MIL-STD 461 Testing

Communication Certification Laboratory (CCL) is pleased to announce we are now offering EMC Compliance testing to MIL-STD 461. MIL-STD 461 was published to determine the requirements for the control of electromagnetic interference characteristics of subsystems and equipment for applicable Military and Aerospace requirements. MIL-STD 461 has various issues starting with revision A and up the current revision E. MIL-STD 461 revision F has been published and is beginning to be implemented into current Military contracts.

MIL-STD 461 is basically divided into two areas, Emissions and Susceptibility. The electromagnetic effects are either conducted or radiated.

MIL-STD 461 establishes the requirements for Conducted Emissions, Conducted Susceptibility, and Radiated Emissions Radiated Susceptibility. The table below details the specific test call out in the current issue of MIL-STD 461E.

Communication Certification Laboratory can perform MIL-STD 461 E testing on many different products that require compliance to the MIL-STD 461 E standard. Most devices that are used by each branch of the armed services require MIL-STD 461 E testing. Depending on the product or component and which branch of the armed services the device or component is being sold to, will depend on what is required from the MIL-STD 461 E standard. Not all tests are required for each device, component or application. The MIL-STD 461 E standard has a test matrix that identifies the applicable testing needed.
