TESTING
All Siemens motors are given a routine line test per NEMA MG1 and IEEE-112.
ROUTINE TEST
Routine test consists of the following items tested in accordance with IEEE standard 112.
• No Load Current
• No Load Speed
• Locked-Rotor Current
• Winding Resistance
• High Potential
• Bearings/Vibration Check
Vibration data is NOT recorded with a routine test.
If required, please add per the following table.
Test report of routine test is based on IEEE Std. 112 Form A-1 and includes complete
nameplate information.

TESTING
CALIBRATION TESTS
Calibration test consists of 0-125% rated load test measurement of speed,
torque, current, power factor and efficiency, at rated voltage. Data is curve
plotted on Siemens standard format. Foot mounted motors only.
NOISE TESTS
Noise test to verify sound levels can be performed. These tests are conducted
per procedures defined in IEEE-85. Tests are performed under no load
conditions.
