2.12 Reliability
2.12.1 Annualized Failure Rate (AFR)
The product will achieve an Annualized Failure Rate (AFR) of 0.55% when operated in an environment of
ambient air temperatures of 25
°C. Operation at temperatures outside the specifications in Section 2.9 may
increase the product AFR. AFR is a population statistics that is not relevant to individual units.
AFR specifications are based on the following assumptions for desktop personal computer environments:
• 8760 power-on-hours per year
• 10,000 average motor start/stop cycles per year
• Operations at nominal voltages
• Temperatures outside the specifications in Section 2.9 may reduce the product reliability.
• Normal I/O duty cycle for desktop personal computers. Operation at excessive I/O duty cycle may degrade
product reliability.
The consumer electronics environment of power-on-hours, temperature, and I/O duty cycle affect the product
AFR. The AFR will be degraded if used in a enterprise application.
2.13 Agency certification
2.13.1 Safety certification
These products are certified to meet the requirements of UL60950-1, CSA60950-1 and EN60950 and so
marked as to the certify agency.
2.13.2 Electromagnetic compatibility
Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Elec-
tromagnetic Compatibility Directive (2004/108/EC) as put into place 20 July 2007. Testing is performed to the
levels specified by the product standards for Information Technology Equipment (ITE). Emission levels are
defined by EN 55022, Class B and the immunity levels are defined by EN55024.
Drives are tested in representative 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
necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators should
confirm EMC compliance and provide CE marking for their products.
