MIL-STD-461 is a United States Military Standard that defines the requirements for the electromagnetic compatibility (EMC) of equipment and systems used by the military. It was originally developed in the 1960s to ensure that military equipment and systems could operate effectively in the presence of electromagnetic interference (EMI), which can be caused by sources such as radar, communications equipment, and other electronic devices. The standard covers a range of topics related to electromagnetic compatibility, including emission and susceptibility testing, limits on electromagnetic emissions, and requirements for cable shielding and grounding. It defines the requirements for different types of equipment and systems used by the military, including communications equipment, weapons systems, and electronic countermeasure devices.

MIL-STD-461 includes a series of performance requirements and test procedures to ensure that military equipment and systems are designed and manufactured to meet the standard. Compliance with MIL-STD-461 is typically verified through testing during the development and production of the equipment or system. The standard is periodically revised to incorporate new technologies and updates to industry practices. The most recent version of MIL-STD-461 is Revision G, which was published in 2015.

Overall, MIL-STD-461 is an important standard for the military industry and plays a critical role in ensuring the safety and reliability of military equipment and systems. By establishing clear requirements for electromagnetic compatibility, the standard helps to ensure that military equipment and systems are designed and manufactured to a consistent level of quality, regardless of the manufacturer.

BNS compliance with MIL-STD-461, means that the product has been designed and manufactured to meet the electromagnetic compatibility (EMC) requirements specified in the standard. Compliance with MIL-STD-461 is important for military applications where electronic equipment and systems are exposed to potentially hostile electromagnetic environments.

To comply with MIL-STD-461, BNS was tested to verify that it meets the specified emission and susceptibility limits, cable shielding and grounding requirements, and other applicable requirements specified in the standard. The testing was carried out in a laboratory environment under controlled conditions.

Compliance with MIL-STD-461 is an important consideration for military organizations that require network security appliances for use in their equipment or systems, as it indicates that the product has been designed and tested to operate safely and reliably in the presence of electromagnetic interference.
