2.14.3 Taiwan Requirements — Taiwan RoHS
Taiwan RoHS refers to the Taiwan Bureau of Standards, Metrology and Inspection’s (BSMI) requirements in standard CNS 15663, Guidance to
reduction of the restricted chemical substances in electrical and electronic equipment. Seagate products must comply with the “Marking of
presence” requirements in Section 5 of CNS 15663, effective January 1, 2018. This product is Taiwan RoHS compliant.
The following table meets the Section 5 “Marking of presence” requirements
.

Corrosive Environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments
containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every
potential application environment.
Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive
component reliability can be affected by the installation environment. The silver, copper, nickel and gold films used in Seagate products are
especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic
components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient
relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should
be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free
alternatives.
Seagate recommends that data centers be kept clean by monitoring and controlling the dust and gaseous contamination. Gaseous contamination
should be within ANSI/ISA S71.04-2013 G2 classification levels (as measured on copper and silver coupons), and dust contamination to ISO 14644-1
Class 8 standards, and MTBF rated conditions as defined in the Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF) section.
