This document outlines a set of minimal standard environmental test conditions categories and corresponding test procedures for airborne equipment for the entire spectrum of aircraft from light general aviation aircraft and helicopters through the jumbo jets and supersonic rtca do 160d categories of aircraft.
DO, Environmental Conditions and Test Procedures for Airborne Equipment is a standard for the environmental testing of avionics hardware. Rtca do 160d test determines whether the equipment interconnect circuit configuration will accept a level of induced voltages caused rtca do 160d the installation environment. This test verifies the test articles ability to survive multiple exposures of salt fog and drying and the environment’s ability to cause accelerated corrosion.
The power input tests simulate conditions of aircraft power from before engine start to after landing including emergencies. Aviation related fluids susceptibility including a variety of fluids ranging from carbonated rtca do 160d beverage to various cleaners and solvents. Retrieved from ” https: This test determines whether equipment can 160dd rtca do 160d effects of voltage spikes arriving at the equipment on its power leads, either AC or DC.
RTCA DO Testing to DO D, E & F
This test determine performance characteristics for equipment that must operate when exposed to icing conditions that would be encountered under conditions of rapid changes in temperature, altitude and humidity. The DO document was first published on February 28, to specify test conditions for the design of avionics electronic hardware in airborne systems.
The user rtca do 160d the standard must also decide interdependently of the standard, how much additional test margin to allow for uncertainty rtca do 160d test conditions and measurement in each test. This page was last edited on 6 Mayat These tests subject the test article to various scenarios of dripping water or pooled water to verify the unit will fully operate in the given condition.
The norm describes the test procedure for airborne equipment. Views Read Edit View history.
The norm defines the different temperature profiles under which the equipment must be tested. This tests determine whether equipment material is adversely affected by fungi under conditions favorable for their development, namely, high humidity, warm rtca do 160d and presence of inorganic salts.
Since then the standard has undergone subsequent revisions up through Revision G.
Factors tested include dielectric strengthcooling under low pressure, and resilience to rapid change rtca do 160d air pressure. From Wikipedia, the free encyclopedia. These tests subject the unit to an environment of blowing sand and dust of specific particle sizes in which the unit must operate at the end of exposures.
Rtca do 160d unit must operate and be subjected to any actuation including knob turns and button pushes and not ignite the environment. This aircraft type dependent test checks the effects of mechanical shock. Input power conducted emissions and susceptibility, transients, drop-outs and hold-up. Rtca do 160d safety test insures the item does not become a projectile in a crash.
Due to the variety of aircraft, the equipment are classified in categories. Direct and indirect effects depending on mounting location; includes induced transients into the airframe or wire bundle.
This checks the effects of temperature on the system.
Typically moisture sensitive devices have issues with this test and require conformal coat rtca do 160d other types of rtca do 160d. These tests under humidity check the effects of high concentrations of humidity and the articles ability to withstand moisture effects.
The Standard Includes Sections on:. These tests exercise the assemblies capability of surviving extreme temperature changes and the effects of differing coefficients of thermal expansion. Condensation also can be a factor coming from cold temperatures. These tests subject the test rtca do 160d to an environment under vacuum, with a gaseous mixture of combustibles. These frequency components are normally harmonically related to the power source fundamental frequency.
The purpose of these tests is to provide a controlled laboratory means of assuring the performance characteristics of airborne equipment in environmental conditions similar of those which may be encountered in airborne operation of the equipment.
The standard environmental test conditions and test procedures contained within the standard, may be used in conjunction with applicable equipment performance rgca, as a minimum specification under environmental conditions, which can ensure an adequate degree of rtva in performance during ttca aboard an rtca do 160d vehicle. This section relates specifically to interfering signals related to the power frequency and its harmonics, audio frequency signals, and electrical transients that are generated by other on-board equipment or systems and coupled to 160s circuits within the EUT through its interconnecting wiring.
