Test Standards

Standard Tests

All of our end products have undergone the IEC/EN60945 test regime. The equipment standard used is “Protected Equipment“.

Performance criteria used is “A”.

Environmental tests:

 Extreme power supply (EPS)  AC Voltage ±10 %   Frequency ±5 %
DC Voltage +30 %  -10%
Must also be performed during some of the climatic tests!
 Dry heat including EPS  +55 °C  PT
With EPS
 Damp heat  +40 °C 93 % relative humidity 1 cycle EPS
 Low temperature including EPS  –15 °C PT
With EPS
 Vibration Sweep 2 Hz – 13,2 Hz at ± 1 mm, 13,2 Hz – 100
Hz at 7 m/s2 and for 2 h on each resonance (Q>5),
2h on one resonance / observed frequency (Q<5) , otherwise (Q=0) 2 h at 30 Hz in all three axes.
Power cycle during and after the test

There is also an extensive EMC / EMI part of this test standard.

For the complete specification please contact CENELEC.

Safety tests

Every unit undergo ground bond and power supply isolation testing prior to shipment.

Additional Tests:

Some units, as the RSCC, have undergone an imitated MIL-S-901 shock test. The test is performed using an air controlled anvil. An example of that process that can be seen here.

Shock tests

The shock test method described  IEC 60068-2-27 using severities described in the following table:

Orientation on Ship
Base input test pulse
Number of shocks
Vertical 80g/8ms half sine
(tolerance: plus 5g, minus 0g)
(Athwart ships and Longitudinal)
40g/8ms half sine
(tolerance: plus 5g, minus 0g)
 6 (3 per axis)

Vibration tests

The test method is specified in IEC 60068-2-6 and modified in accordance with section of MIL-HDBK-2036.

The unit shall maintain its specified performance during and after being subject to the test method specified in IEC 60068-2-6 using vibration severity levels specified in the following table :

Frequency Range (Hz)
 Amplitude (mm)
4 – 10 0.760
11 – 15 0.760
16 – 25 0.510
26 – 33 0.250
34 – 40 0.130
41 – 50 0.076
