3.Temperature/Humidity Testing
3.1Test Procedure
Temperature/Humidity Testing was carried out according to sections 2.2.7.3 through 2.2.7.8 of NEMA TS 2-2003(R2008)
Low-Temperature Low-Voltage Test Procedure:
While at room temperature, adjust the input voltage to the test unit’s low voltage limit (specified in section 3.2 of this document) and verify that the test unit is still operable.
With the test unit cycling, lower the test chamber to -34°C (-30°F) at a rate not exceeding 17°C (30°F) per hour. Allow the test unit to cycle for a minimum of 5 hours at -34°C (-30°F) with the humidity controls in the off position. Then operate the test unit as necessary to determine that all functions are operable.
Power shall then be removed from the test unit for a minimum period of 5 hours. Upon restoration of power, the test unit shall go through its prescribed start-up sequence and then resume cycling. While at -34°C, operate the test unit as necessary to determine that all functions are operable.
Low-Temperature High-Voltage Tests
While the temperature is at -34°C from the previous test and with the humidity controls off, adjust the input voltage to the high input voltage range on the unit under test and allow the unit to cycle for 1 hour. Then operate the test unit as necessary to determine that all functions are operable.
High-Temperature High-Voltage Tests
With the chamber temperature at -34° from the previous test and with the unit under test cycling, raise the test chamber to +74°C at a rate not to exceed 17°C per hour. Verify the input voltage is at the high limit of the unit under test’s voltage input range.
Set the humidity controls to not exceed 95% relative humidity over the temperature range of 4.4°C to 43.3°C. When the temperature reaches 43°C, readjust the humidity control to maintain constant absolute humidity resulting in the levels shown in the table below. Verify that the test unit continues to cycle satisfactory during the period of temperature increase and at established levels of relative humidity.
Allow the unit under test to cycle for a minimum of 15 hours at 74°C and 18% relative humidity. Then operate the test unit as necessary to determine that all functions are operable.
High-Temperature Low-Voltage Tests
With the temperature chamber at 74°C from the previous test, adjust the input voltage to the unit’s low voltage input level. Then operate the test unit as necessary to determine that all functions are operable.
Test Termination
With the unit under test cycling and the temperature chamber at 74°C, set the controls on the environmental chamber to return to room temperature (16°C to 27°C), with the humidity controls in the off position. The rate of temperature change shall not exceed 17°C per hour.
Failure Definitions
A failure shall be defined as any occurrence which results in other than normal operation of the unit under test. If a failure occurs, the test unit shall be repaired or components replaced, and the test during which the failure occurred shall be restarted from its beginning.

3.3 Test Results
All products listed in Section 2 passed testing without incident.
4.Vibration Testing
4.1Test Procedure
Vibration Testing was carried out according to sections 2.2.8 through 2.2.8.5 of NEMA TS 2-2003(R2008)
This test is intended to duplicate vibrations encountered by the unit under test when installed at its street-corner location.
Resonant Search
With the unit under test securely fastened to the test table, set the test table for a double amplitude displacement of 0.015 inch. Cycle the test table over a search range from 5 to 30 Hz and back within a period of 12.5 minutes. Conduct the resonant frequency search in each of the three mutually perpendicular planes. Note are record the resonant frequency determined from each plane. In the event of more than one resonant frequency in a given plane, record the most severe resonance. If resonant frequencies appear equally severe, record each resonant frequency. If no resonant frequency occurs for a given plane within the prescribed range, 30 Hz shall be recorded.
Vibrate the unit under test in each plane at its resonant frequency for a period of 1 hour at an amplitude resulting in 0.5g acceleration. When more than one resonant frequency has been recorded, the test period of 1 hour shall be divided equally between the resonant frequencies.
The test unit shall be examined to determine that no physical damage has resulted from the vibration tests. Then operate the test unit as necessary to determine that all functions are operable. A failure shall be defined as any occurrence which results in other than normal operation of the unit under test.
4.2Test Results
All products listed in Section 2 passed testing without incident.
5.Shock Testing
5.1Test Procedure
Shock Testing was carried out according to sections 2.2.9 through 2.2.9.4 of NEMA TS 2-2003(R2008)
The purpose of this test is to determine that the test unit is capable of withstanding the shock (impact) to which it may reasonably be subjected during handling and transportation in the process of installation, repair, and replacement. It is to be noted that the test unit is not, at this time, in its shipping carton.
The test unit shall be firmly fastened to the specimen table. In each of its three planes the test unit shall be dropped from a calibrated height to result in a shock force of 10g ±1g. The test unit should then be checked for any physical damage. Then operate the test unit as necessary to determine that all functions are operable. A failure shall be defined as any occurrence which results in other than normal operation of the unit under test.
5.2Test Results
All products listed in Section 2 passed testing without incident.
6.Conclusion
All the products lined in Section 2 of this document have been found to pass temperature/humidity, vibration, and shock testing specified in the NEMA TS 2-2003(R2008) documentation.
