Aerospace Product Testing - Clark Testing

Aerospace Product Testing



The aerospace industry has very unique requirements that demand experienced personel and a variety of testing resources. Clark Testing has a long history of supporting aerospace equipment and component manufactures. The broad array of capabilities enables us to create the extreme operating conditions to qualify components for our aerospace customers. Clark Testing provides DO-160 compliant testing services that include: vibration, shock, thermal, thermal shock, vacuum, altitude, acoustics, modal analysis, dynamics response, structural integrity, corrosion, metals analysis, failure analysis, hydraulics, EMC / EMI compliance, oil and lubrication analysis. DO-160 outlines a set of standard environmental tests and corresponding procedures for aurborne equipment covering the entire spectrum of aircraft from light aircraft and helicopters to jumbo jets.

Clark’s rigorous quality program combined with our comprehensive range of testing services provides our clients with a uniquely qualified resource for their product qualification. Our team of experienced engineers and technicians understand the complexity and demands of product development programs and the criticality of timing in these programs

In addition to DO-160 testing, Clark Testing also offers MIL-STD-810 and MIL-STD-461 testing services. MIL-STD-810 testing includes a braod range of environmental conditions including: low and high pressure, low and high temperature, rain and humidity, vibration, shock, and many other simulated conditions.

DO-160 Testing Services


  • DO-160 Section 4.0 Temperature and Altitude
    • Temperature testing checks the effects of temperature on the system, Condensation also can be a factor coming from cold temperatures. Altitude tests check the effects of altitude, including loss of cabin pressure on the device, system, or equipmet.
  • DO-160 Section 5.0 Temperature Variation
    • These tests exercise the assemblies capability of surviving extreme temperature changes and the effects of differing coefficients of thermal expansion.
  • DO-160 Section 6.0 Humidity
    • These tests under humidity check the effects of high concentrations of humidity and the articles ability to withstand moisture effects.
  • DO-160 Section 7.0 Operational Shocks and Crash Safety
    • This aircraft type dependent test checks the effects of mechanical shock. Crash safety test insures the item does not become a projectile in a crash. The norm describes the test procedure for airborne equipment.
  • DO-160 Section 8.0 Vibration
    • Aircraft type dependant test checks the effects of vibration and the equipment's ability to operate during all vibration scenarios.
  • DO-160 Section 10.0 Waterproofness
    • These tests subject the test articles ability to various scenarios of dripping water or pooled water to verify the unit will fully operate in the given condition.
  • DO-160 Section 14.0 Salt Spray
    • 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.
  • DO-160 Section 20.0 Radiated and Conducted Sesceptibility
    • This test combines the RS03 / 103 and CS114 tests under one heading. Conducted susceptibility testing covers the frequency range from 10 kHz to 400 MHz and applies to interconnect cabling. The bulk current injection (BCI) method is used and severity levels vary widely, depending on component location and cable routing. Radiated susceptibility covers the frequency range from 100 MHz to 18 GHz, and is basically the same as the MIL-STD test technique. As with the conducted susceptibility test, severity levels vary widely.
  • DO-160 Section 21.0 Radiated and Conducted Emissions
    • This test combines the conducted and radiated E-field emission tests from MIL-STD-461 under one heading. Although LISNs are specified in the test setups, this standard requires that current be measured using a clamp-on current probe. The frequency range for conducted emissions is 150 kHz to 30 MHz for power lines and 150kHz to 100 MHz for interconnected cables. The radiated emission testing is very similar to RE02 method of 461 and covers the frequency range from 2 MHz to 6 GHz.
  • DO-160 Section 24.0 Icing
    • This test determines performance characteristics for equipment that must operate when exposed to icing conditions.
  • DO-160 Section 25.0 ESD
    • This checks for resilience vs ESD in handling and operation.
