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:
| TEST | REQUIREMENTS |
| 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.
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) |
3 |
| Horizontal (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 5.1.2.17.1 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)
