Description of tests and procedures; 

ATA Specification 300 Category 1

Airline transport container suitable for a minimum of 100 airline trips
Impact Resistance Test; samples were exposed to impact using a bar weighing 13.2lbs with a hemispherical end of 3.2cm.Bar was dropped with its longitudinal axis vertical on to each sample’s weakest point from a height of 0.5m. Samples were conditioned to a temperature of -20°C before impact exposure.

ASTM D-4169 DC-18

Level 1 Schedule A Handling (Manual)
Drop tests – a series of drops on each edge, corner and face of the case from a height of no less than 48cm(19”) and with loads of 6.8-31.8kg(15-70lbs) determined by case size. Samples were conditioned at lab ambient conditions and then temperatures of -28°C and +60°C for a minimum of 3 hours at each condition.

ASTM D-4169 DC-18

Level 1, Schedule F loose load vibration Vibration – The cases are tested using test method D-999 to determine the ability to withstand the repetitive shocks occurred during transportation of loose loads.

ASTM D-4169 DC-18

Level 1, Schedule H Environmental Hazard Rainfall
Simulated rainfall for 2hrs at a rate of 10cm/hr (4”). Samples were conditioned to -20 degrees C and +52 degrees C.


Method 512.4
Immersion – The case is submerged in a basin of water to a depth of 1 meter (3.28 ft) to the top most part of the case for30 minutes. The case is heated to 10 degrees F higher than the temperature of the water.

IP 67 ingress protection

6- Total protection from dust
7- Protected against the effects of immersion between 15cm (5.9”) and 1m(39.37”)
Samples exposed to 8hr dust exposure with a concentration of 2 kg/m3 using talcum powder as dust. Samples exposed to immersion in 1 meter of water for a period of 30 minutes.
