18 Barracuda Serial ATA V Product Manual, Rev. B
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.
Korean RRL
If these drives have the Korea Ministry of Information and Communication
(MIC) logo, they comply with paragraph 1 of Article 11 of the Electromagnetic
Compatibility control Regulation and meet the Electromagnetic Compatibility
(EMC) Framework requirements of the Radio Research Laboratory (RRL)
Ministry of Information and Communication Republic of Korea.
