Corrosion test
The hard disk drive must be functional and show no signs of corrosion after being exposed to a
temperature humidity stress of 50°C/90%RH (relative humidity) for one week followed by a temperature
and humidity drop to 25'C/40%RH in 2 hours.

Atmospheric condition
"Environments that contain elevated levels of corrosives (e.g. hydrogen sulfide, sulfur oxides, or
hydrochloric acid) should be avoided. Care must be taken to avoid using any compound/material in a
way that creates an elevated level of corrosive materials in the atmosphere surrounding the disk drive.
Care must also be taken to avoid use of any organometallic (e.g. organosilicon or organotin)
compound/material in a way that creates elevated vapor levels of these compounds/materials in the
atmosphere surrounding the disk drive."
