Does 160 have indirect lightning?

Does 160 have indirect lightning?

DO-160 lightning induced transient susceptibility or indirect lightning is typically the most severe transient test in all of DO-160. However, cable bundle testing requires the unit to operate through the lightning strike making the unit more susceptible to failure.

DO-160 lightning test?

DO-160 specifies several canonical wave forms which emulate Lightning Induced Transients. The standard defines a series of prototypical waveforms which are used to apply current and voltage to the interface pin of the unit under test.

What is pin injection?

Pin injection uses a fixed energy level, calibrated before the test and applies it to each pin of your unit. The VOC represents an open circuit voltage and the ISC represents a short circuit current. The waveform generator’s amplitude is increased until an open circuit voltage at the required level is achieved.

Do 160g Do section 16?

RTCA/DO-160 Section 16 test procedures are used to determine whether the EUT can operate during different AC and/or DC power variations that occur during normal and emergency aircraft operation.

What is the latest MIL-STD-810?

MIL-STD-810, Environmental Engineering Considerations and Laboratory Tests, is a United States Military Standard that emphasizes tailoring an equipment’s environmental design and test limits to the conditions that it will experience throughout its service life, and establishing chamber test methods that replicate the …

Is a 160 temperature range?

Temperature testing consists of non-operational ground survival temperatures as low as -55 C and operational high temperatures of 70 C. Altitude testing as high as 70,000 feet as well as decompression (emergency descent) and overpressure testing (routine aircraft pressurization system testing) is also required.

What is the difference between MIL-STD-810G and MIL-STD-810H?

A MIL-STD-810G-certified server may undergo a combination of assessments for resistance to gunfire shock, pyroshock, acoustic noise, immersion, contamination by fluids – any of the methods listed in document. Photo: MIL-STD-810H includes changes to Acceleration, High Temperature, Low Temperature, Vibration, and more.

Can you do a 160 temperature test?

The purpose of DO-160 temperature variation testing is to assess the performance characteristics of airborne equipment when exposed to sudden, extreme changes in temperature. This procedure includes five categories that address temperature change rates for equipment installed in or on aircraft.

What are the requirements for indirect lightning strikes?

They draft and publish the recommended requirements for Indirect Lightning Strikes, based largely on industry and SAE research and knowledge. These requirements are very often adopted into RTCA by the RTCA SC-135 subcommittee, who is responsible for the content of DO-160.

What are the fundamentals of do-160f, section 22?

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.

What are the waveforms of an indirect lightning generator?

Indirect lightning test generators produce high voltage and high current impulses: waveforms 1, 2, 3, 4, 5A, 5B and 6 may be applied at different levels depending on the location, shielding, protection level of the equipment under test (EUT).

What is the purpose of an indirect lightning test?

Indirect lightning test is applicable to airborne equipment in different functional states. The purpose of the test is to simulate indirect effects produced by lightning strike with a test system and observe/asses the behaviour of EUT.
