The EMI/EMC experts at the Applied Technical Services Family of Companies (ATS FoC) conduct RS105 testing to verify equipment enclosure compliance and safety.
RS105 testing determines if an equipment enclosure can withstand a transient electromagnetic field. Under MIL-STD-461G, this method applies to specified equipment and subsystem enclosures exposed to external electromagnetic environments. We conduct RS105 testing under controlled conditions and align each test with program requirements.
What Does RS105 Testing Simulate?
RS105 uses a fast transient field to assess enclosure response. MIL-STD-461G specifies the required waveform and amplitude, with equipment operating and monitored during exposure. The goal is to confirm the enclosure can withstand the specified transient electromagnetic field.
Unlike continuous-wave radiated susceptibility testing, RS105 focuses on a short-duration pulse with strict rise-time requirements. Specialized generation, measurement, and safety controls are essential to the test. The test setup places equipment within a verified field region. Sensors and measurement devices characterize the pulse before exposure. These checks ensure the environment matches approved procedures and that recorded data supports future review.
Who Needs RS105 Testing for EMI Compliance?
RS105 is typically required for defense equipment exposed to transient electromagnetic environments. MIL-STD-461G specifies its use for certain equipment and subsystem enclosures, such as surface-ship and Army aircraft installations. Program documents may further define its applicability.
- Defense equipment manufacturers
- Subsystem and platform integrators
- Prime contractors managing supplier qualification
- Government teams reviewing immunity evidence
The contract, equipment specification, and approved test plan determine RS105 applicability. We review these documents before scheduling to ensure the method is only applied when required.
How Do We Prepare and Perform an RS105 Test?
Preparation includes reviewing equipment configuration, operating modes, cable interfaces, monitoring methods, and acceptance criteria. We also assess physical fit, test volume, support equipment placement, and safety controls. The unit must be monitored to detect any significant response during and after each pulse.
Our team completes setup and calibration, then exposes the equipment according to the approved sequence. MIL-STD-461G requires both pulse polarities and at least five pulses at a controlled repetition rate. Project-specific instructions are included in the final test basis.
- Requirement and configuration review
- Measurement-system checks and setup verification
- Controlled pulse application
- Functional monitoring and documented observations
What Can RS105 Test Results Support?
RS105 results support qualification records, engineering assessments, and customer compliance reviews. Reports should specify what was tested, operational conditions, applied criteria, and any observed responses, as well as note any deviations or limitations.
This service is essential because transient fields can disrupt or damage sensitive electronics. Testing provides controlled evidence before deployment and can reveal shielding, bonding, filtering, or interface issues that require further engineering. We conduct RS105 testing with careful planning, specialized controls, and clear documentation in our ISO/IEC 17025:2017-accredited and ISO 9001:2015-registered laboratories.
