Altitude Testing

Altitude Testing is utilized by manufacturers of products to ensure product reliability by simulating the effects that altitude and pressure have on products.

CSZ testing services combine temperature, humidity and altitude to test components or sub-assemblies designed for use in a variety of industries.

High altitude tests may be performed to a variety of test specifications including Mil Std-810 to determine if material can withstand and/or operate in a low-pressure environment or rapid pressure changes. We also offer special tests required by the RTCA DO-160 test specification for testing for aircraft avionics.
