m = 21.2 x 106
95% confidence level = 3.1 x 106
17 contacts out of 20 achieved 10 million no miscon-
tact operations.
5. High temperature test
Test conditions:
Ambient temperature: 80°C ±2°C
Test method:
1. All contacts were switched for 100 operations on 2
A 30 V DC resistive load.
2. Samples then were exposed to 80°C temperature
for 5,000 hours, continuous
3. Contact resistance was measured with Hewlett-
Packard testing equipment.

Exposure, hrs.
Test result:
Amber relays showed a stable spread of contact resis-
tance within the initially specified 50 mW after 5,000
hours exposure.
NOTES
1. Prevention of vibration and shock
To reduce the likelihood of vibration and
shock, we recommend that you install so
that the contact action is not in the direc-
tion of gravity.
