnetic field radiation emission:
Test equipment for radiated emissions in magnetic fields.
15.RE102 10kHz~18GHz electric field radiated emission:
Radiated emissions from test equipment in electric fields.
16.RS101 25Hz~100kHz magnetic field radiation sensitivity:
Tests the sensitivity of equipment to magnetic field interference.
17.RS101 25Hz~100kHz magnetic field radiation sensitivity:
Tests the sensitivity of equipment to magnetic field interference.
18.RS103 10kHz~40GHz electric field radiation sensitivity:
Tests the sensitivity of equipment to electrical field interference.
19.RS105 transient electromagnetic field radiation sensitivity:
Tests the sensitivity of equipment to transient electromagnetic fields.
When choosing GJB 151B-2013 testing services, you should ensure that the testing agency has the appropriate qualifications and capabilities to ensure the effectiveness and authority of the test. Through these testing services, SRC-TEST can ensure that military equipment and subsystems have good electromagnetic compatibility performance in complex electromagnetic environments.
