Responsible Persons: Waldemar Masur (B&W International GmbH) Johannes Frick (PAConsult GmbH)

Purpose:

By means of a transport simulation an outdoorcase - Type 4000 - is tested to climatic-, vibrationand shock strains. Furthermore a water resistance test is performed. The transport simulation is performed according to the specification of the client: MIL-STD-810G w/Change 1 [1].

Summary:

The tests are performed successfully; visible changes are observed.

During the pre-conditioned drop test on face 3, the closure (buckle) opened halfway. The case opened at the drop on face 1. During the unconditioned drop on face 1 and 3, one closure (buckle) opened halfway. No damages could be detected. The immersion test showed no ingress of water.

The evaluation of the result is performed by the client.

5 Test Procedures

5.1 Temperature Shock

With the EUT in its appropriate logistic configuration, stabilize the EUT at controlled ambient conditions. Transfer the EUT in no more than one minute to an atmosphere at temperature T2 that will produce the thermal shock and stabilize the temperature. Transfer the EUT back to controlled ambient conditions (T1) in no more than one minute, and stabilize the temperature. Repeat this procedure 2 times (3 cycles in total).

T1 = -33°C

T1 = +63°C

Stabilization time: 1 hour per temperature

The test is performed with EUT 1.

Fig. 2 and 3 show the setup in the two different chambers.

Page 9 of 25 Test Report 17-8981 Outdoorcase

5.2 Drop Test

The EUT is dropped immediately after the end of the third temperature cycle with a temperature of + 63°C. The EUT is dropped from a height of 1.220 mm. It is dropped on all faces (6 drops), all edges (12 drops) and all corners (8 drops.). Fig. 4 shows the setup exemplarily.

The test is performed with EUT 1.

Fig. 4: Setup

5.3 Immersion Test

Measure and record the immersion water temperature. Condition the EUT at a temperature 10°C higher than the water temperature. Close all sealed areas and valves; assemble the EUT in its test configuration and, as quickly as possible, immerse the EUT in water so that the uppermost point of the EUT is 1 m below the surface of the water. The orientation of the EUT should represent that of its expected in-service orientation. If several orientations are possible, select that which is most severe. Following a 30-minute immersion period, remove the EUT from the water, wipe the exterior surfaces dry (giving special attention to areas around seals and relief valves) and, if applicable, equalize the air pressure inside by activating any manual valves. Be careful to not allow water to enter the EUT while activating the manual valves. Open the EUT and examine the interior and contents for evidence of, and quantity of any leakage and, if leakage occurred, for probable areas of entry.

The test is performed with EUT 2.

5.4 Shock Test

The EUT is fixed on the shaker with fixation devices (tension belts). With the shaker in vertical direction, the EUT is fixed in three different (mutual perpendicular) axes. Fig. 9 to 11 show the position and fixation on the shaker.

The shock pulse is a half sine pulse with a duration of 11 ms and a peak acceleration of 40 g. Three positive and three negative shocks are applied.

The test is performed with EUT 1.

5.5 Random Vibration Test

The EUT is fixed on the shaker with fixation devices (tension belts). The EUT is fixed on the shaker in three different (mutual perpendicular) axes / positions. Fig. 9 to 11 show the position and fixation on the shaker.

There are three different levels of vibration exposure:

Vertical: 10 -500 Hz; g

Longitudinal: 10 -500 Hz; g

Transversal: 10 -500 Hz; g

Level 1.04

rms

Level 0.20

rms

Level 0.74

rms

The vertical level is applied in vertical axis (z-Axis), the transversal level is applied in x-Axis transversal and y-Axis (longitudinal).

The exposure duration is 1.5h per axis, representing a transportation distance of approximately 2.500 km.

The test is performed with EUT 1.

5.6 Loose Load Vibration Test

The cargo has freedom to bounce, scuff and collide with other cargo and with the sides of the vehicle. The loose cargo environment includes conditions experienced by cargo transported in a vehicle traversing irregular surfaces. This test replicates the repetitive random shock environment incurred by cargo transported under these conditions.

A duration of 20 minutes represents 240 km (150 miles) of transportation (encompassing truck, two-wheeled trailer, and tracked vehicle), over the various road profiles found in the transport scenario from the Corps Staging Area to a Using Unit.

Two methodology studies (paragraph 6.1, references g and h) determined that a standard package tester (300 rpm, circular synchronous mode), provides a reasonable simulation of the loose cargo transportation environment. The movement of the package tester bed is a 2.54 cm (1.0 inch) diameter orbital path at 5 Hz (each point on the bed moves in a circular path in a plane perpendicular to the horizontal plane). The test item is allowed to collide with established test setup restraints.

Fig. 11 shows the setup on the loose load vibration teable (package tester).

The test is performed with EUT 1.

6 Test and Results

6.1 Temperature Shock

The test is performed with the specified parameters (see Tab. 2). During the test no visible changes were observed.

6.2 Drop Test

The test is performed with the specified parameters (see Tab. 2). During the test visible changes were observed. During the drop on face 3, the closing devices (buckles) opened halfway (see Fig. 13); They were closed and the drop test continued. During the drop on face 1, the case opened completely (see Fig. 14).
