TREKKER-X4, military-standard-proof (and Mike Horn-proof)

The MIL-STD-810G military standard was created by the US Army's Equipment Development Test Laboratory. It comprises a series of laboratory tests. The aim is to recreate the extreme, hostile and dangerous conditions encountered in real-life working environments. To ensure that the TREKKER-X4 meets this standard, our teams selected a battery of 12 tests, which it passed with flying colors, corresponding to situations of use that our users might experience. CROSSCALL deciphers them for you.

RESISTANCE TO EXTREME TEMPERATURES

1. Thermal shock

The TREKKER-X4 goes from -40°C to +60°C in less than a minute (repeated 3 times in a row).

2. High temperature

Stabilized at a temperature of 60°C for over 4 hours, the TREKKER-X4 shows no sign of aesthetic degradation. It remains functional (calls, sms...) at 71°C for 2 hours.

3. Low temperature

Stabilized at a temperature of -51°C for 4 hours, the TREKKER-X4 shows no signs of aesthetic degradation. It remains functional (calls, sms...) at -40°C.

LIQUID RESISTANCE

4. Rain

The TREKKER-X4 is exposed to severe weather for 30 minutes on each of its 6 sides, i.e. 3 hours of difficult conditions (flow rate of 10cm/h, i.e. droplets up to 4.5 mm in diameter, with gusts up to 65 km/h).

5. Salt spray

The TREKKER-X4 is sprayed with a sodium chloride solution (5%, pH neutral). The TREKKER-X4 then undergoes alternating spraying/drying in 24-hour cycles for 4 days, under high heat (35°C).

6. Liquid contamination

A solvent (2-propanol) is sprayed on for 24 hours.

RESISTANCE TO MOVEMENT

7. Vibration

The TREKKER-X4 is exposed for prolonged periods (8h) to severe shocks along each axis (X, Y, Z).

8. Shocks

18 shocks are performed, i.e. 3 shocks on each of the 6 faces.

9. Acceleration

The TREKKER-X4 is accelerated in all 6 directions from 0 to 72 km/h in 1 second.

RESISTANCE TO HARSH WEATHER CONDITIONS

10. Resistance to altitude (low pressure)

The TREKKER-X4 is switched on for 1 hour in a 57kPa depressurized chamber, equivalent to use at over 4,000 meters.

11. Solar radiation (UV)

The TREKKER-X4 is exposed to conditions that correspond to more than a week in the world's most UV-exposed locations (using Xenon lamps to reproduce the wavelengths of sunlight, from ultraviolet to infrared). The test is carried out at a peak exposure of 1120W/m2, inducing temperatures of up to 49°C.

12. Ice / freezing rain

The TREKKER-X4 is stabilized at 0°C. It is then sprayed with cold water for 1 hour at an ambient temperature of -10°C, until 13 mm of ice has formed on the phone. The ice is maintained for a further 4 hours. The TREKKER-X4 remains functional after defrosting.
