2.10.1 Test for Prominent Discrete Tones (PDTs)
Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this
process is the use of the absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 389-
7) to discern tone audibility and to compensate for the inaudible components of sound prior to computation of
tone ratios according to Annex D of the ECMA-74 standards.
2.11 Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in
performance when subjected to the radio frequency (RF) environments defined in the following table:
2.12 Warranty

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
Electromagnetic 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 EN55022, Class B and the immunity levels are defined by EN55024.
