2.13 Reliability

2.14 Agency certification

2.14.1 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.

2.14.2 Electromagnetic compatibility

Hard drives that display the CE mark comply with the European Union (EU)

requirements specified in the Electromagnetic Compatibility Directive (89/

336/EEC). Testing is performed to the levels specified by the product stan-

dards for Information Technology Equipment (ITE). Emission levels are

defined by EN 55022, Class B and the immunity levels are defined by EN

55024.

Seagate uses an independent laboratory to confirm compliance with the EC

directives specified in the previous paragraph. Drives are tested in represen-

tative end-user systems. Although CE-marked Seagate drives comply with

the directives when used in the test systems, we cannot guarantee that all

systems will comply with the directives. The drive is designed for operation

inside a properly designed enclosure, with properly shielded I/O cable (if nec-

essary) and terminators on all unused I/O ports. Computer manufacturers

and system integrators should confirm EMC compliance and provide CE

marking for their products.
