6.1.2 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.
6.1.3 Radiation
noise
The disk drive shall work without degradation of the soft error rate under the following magnetic flux density limits
at the enclosure surface.
Frequency (KHz)
Limits (uT RMS)
0–60 500
61–100 250
101–200 100
201–400 50
Table 12. Magnetic flux density limits
6.1.4 Conductive
noise
The disk drive shall work without soft error degradation in the frequency range from DC to 20 Mhz injected through
any two of the mounting screw holes of the drive when an AC current of up to 45 mA (p-p) is applied through a
50-ohm resistor connected to any two mounting screw holes.
6.1.5 Magnetic
fields
The disk drive will withstand radiation and conductive noise within the limits shown below. The test method is
defined in the Noise Susceptibility Test Method specification, P/N 95F3944.
