AREMA 12.5.1 Switch Circuit Controllers Testing

AREMA 12.5.1 recommends instructions that apply to the installation, maintenance and test of switch circuit controllers. Testing under the AREMA C&S Manual specifies environmental test requirements that various products must meet. These tests can include temperature extremes, humidity, vibration (sinusoidal and sine sweep), mechanical shock, electromagnetic interference, dielectric requirements, corrosion and abrasive environment.

The specific requirements of the testing each device must meet is primarily determined by the position on the train the device is located. The bottom of this page includes a list of all of the classes and mounting positions.
