Do 160 Section 22

Rtca do 160 section 22 offers test procedures to determine whether the eut can operate as specified during and or after various lightning induced transient waveforms are injected into connector pins interconnecting cables and power leads using pin injection and or cable bundle tests.

Do 160 section 22. There are five levels for internal aircraft equipment and interconnecting wiring. Rtca do 160 section 21 0 emission of radio frequency energy. Do 160 section 22 allows equipment to be tested to an appropriate anticipated exposure level consistent with the expected use and installation location on the aircraft.

The wave forms and levels and the pass fail criteria for equipment performance during the test shall be listed in the applicable equipment specification. We understand the need for fast accurate testing that can be turned around on a tight schedule. These tests determine that the equipment does not emit undesired rf noise in excess of the levels specified below.

Lightning induced transient susceptibility is intended to simulate lightning events striking the airplane and coupling onto your product s interconnecting cables. The pin injection method is normally used to show damage tolerance while the cable bundle tests are normally used to show upset tolerance. Rtca do 160 section 22 0 lightning induced transient susceptibility.

Generator for do 160 ed 14 section 22 indirect lightning test on aircraft. Section 22 0 lightning induced transient susceptibility. Do 160 figure 21 6 typical setup for conducted rf interference test.

We re fully accredited to perform all aspects of do 160 testing including section 22 and 23 for lightning simulation. Generator for complete aircraft testing with reduced current amplitude max 5ka maximum energy 26kj wf1 6 4 70µs. The fundamental document that defined the environment and test waveforms used in do 160 section 22 and accounted for the lightning data and analysis necessary to support these requirements is sae arp5412 aircraft lightning environment and related test waveforms originally published in 1999 and revised to revision a in 2005.

22 0 and 23 0. Single stroke generator according to do 160 section 22. 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 sensitive circuits within the eut through its interconnecting wiring.
