2. Equipment categories

Equipments are categorized as a function of the environments to which they are subjected during normal operation.

3. Sections

Sections 7 and 8 are aircraft dependent.

§	Name	Concerns the effects of…	Parameters of interest
1	Introductory sections	N/A	N/A
2
3
4	Temperature	Temperature on the system.	Temperature, condensation.
4	Altitude	Altitude & cabin depressurization on performance.	Dielectric strength, (rapidly) varying air pressure.
5	Temperature Variation	Extreme temperature changes.	Temperature delta, thermal expansion coefficients.
6	Humidity	High concentrations of humidity; ability to withstand moisture effects.¹	Hygrometry.
7	Shock & Crash safety	Mechanical shock. Ensures the item does not become a projectile in a crash.	Potential for projectile behavior.
8	Vibration	Vibrations.	Normal operation in all vibration scenarios.

10	Water proofness	Dripping water or pooled water.	Normal operation after exposure.
11	Fluids susceptibility	Various fluids including carbonated sugared beverages and cleaners/solvents.	Normal operation after exposure.
12	Sand & Dust	Blowing sand and dust of specific particle sizes.	Normal operation after exposure.
13	Fungus Resistance	Fungi under conditions favorable for their development.²	Fungal proliferation.
14	Salt & Fog	Multiple exposures of salt fog and drying; environmentally accelerated corrosion.	Normal operation after exposure.
15	Magnetic effect	Magnetic effects on the aircraft's compass.	Normal aircraft compass function.
16	Power input	Input power emissions, susceptibility, transients, drop-outs, hold-up.³	Voltage, current, phase.
17	Voltage spike	Voltage spikes caused by input power.	AC/DC voltage.
18	Audio Frequency Conducted Susceptibility	Frequency components during normal operation.	Power source harmonics.
19	Induced Signal Susceptibility	Induced voltages in the equipment interconnect circuit configuration.	power frequency harmonics; audio frequency signals, electrical transients.
20	RF emission and susceptibility	Normal operation on radio frequency emission energy and susceptibility.
21
22	Lightning susceptibility	Direct and indirect effects, depending on location.	induced transients in the airframe or wire bundle.
23
24	Icing	Icing conditions arising from rapid changes in temperature, altitude and humidity.	Presence of ice.
25	ESD	ESD in handling and operation.	ESD.
26	Flammability	Normal operation on presenting a fire hazard.	Normal operation not causing a fire.

Footnotes:

Moisture sensitive devices may experience issues with this test and require conformal coat or other types of protection.

This includes high humidity, a warm atmosphere, and the presence of inorganic salts.

Full flight mission must be considered, from prior to the engine start, to after landing—including emergencies.
