MILITARY MODELS
Military test conditions MIL STD202
Our patented bended edge membranes permit us to
realize military applications. We deliver since more
than 30 years piezo acoustic components on military
specifications.
Our products are used in portable radio's, de-icing
detection, airplane cockpit alarms...
We are since more than 20 years Navo approved for
several models.
We warned in time at critical moments...
The different tests are summarised below. The detailed procedures are available upon special
request.
Thermal shock test 107 method A: The thermal shock test is performed to determine the
resistance of a part to exposures at extremes of high and low temperatures, and to the shocks of
alternate exposures to these extremes, such as would be experienced when equipment or parts
are transferred to and from heated shelters in arctic areas. The products are exposed to a flow of air
at different temperatures for at least 5 cycles.
Humidity test 103 method B: This test is performed to evaluate the properties of materials used in
components as they are influenced by the absorption and diffusion of moisture and moisture
vapour.
This accelerated environmental test is accomplished by the continuous exposure of the specimen
to high relative humidity at an elevated temperature during 96 hours.
Salt spray test 101 method A: The purpose of this test is to define if the product is resistant to salt
spray. This accelerated laboratory corrosion test simulates the effects of seacoast atmospheres on
metals. The coating of the product is subjected to a fine mist of salt solution during 96 hours.
Shock test 213B method H: The shock test (Sawtooth pulse during 6Ms) is conducted for the
purpose of determining the suitability of component parts and subassemblies of electrical and
electronic components when subjected to shocks such as those which may be expected as a result
of rough handling, transportation and military operations. The design of the shock machine is not
specified, but shock pulse waveforms are specified with tolerances.
