2.8.2 Mains transients
The equipment functions and is undamaged in the presence of mains-borne interference having
voltage spikes detailed as follows:
Frequency: 0.2 times mains frequency
Rise Time: 5ns
Half-Pulse width duration: 50ns
Polarity: +ve or-ve
Phase Angle: Free, non-synchronous
Peak Voltage: 1000V does not cause malfunction (soft errors)
1500V does not cause physical damage, but visible
malfunction is permitted
2.8.3 Electrostatic discharge
The equipment function is undamaged when subjected to a discharge (at both +ve and -ve polarity)
from a 5pF capacitor charged to a voltage specified below, limited by a 150 resistor. The
discharge is applied to any user accessible points, interconnecting cables and also the ground
reference plane adjacent to the equipment.
Discharge Voltage: 6kV does not cause malfunc6on (soft errors)
12kV does not cause physical damage, but visible malfunction is
permitted
2.9 Environment
2.9.1 Operating
The equipment operates and functions to specification while under the following environmental
conditions:
Temperature l0 to +35ºC
Relative Humidity 10 to 80% non-condensing
Mechanical Shock Not operating: .40g 1/2 sinusoid l0ms, maximum
repetition rate 1 every10 seconds. 10 shocks on all six faces
Operating: 5g 1/2 sinusoid l0ms, maximum repetition
rate 1 every 10 seconds. 10 shocks on all six faces
Vibration To BS2011 Part 2Fd, vibration in each plane (X,Y and Z).
(Time limit for each test 90 minutes)
Operating: 20 to 500Hz, 0.5G max
(20 to 500Hz at 0.0005G sq/Hz)
Not operating: 10Hz so 200 Hz, 2.0G max
(10 to 200Hz at 0.02G sq/Hz)
