TREKKER-X4, a smartphone satisfying military standards (and Mike Horn)
The MIL-STD-810G military standards were created by the US Army test laboratory for equipment to be developed. These standards involve several tests to be performed in a laboratory. The purpose: re-create extreme, hostile and dangerous conditions that may occur in a real professional environment. To ensure TREKKER-X4 compliance with these standards our teams selected a set of 12 tests, that it passed with excellence, reflecting situations that users are likely to experience while using their smartphone. Here’s an explanation by CROSSCALL.
RESISTANCE TO EXTREME TEMPERATURES
1. TEMPERATURE SHOCK
The TREKKER-X4 can pass from -40°C to +60°C in less than a minute (repeated 3 consecutive times).
2. HIGH TEMPERATURE
When stabilised at a temperature of 60°C for over 4 hours, the TREKKER-X4 won’t show any sign of surface deterioration. Its functional use (calls, sms’s…) is guaranteed at 71°C for 2 hours.
3. LOW TEMPERATURE
When stabilised at a temperature of -51°C for 4 hours, the TREKKER-X4 won’t show any sign of surface deterioration. Its functional use (calls, sms’s…) is guaranteed at -40°C.
The TREKKER-X4 is exposed to harsh weather conditions for 30 minutes on each one of its 6 faces i.e. 3 hours of harsh conditions (a flow of 10cm/hr i.e. droplets of up to a 4.5-mm diameter with bursts of 65 km/hr).
5. SALT FOG
A sodium chloride solution (5%, neutral pH) is sprayed on the TREKKER-X4. Spraying and drying are then alternated in cycles of 24 hours for 4 days in very warm conditions (temperature of 35°C).
6. CONTAMINATING FLUIDS
A solvent (2-propanol) is sprayed for 24 hours.
RESISTANCE TO MOTION
The TREKKER-X4 undergoes prolonged exposure (8 hrs) to heavy shaking on every axe (X,Y,Z).
8. SHOCK TESTING
18 shocks are performed i.e. 3 on each of the 6 faces.
Acceleration is performed on the TREKKER-X4 along the 6 directions, passing from 0 to 72 km/hr in 1 second.
RESISTANCE TO SEVERE WEATHER CONDITIONS
10. RESISTANCE TO ALTITUDE (low pressure)
The TREKKER-X4 is switched on for an hour in a depressurized chamber at 57kPa which corresponds to using the phone at over 4000 metres.
11. SUN (UV) RADIATION
The TREKKER-X4 is exposed to conditions that correspond to spending over a week in the areas of the world that are most exposed to UV rays (using Xenon lamps to reproduce sunlight wavelengths, from ultraviolet to infrared). This test is carried out with an exposure peak of 1120W/m2 inducing a temperature with a potential to reach 49°C.
12. ICE/FREEZING RAIN
The TREKKER-X4 is stabilised at 0°C. Then it’s hit by a cold-water jet for an hour at a temperature of around -10°C until a 13-mm ice layer is formed on the phone. The ice is then kept there for another 4 hours. The TREKKER-X4 smartphone is still functional after defrosting.
Certified = no alteration in look, materials or functional features after testing.
