Safety and Standards


The MIL-STD-810G test series are approved for use by all departments and agencies of the United States Department of Defense (DoD). MIL-STD-810G addresses a broad range of environmental conditions that include: low pressure for altitude testing; exposure to high and low temperatures plus temperature shock (both operating and in storage); rain (including wind blown and freezing rain); humidity, fungus, salt fog for rust testing; sand and dust exposure; explosive atmosphere; leakage; acceleration; shock and transport shock; gunfire vibration; and random vibration. The standard describes environmental management and engineering processes that can be of enormous value to generate confidence in the environmental worthiness and overall durability of a system design.

MIL-STD-461 is a United States Military Standard that describes how to test equipment for electromagnetic compatibility.

Specifically, MIL-STD 461F details testing specification to ensure the conducted emissions (CE), conducted susceptibility (CS), radiated emissions (RE), and radiated susceptibility (RS) of a system can meet the requirements for the control of electromagnetic interference.

MIL-STD-461 Method - CE101 / CE102 Conducted Emissions
MIL-STD-461 Method - CS101 / CS106 / CS109 / CS114 / CS115 / CS116 Conducted Susceptibility
MIL-STD-461 Method - RS101 / RS103 Radiated Susceptibility
MIL-STD-461 Method - RE101 / RE102 Radiated Emissions

IEC 60068-2-27


The EN50155 standard is a guidebook that governs the design and testing of electronic equipment used on railway vehicles and related rail applications. To meet the EN50155 requirement, the components must go through a series of strict tests including EMC, cooling, damp heat, salt mist, vibration, and shock tests.

IEC 61373

This International Standard specifies the requirements for testing equipment for railway vehicles which are subjected to vibrations and shock. To ensure the operation of the equipments, it has to withstand tests of reasonable duration to simulate the service condition throughout its expected life.

Simulated long-life testing is achieved by amplification, where amplitudes are increased and the time base decreased.

Test carried out on Winmate Equipment using test values for Category 1 Body Mounted, Class B, which is defined as anything mounted inside an equipment case which is turn mounted directly on or under the car body.
