RTCA DO-160 – Section 25.0 – Electrostatic Discharge
SCOPE
The Electrostatic Discharge test relates to airborne equipment which may be involved in static electricity discharges from human contact.
Some factors contributing to an ESD event may be: low relative humidity, temperature, use of low conductivity (artificial fiber) carpets, vinyl seats and plastic structures which may exist in all locations within an aircraft.
This test is applicable for all equipment and surfaces which are accessible during normal operation and/or maintenance of the aircraft. This test is not applicable to connector pins.
PURPOSE OF THE TEST
The electrostatic discharge test is designed to determine the immunity or the ability of equipment to perform its intended function without permanent degradation of performance as a result of an air discharged electrostatic pulse.
TEST DESCRIPTION
The immunity to electrostatic discharge shall be determined by the ability of the equipment under test (EUT) to withstand a series of electrostatic discharge pulses at a test level of 15,000 volts, directed at specific human contact locations on the EUT.
The quantity of pulses shall be ten (10) in each of the selected locations and in both positive and negative voltage polarities (10 positive and 10 negative).
DO-160 is a standard for environmental test on avionics equipment published by RTCA, the Radio Technical Commission for Aeronautics. The DO 160 G was amended and now all guideline inside it are replaced by the DO 357. |
