Table 2. Additional HP nr3600 Rugged Notebook tests (unit in vehicle cradle) Test name Vehicle vibration (operating) Vehicle vibration (contact continuity) Vehicle shock (contact continuity) Vehicle crash Standard ASTM 4169-99 Truck Assurance Level II, Schedule E MIL-STD 810F, Method 514.5, Procedure I, Category 24 SAE J1455 Pothole Shock (4.10.3.4) SAEJ1455, Crash Shock (4.10.2.4) Test description Unit is subjected to vibration for 90 minutes across each of the 3 axes described in the earlier Vibration test. Unit is operating, accessing disk. Unit is subjected to 2 tests across 3 axes: 1 hour per axis and 30 minutes per axis. Unit is nonoperating. Unit is mounted in a vehicle and subjected to a total of 18 shocks of a 20-millisecond duration, such as might be encountered by sudden acceleration, braking, or turning. Unit is subjected to 4 lengthwise 30-mph vehicle crash simulations in each of 4 orientations for a force of 20G and duration of 120 milliseconds with one rebound. Summary As can be seen in the detailed test descriptions, HP testing standards provide for outstanding ruggedness verification. By conducting such rigorous qualification tests for its rugged systems, HP is driving industry standards to best ensure that the needs of this special class of customers are met.
