Ceramic Discriminator
6. PHYSICAL AND ENVIRONMENTAL CHARACTERISTICS
6.1 Vibration
Discriminator shall be measured after being applied vibration of amplitude to
1.5mm with 600 to 3,300 r.p.m band of vibration frequency to each of 3 perpendicular
direction for 24 hours. The measured values shall meet Table 1.
6.2 Random Drop
Discriminator shall be measured after 3 times random dropping from the height of
30cm on concrete floor. The measured values shall meet Table 1.
6.3 Temperature Characteristics
Discriminator shall be measured within -20℃ to +80℃ temperature range. The
measured values shall meet Table 1.
6.4 Humidity
After being placed in a chamber within +90 to 95% R.H. at +40±2℃ for a
period of min.100 hours and then being placed in room temperature for 24 hours, the
discriminator shall be measured. The measured values shall meet Table 1.
6.5 Life Test(High Temp.)
The discriminator shall be measured after being placed in a chamber with 80℃
for 100 hours and then being placed in room temperature for min.24 hours. The
measured values shall meet Table 1.
6.6 Life Test(Low Temp.)
The discriminator shall be measured after being placed in a chamber with -20℃
for 100 hours and then being placed in room temperature for min.24 hours. The
measured values shall meet Table 1.
6.7 Thermal Shock
After temperature cycle from -20℃(30 minutes) to +85℃(30 minutes) was
performed 5 times and then being placed in room temperature for min.24 hours. The
measured values shall meet Table 1.
