Test name Bench handling Standard HP internal Electrostatic discharge (ESD) IEC 801-2, Contact discharge; 4kV and 8kV; air discharge: 15kV Removable hard drive Handling while outside unit Bench handling specification Test description Unit is dropped on each of the 4 edges of the base of the product on a typically used bench surface. Operating mode: Each edge is dropped 25 times at 10-second intervals, from a height of 7 cm. Nonoperating mode: Each edge is dropped 50 times at 10-second intervals, from a height of 10 cm. Unit external contacts, connectors, and screws are subjected to 5 discharges per polarity per kV, first with no external power and second with external power, and then with peripherals. At ± 4kV: No noticeable effects At ± 8kV: No data or program loss; unit reboots, resets At ± 15kV: No component failure (hard error) Unit is operating, accessing disk. Removable hard drive is checked after the drive is dropped onto a typical bench surface from a height of 5 cm, 25 times, with a time interval of 5 seconds between drops. Drive is tested while removed from unit and therefore is nonoperating.
