1.10 Electromagnetic susceptibility
The drive operates without errors when subjected to the following:
1.11 Reliability
1.12 Agency certification
1.12.1 Safety certification
The drives are recognized in accordance with UL 1950 and CSA C22.2
(950) and meet all applicable sections of IEC950 and EN 60950 as tested
by TUV North America.
1.12.2 Electromagnetic compatibility
Hard drives that display the CE marking comply with European Union
requirements specified in Electromagnetic Compatibility Directives.
Testing is performed to standards EN50082-1 and EN55022-B.
Seagate uses an independent laboratory to confirm compliance with the
EC directives specified in the previous paragraph. Drives are tested in
representative end-user systems. Although CE-marked Seagate drives
Radiated noise ≤ 3 volt/meter, 30 Hz to 500 MHz
Electrostatic discharge* ≤ 10 KVolts
Magnetic field strength ≤ 5 Gauss
* Electrostatic discharge susceptibility is measured with the drive
mounted in a representative computer system (mounted to a
ground plane with an earth ground). Discharges are applied to the
bezel or other external surfaces on the ground plane.
