FDOT / NEMA STANDARDS

Environmental testing verifies that the product operates properly under the field conditions of the expected installation site and typically includes temperature, humidity, vibration, shock, and electrical variations. This aspect of testing is usually the most extensive and complex required for any product.

There are a number of industry-accepted references for the environmental and electrical requirements; these include NEMA TS2 and TS4 for dynamic message signs (DMS). These standards apply to various traffic controllers/sensors. A2Z is able to perform the environmental and electrical testing associated with NEMA TS2 and TS4 standards including but not limited to: temperature and humidity, vibration and shock, and power interruptions, voltage transients, and power line voltages during which the equipment must operate properly.
